Title: Improvements relating to ultra-high-frequency electron-discharge apparatus
IPC: H01J25/12
Filed: 1945-08-27
Abstract: 597,998. Velocity-modulated tubes. SPERRY GYROSCOPE CO., Inc. Aug. 27, 1945, No. 22036. Convention date, Aug. 25, 1944. [Class 39 (i)] In an ultra-high-frequency electron discharge apparatus, a beam of electrons from a gun 14 is velocity modulated on passing through a cavity resonator 11 excited by an ultra-highfrequency field through input loop 27, is density modulated in drift tube 19 and has energy extracted from it in resonators 16 and 21, both excited to the input frequency and coupled by a common grid 18 and by a phase-shifter 33 connected between the coupling lines 28 and 31. The resonators 11, 16, 21 are individually tunable by means of elastic membranes 36, 37, 38 and screws 44, 47, 48 engaging plates 39, 41, 42 and 43 rigidly connected to the outer wall of resonator 11, drift tube 19, the outer walls of resonators 16, 21 and the supports of grid 23 respectively. The distances between the pairs of grids 12, 13 ; 17, 18 ; 18, 23 can thus be varied according to the frequency required. Tension springs 51 are coupled between the members 39, 43 to take up backlash and members 41, 42, 43 are suitably apertured to give free passage of the spring and permit access to the screws 47 and 48. The phaseshifter 33 is adjusted to phase delay the energy travelling from resonator 16 to 21 by the same phase-shift as is produced by the transit time of the electron bunches between the two output resonators or differing therefrom by an integral number of cycles, and all resonators are tuned to the input frequency. Alternatively, one resonator may be tuned above the frequency of the electron stream while the other is tuned below by the corresponding amount and the phase-shifter dispersed with. Three or more output resonators may be similarly coupled together. In a modification (not shown), the input may be into a resonator tuned to a frequency sub-harmonically related to that of the output resonators.

Title: Apparatus for constructing a reduced information content hologram
IPC: G03H1/34
Filed: 1971-04-19
Abstract: 1316905 Holography BENDIX CORP 19 April 1971 [26 Feb 1970] 22048/71 Heading G2J Holograms having reduced information content (and thus requiring less bandwidth for transmission than before), are formed by containing the parallax information along one axis only. An object beam 18 illuminates an object 20 and the modulated beam passes a cylindrical lens 22 which forms the beam into a single line along axis 38 in its back focal plane where it interferes with reference beam 14 to form a hologram 40. Upon reconstruction the hologram is viewed through an equivalent cylindrical lens (48), Fig. 2, (not shown). Details are given regarding the spacing of object-lens, lens-hologram; imagehologram, hologram-lens. These relative distances can be altered for a given set-up by interposing a diverging or conveying lens in the reference and reconstruction beams. In a further embodiment (Fig. 5) the invention is used in a real-time television system 60, 64. The hologram 40 is converted into a set of electrical signals which are transmitted and reformed on an electro-optic face-plate 92 of a cathode ray tube. A three-dimensional image is reconstructed by illuminating the face-plate 92 with a coherent beam and viewing the image through a cylindrical lens 48.

Title: Weighing scales
IPC: G01G19/00
Filed: 1944-11-09
Abstract: 594,779. Weighing-apparatus. DEHN, F. B. (Fairbanks, Morse & Co.). Nov. 9, 1944, No. 22099. [Class 143] In a portable platformtype scale comprising base and platform members with a compound lever system in between, the lever system comprises two longitudinal primary levers having their tip ends below their butt ends, the tip ends being linked to the butt end of a longitudinal secondary lever, and a transverse tertiary lever, below the butt end of one of the primary levers, having its butt end linked to the tip end of the secondary lever and its butt end connected to a longitudinal weigh beam lever. A pair of bearing blocks 17 are mounted on transverse end members 16 of a spider 15 which carries the platform 11, and seat on pivot blocks 18 secured to the inner sides of end portions 19, 20 of the primary levers 21, 22, the outer sides each having secured to it a pair of fulcrum steels 23 seated on bearing blocks 24 secured to the base. The primary levers 21, 22 curve downwardly and laterally and have bifurcated ends side by side near one edge of the housing pivoted in bearing blocks in link members 29, 30 suspended from a pivot element connected across the dual slotted end of the secondary lever 34 which is pivoted on a stand 35. The other end of the lever 34 is mounted on a loop 38 linked to a bearing loop 39 which is connected to one end of the tertiary lever 41 extending through an opening in the side flange 12 of the base, its other end being connected to a weigh beam 45 of known type. Headed retainer studs 52 pass through openings in projections 51 on the end portions 19, 20 of the primary levers and screw into the base. Similar studs 54 pass through openings in projections 53 on the spider and screw into end portions 19, 20. As the spider is connected to the platform, excessive vertical separation of the platform and base is thus prevented. To prevent lateral displacement of the two, a flexible rectangular plate 55 is fastened at one end to the top of a stand attached to the base and at its other end, after passing through an opening in a rib forming part of the spider, to a bracket 56 projecting from the rib, grooves 60 adjacent its secured ends lessening its opposition to movement normal to its plane. Handles 63, 64 may be used to carry the scale or, in conjunction with castors 61, to wheel it.

