Title: Lithographic printing plates
IPC: B41N3/03
Filed: 1964-09-16
Abstract: 1,084,512. Photographic transfer process. EASTMAN KODAK CO. Sept.16, 1964 [Sept. 20, 1963], No. 37838/64. Heading G2C. Lithographic printing plates are prepared by imagewise exposing an unhardened silver halide/ gelatine layer, developing in the presence of a tanning developing agent to form a hardened gelatine image therein, pressing the wet developed layer in contact with a receiving plate comprising a supported layer of a hardened colloid and an inert pigment which has been overcoated with a non-tanning silver halide developer, so as to transfer a stratum of the emulsion from the non- image areas of the silver halide layer to the hardened colloid layer. Suitable receiving plates are described in Specification 1, 084, 513. Prior to inking the printing plates are preferably heated and then treated with a solution of a bivalent metal salt (e.g. zinc acetate) and/or a solution of glycerine and phosphoric.

Title: Supply installation for apparatus treating pulverulent material
IPC: F23K3/00
Filed: 1956-12-11
Abstract: 796,127. Pneumatic conveyers. HERMANNS, W. Dec. 11, 1956, No. 37854/56. Class 78 (1). In a supply installation, Fig. 1, for apparatus 1, e.g. the furnaces of an aluminium works, which treats pulverulent material and which is connected to branch pipes of a closed circuit pipe line 3 into which the contents of a storage bin 2 are forced by pneumatic pressure and which returns to the bin the material which is not discharged through the branch pipes, a separate feed container 4 is connected to the input side of each apparatus 1, these containers being connected in parallel to the pipe line 3 and the connections between the parts 3, 4 and also between the parts 4, 1 are adapted to be made and cut off alternately. Each container 4 is connected to the line 3 by pipes 5, 6 provided with cut-off valves 7, 8. The outlet 9 of each container is connected to a hose 10 having a cut-off valve 11 which is actuated by a lever 12 mounted on the end of the hose. When the hose is not connected to an apparatus 1, it is hung on a hook 13 connected to the valves 7, 8 and its weight causes them to open. These valves close as soon as the hose is taken off the hook. Material in the bin 2 is discharged by a rotary device 15 to a hammer mill 16 from which it is forced by a pump 17 into the line 3. Material will pass into any container through the pipe 5 if its hose is hung on the hook and the conveying air will flow back through the pipe 6 into the line. Mixed air and pulverulent material returns to the bin 2 through the pipe 18 and the air escapes to atmosphere through a dust-separating device 19. Asbestos hoses having air-permeable walls and connected to a supply of compressed air are laid on the bottom 9 of each container 4 and a similar hose may be placed within each hose 10.

Title: Aircraft training apparatus for visual landing approach
IPC: G09B9/30
Filed: 1962-10-05
Abstract: 961,794. Training aircrew. CURTISS-WRIGHT CORPORATION. Oct. 5, 1962 [Oct. 19, 1961], No. 37858/62. Heading B7W. Apparatus for simulating an aircraft night landing approach comprises a simulated landing field having apertures representing an array of approach and landing lights and illuminated from a light source, and optical pick-up and projecting means presenting the display to a trainee, the landing field and pick-up being relatively movable in accordance with simulated aircraft attitude. Fig. 1 shows a simulated landing strip L having landing lights 1 and approach lights 2, which may shine steadily or flash in sequence to give the impression of a light moving towards the runway. A television camera 3 is moved relative to L by servos controlled by a flight computer responsive to movements of the dummy controls in a mock cockpit T. A television projector 3b is focused on a screen 5 in front of the trainee. A fluorescent tube (not shown) extends the length of the strip L on its underside, and simulated landing lights 1 are provided by transparent plastic inserts extending through the strip. Each insert has a conical recess in its top, so that light passing up through the insert is reflected at a low angle to the plane of the strip. Each approach light 2 is simulated by an aperture 12 in a cover strip 16, overlying an opening 17 in panel 4, Fig. 2. Each aperture 12 is normally covered by a shutter 11 mounted on a lever 10 pivoted on axis 10a. The other end of each lever forms a cam co-operating with a roller 9b on a cam arm 9 secured to shaft 7, the set of rollers 9b lying on a helix coaxial with shaft 7. Each shutter has a row of small apertures, so that rows of approach lights are simulated. To simulate the flashing light sequence, shaft 7 is rotated by motor 5, the cam arms 9 displacing the levers 10 in sequence going towards the runway, to uncover apertures 12 in sequence. When the flashing light sequence is to be stopped, a cam on shaft 7 operates a microswitch to ensure that motor 5 is de-energized and a solenoidcontrolled brake is applied to the shaft, only when the angular position of the shaft is such as to leave all apertures 12 shuttered. A mirror is mounted above each aperture 12 to direct the light towards the camera. Light baffles prevent light from each aperture from reaching the camera other than by such reflection.