Title: Method and means for operating metal extrusion presses
Inventor: LORANT HUGO
IPC: B21C35/04
Filed: 1955-08-03
Abstract: 781,737. Extruding. LORANT, H., and LOEWY ENGINEERING CO., Ltd. Aug. 3, 1955, No. 22248/55. Class 83 (4). In the extrusion of metal billets wherein, after the extrusion, a discard D and a shell S, Fig. 3, remain in the container bore 13, the discard and shell are removed by moving the die 14 out of alignment with the container bore so as to leave a discharge space 24 between the container 12 and the fixed platen 10 of the press, Fig. 4 (not shown), whilst the front end of the container is positively supported against the platen 10 by a spacing member or members, and ejecting the discard and shell from the container bore into said space and out of the press. The die 14 is mounted on a die carrier 15 slidable transversely along the guides 18, Fig. 1, on the platen 10. The spacing member or members preferably comprise part of the carrier 15 or an extension thereof. In the extrusion of tubes, Fig. 1, the billet B is first pierced by a mandrel 21 and is then extruded through the annular die orifice by a pressing stem 19 having a pressing disc 20 of smaller diameter than the container bore 13 so as to leave in the. container bore a thin shell S. When billets of metals such as brass or copper are extruded at elevated temperatures, oxides are present at the surface of the billet and these oxides remain in the shell and are not extruded. After extrusion the container 12 is retracted, Fig. 3, the die carrier is moved transversely to the position of Fig. 4 (not shown), and the discard D together with the disc 20 is removed from the container bore by the stem 19, the discard being sheared from the shell S. Thereafter a larger disc 27, Fig. 5 (not shown), is placed on the end of the stem 19 and the latter is operated to remove the shell S from the bore into the space 24. Alternatively the discard and shell together with the disc 20 may be removed as a unit. In another embodiment, Fig. 8, the carrier 15b has an aperture 24b closed at one end by a disc 26 to provide an ejection space for the discard and shell, both of which may be removed as a unit by a disc 27 on the end of the stem 19 which presses the discard against the plate 26 and crushes the shell until it is disposed entirely within the aperture, Fig. 9 (not shown). The bottom of the aperture is closed by a flap 28, Fig. 10 (not shown) when the carrier is in the position shown in Fig. 8, but when the die 14 is returned into alignment with the container bore the flap opens automatically to allow discharge of the discard and shell. In this embodiment the discard and the shell may alternatively be ejected separately. The die carrier may be rotatable instead of slidable. Specification 549,880 is referred to.

Abstract: 928,444. Electronic computers. ELECTROLOGICA N.V. June 30, 1959 [June 30, 1958], No. 22356/59. Drawings to Specification. Class 106 (1). An electronic computer is provided with an interrupt facility in which each of a number of independent programmes is assigned a priority rank, and a call from an external unit of a programme of higher priority than that currently being executed will cause interruption by the higher priority programme. The Specification describes and illustrates schematically control circuitry in which seven such programmes may call for use of the computer (an eighth programme with " no urgency," i.e. in which any programme step may be carried out at any time, may be used to take up spare time from the others). In this example the contents of four computer registers are each transferred in turn to consecutive memory addresses of a block of 32 reserved for the eight programmes, one of these registers containing the address of the current instruction. Flip-flop registers are used to control the interruption (which takes place after execution of the instruction being executed when a call is received) and record the programme currently being executed.

Title: Improvements in and relating to the tempering of glass
IPC: C03B27/052
Filed: 1936-08-14
Abstract: 479,878. Tempering glass. SOC. ANON. DES MANUFACTURES DES GLACES ET PRODUITS CHIMIQUES DE ST.-GOBAIN, CHAUNY, & CIREY. Aug. 14, 1936, No. 22433. Convention date, Sept. 5, 1935. [Class 56] A cooling - device for tempering glass articles comprises a casing which substantially encloses an article, a number of inlet passages adapted to admit cooling medium to the interior of the casing, and one or more outlet passages to provide an escape for the cooling medium, the outlet passages being of such a size and so located relatively to the inlet passages that the flow of cooling medium is adapted to produce the desired degree of tempering at any portion of the surface of the article. Fig. 1 shows in section a device for tempering a glass article q of triangular section, such as a pavement light, which is to be cooled more rapidly along its edges than at its sides. The article q is enclosed in a casing a having parts a<1>, a<2> of its walls which are closer to the surface of the article than the parts adjacent the edges. The latter parts are double and enclose spaces m into which the cooling medium is introduced from pipes f and from which it passes through passages g into contact with the glass article. Tubes h through the walls provide an escape for the cooling medium, and outlet passages d are formed in the walls a<1>, a<2> for a similar purpose. The cooling medium thus flows over the surface of the article and diminishes in volume with increasing distance from the edges. In a modified construction, the cooling medium is introduced into the enclosure at the edges of the article and flows over its surface. The side walls of the enclosure are formed with outlet passages each provided with a valve to regulate its area. Fig. 3 shows a device for tempering a glass sheet so that zones of the sheet are highly tempered and are surrounded by zones which are less highly tempered. Portions k of the walls of the casing are at a greater distance from the glass sheet l than other portions j, and the portions k are provided with inlet passages g surrounded by outlet passages h. The parts of the glass sheet facing the wall portions j are less highly tempered.

Title: The treatment of semi-conductor wafers
IPC: H01L21/00
Filed: 1964-05-29
Abstract: 1,016,662. Semi-conductor devices. SIEMENS-SCHUCKERTWERKE A.G. May 29, 1964 [June 1, 1963], No. 22456/64. Heading H1K In a method of spacing the members of a stack of wafers of semi-conductor material during treatment a reciprocatory motion is imposed on the stack to cause during the treatment repeated relative motion, in the directior of stacking, of adjacent wafers. As shown a stack 6 of disc-shaped wafers of semi-conductive ma terial is supported in a jig comprising a base 5 of quartz or silicon rods 2, 3 and 4 of quartz and a plunger 8 driven by a motor 9. In use plunger 8 reciprocates in a vertical direction and shakes the stack of wafers which bounce apart thus preventing their faces from adhering to each other. The plunger 8 may be mounted so that it makes contact with the stack of wafers either at the centre or near to the edge. The jig may be enclosed in a sealed container and the stack of wafers may be of alternate conductivity types or have different doping levels and may be subjected to a temperature gradient in a suitable atmosphere to cause a transport reaction to occur whereby semi-conductor material from each wafer is epitaxially deposited on the next wafer in the direction of decreasing temperature. If the wafers are of silicon the atmospheres may be a mixture of silicochloroform and hydrogen. The motor 9 can be a rotating device operating plunger 8 through a cam or may be a reciprocating motor. The frequency of the oscillatiion of the plunger may be about 100 c/s. and the stroke may be between 5 Á and 500 Á depending on the desired mean spacing of the wafers. In a second embodiment a quartz tube mounted vertically inside a resistance furnace and through which a stream of hydrogen containing silicochloroform or silicon tetrachloride is passed, contains a stack of wafers of semiconductor material which are spaced apart by vibrating the quartz tube by means of a plunger and motor. The method may also be used during diffusion and oxidation processes.

[Class 98 (i).] To facilitate entry and escape of air when a bellows camera is being opened and closed (and vice versa), the spool housing E has an inner wall G spaced from the camera wall A<2>. The wall G forms an extension of the rear frame F<2>. The upper and lower end members Fl of this frame are recessed below the side members F which determine the focal plane and on to which the film is pressed by a resilient back-plate. The air passes from the bellows, as indicated by arrows, between the recessed ends F<1> and the film, through the spool housing and an opening H<1> at the end of the wall G. The outlet opening H<2> from the space H opens into the central part A<1> of the camera and is shut off by the folding baseboard B when the camera is closed, thereby excluding dust. Dust and light are further excluded by baffle spacing pieces J in the space H. Specification 398,597 is referred to.
Patent GB-225633-A (GB)
Abstract: 225,633. Carey, R. F. Sept. 10, 1923. Rectilinear-motion bearings; fluid bearings.-A device which can be used as a castor or bearing to facilitate the moving of heavy bodies, and by which the supported body may be raised a limited amount, comprises a ball or roller A acting as a piston in a cylinder D containing hydraulic medium such as grease, oil, petroleum jelly &c. under pressure which can be controlled. Normally, the cylinder rests on the ground and acts as a supporting foot. By increasing the pressure of the medium, or admitting a further quantity of medium under pressure from a suitable reservoir, the ball &c. is caused to project from the cylinder, thus raising the cylinder and body supported thereby. The ball then acts as a castor. The device may also be used inverted, the cylinder being fixed. The projected ball &c. lifts and forms a bearing for a track member supporting the load to be moved. Leakage of medium may be minimized by a packing ring P, or by the use of additional balls &c. B, C. Means may be provided to supply medium to make up loss due to leakage. As shown, the cylinder D is surrounded by a jacket L to which a frame M supporting the load is secured. Pressure is applied to the medium by a cap member I which can be screwed up and down a projection E on cylinder D by handles N. A form is described employing a single ball or roller, and in which there is a valve controlled supply of medium under pressure from a reservoir. A check valve, the stem of which rests on the upper surface of the ball, is unseated when the ball is within the cylinder, but seats to cut off supply of the medium when the ball is projected the required distance. Fig. 3 shows in plan three devices of the kind shown in Fig. 1, applied to a frame T for moving a shell, shown in broken lines. The handles N are operated to project the balls or rollers to allow the frame to be moved under the shell and are then further operated to lift the shell and allow it to be moved.