Title: Apparatus for applying radioactive therapy in the pelvic cavity of the body
IPC: A61N5/10
Filed: 1959-11-09
Abstract: 867,756. Apparatus for radioactive therapy. CLAYTON, R. S. Nov. 9,1959, No. 37909/59. Class 98(1) A radioactive material applicator comprising a frame on which the radioactive material is mounted can be secured in position within the pelvic cavity of a patient. The basic structure of the frame is a three-armed spider 10 mounted movably on a central post 38. Two of the arms (11, 12) carry slidably extensible brackets 14, holes 18 at the ends enabling the bracket to be secured to the pubic bone 19 by screws 21. The third arm 13 carries a similarly slidable bracket 25 having an offset part 29, thus enabling a tongue 30 at its end to be attached by screw 32 to the fifth lumbar vertebra 33, or possibly the sacrum. The slidable brackets can thus be adjusted for different shapes and sizes of pubic cavities and of bone structure. A cylindrical crosspiece 42 having a central bore 45 is adjustably mounted on the post 38, and carries the supports 50 on which are attached the actual radioactive elements. Each support 50 is on a stud 51 which slides in the bore 45 and is held therein by set screws 46. These supports are shaped to conform with the walls of the pelvic cavity, and can be made of wood, hard rubber. or a plastic such as Lucite. Since the supports 50 are readily detachable from the cross-piece 42, a number of such supports of different shapes and sizes may be held available, suitable selection being made to fit the particular patient. The radioactive material itself (e.g. radium chloride, or radioactive cobalt, caesium, or gold) is contained in tubes 58 of various lengths and sizes, as desired, and these tubes are attached to the supports 50 by spring clips. A bracket 72 at the foot of the post 38 carries a further support 71 similar to the supports 50, intended for irradiation of the floor of the pelvic cavity. Lead bars 62, 64, 76 are attached along the edges of the supports, to prevent radiation from reaching parts of the body where it is not required. Restrainer plates 78 and 83 are provided for holding such organs as the bladder and rectum out of the irradiation zone. If irradiation of one wall only of the pelvic cavity is required, only one lateral support 50 need be used (Fig. 3). The device is placed within the pelvic cavity by a surgical operation. All the interchangeable and movable parts are selected and adjusted so that the device is properly fitted and positioned within the patient, the predetermined amount of radioactive material loaded on the supports, and the device screwed securely in position. The entire device may be surrounded by a plastic lining. It is left in position for about five days, and then removed by a further operation.

Title: Tamper-proof axial tumbler lock
IPC: E05B27/08
Filed: 1969-07-30
Abstract: 1,269,418. Barrel locks. CHICAGO LOCK CO. 30 July, 1969 [5 Aug., 1968], No. 38285/ 69. Heading E2A. An axial tumbler barrel lock is protected against picking by dividing the rotatable barrel into two parts 16, 18, the tumbler pins being also divided into parts 36, 40 separated by a ball 42, such that any picking attempt has the effect of moving the pins into the position shown in Fig. 9 or 10 allowing ineffective rotation of the front barrel 18, while the part 16 which is coupled to the bolt 27 is held against rotation by pin part 38 or 40 engaging in fixed barrel part 14. This fixed barrel is secured housing 12 by a pin 20. When the correct key 100 is used, the balls 40 of all seven tumblers, lie on the interface between barrel parts 16 and 18 to provide a drive between them, the rearward tumbler parts 38, 40 meeting at the interface with the fixed feather 108 engaging in slot 74. A notch 80 65 in the shank lock face 62 ensures correct placing of the key which is guided on a pilot post 68 mounted in the front barrel by a tail 70. The key carries an internal guide feather 108 engaging in slot 74. A notch accommodates a spring-loaded limit pin projecting forwardly from the middle barrel 16  to limit the relative rotation of these two barrels and to urge the outer barrel into a forward position, Figs. 8 and 13. The key 100 has shoulders 106 for depressing the tumblers to the correct amount. A feather 110 enters a key 65 for correct alignment. When the key is inserted it pushes the front plug-part into contact with the middle one and thereafter the tumblers will be pushed back to the correct extent, Fig. 11. The key torque is transmitted through the pilot post 68 to the front barrel part. If a picking tool is inserted, it will push back the front plug part 18 as above, but this time the tumbler pins will be driven back so as to engage with the fixed barrel part to prevent rotation (Fig. 12, not shown). Eventually an intermediate situation, Fig. 9 or 10, is arrived at which frees the front cylinder but locks the intermediate one.

Title: Process and apparatus for preparing polymeric film
IPC: B29C48/08
Filed: 1973-08-14
Abstract: 1444757 Controlling thickness of extruded film E I DU PONT DE NEMOURS & CO 14 Aug 1973 [15 Aug 1972 (2)] 38458/73 Headings B5A and B5B [Also in Division G3] Thickness of an extruded flat thermoplastics film is regulated across its width by independent manual or automatic temperature control of one or more thermally isolated segments extending across the width of the die. The film is extruded on to a quenching surface comprising a stainless steel conveyer band or rotary drum, and then reheated and transversely and longitudinally stretched. In the described embodiment Fig. 2, the temperature of the thermoplastics in the outlet passage 32 of the die 10 is controlled to regulate its extrusion rate across the width of the passage by segments 13 each provided with a resistance heater and temperature sensor 15, and thermally insulated by an air gap comprising a slot 41 terminating upstream at a cylindrical bore 43. The extruding web W may be pinned across its width to a quenching drum 40, either by fluid from a conduit spaced across the drum W, or electrostatically by an electrode wire across the width of the web in combination with earthing of the drum. For manual control of the die segments, the effect of each segment 13 is calibrated, and the heat input to each segment manually adjusted according to the thickness recorded by a betaray scanner 17, Fig. 1, which traverses the web and records thickness variations which are displayed on a cathode ray tube. From automatic control of the web thickness, Fig. 1, a digital computer 18 is connected, through analog-to-digital converters 19a and 19b to the output of the temperature sensors 15 and the beta-ray scanner 17. Computer 18 compares the input data with a programmed thickness profile and determines the amount of electrical power to be supplied to the heating elements to obtain the desired thickness profile. The computer 18 distributes the power through a supply interface 16. Preferably, the computer initially distibutes power at a uniform level to all heaters, and then effects any necessary correction by preferably reducing the power input to a selected segment 13. The thermoplastics preferably comprises polyester, but may also comprise polypropylene, polyethylene or polyamides.

In use, a constant input signal V c  = S, Fig. 2, applied to gate electrode to gate electrode 15 during a time-interval [t 0 , t 2 ], and a negative-going pulse V D  applied to electrode 14 during a time-interval [t 0 , t 1 ], in combination with a positive-going lock pulse # 1  applied to electrode 16.1, cause a signal-independent amount of charge to be transferred from surface zone 11.5 to the site immediately beneath electrode 16.1. When the pulse V D  ceases at time t 1 , a signal-dependent amount of the charge in the site beneath the electrode 16.1 is transferred back to the surface zone 11.5 during the time-interval [t 1 , t 2 ], leaving a signaldependent amount of charge Q under electrode 16.1 for subsequent transfer to the other electrodes 16.2, 16.3, 16.4 &c. by clock pulses # 2 , # 3 , # 1  &c. It is stated that where C is the capacitance of the sandwich 16.1/ 13/11 directly beneath the electrode 16.1, R is the rest voltage of the clock pulses, and P the magnitude of the pulses. The time t 1  may be less than ¢t 2  and is preferably less than ¢t 2 . In modifications, the first electrode 16.1 may be clock pulsed independently of the others or may be connected to a D.C. voltage of value about R + P. The signal voltage V c  need not be constant, and the n- and p-type semiconductor properties may be interchanged.

Title: Process for the production of isothiazole and substituted isothiazole compounds
IPC: C08F210/00
Filed: 1962-10-12
Abstract: The invention comprises 4-methyl, 5-methyl, 4-cyano, 4-phenyl- and 5-phenyl isothiazoles. These and other isothiazoles are prepared by reacting compounds of the general formulae R1-CH2-CR2 = CHR3 and R1-CH2-C ­ CR3, in which R1, R2 and R3 are like or different and represent hydrogen, alkyl, aryl, aralkyl, alkaryl, acyl, nitrile or alkoxy groups, with sulphur dioxide and ammonia in the presence of solid dehydrating, cracking or dehydrogenating catalysts.  The preferred temperature range is 200-500 DEG  C.  Propylene is converted to isothiazole by the process of the invention.  Instead of propylene isopropyl alcohol, which is converted to propylene under the reaction conditions may be used as starting material. Similarly tertiary butanol and n-butyl acetate may be used instead of the corresponding butylenes.  Compounds which give sulphur dioxide, e.g. sulphurous acid, and ammonia, e.g. ammonium carbonate and ammonium carbamate, under the reaction conditions, may be used instead of sulphur dioxide and ammonia respectively.  Examples are given of the conversion of (a) propylene to isothiazole; (b) isobutylene to 4-methyl isothiazole which on oxidation with permanganate gives isothiazole-4 carboxylic acid; (c) butene-2 to 3- and 5-methyl isothiazole; (d) allyl cyanide to isothiazole nitrile; (e) methacrylonitrile to 4-cyanoisothiazole; (f) a -methyl styrene to 4-phenyl isothiazole; (g) b -methyl styrene to 5-phenyl isothiazole; (h) tertiary butanol to 4-methyl iso thiazole; and (j) methyl acetylene to isothiazole.
