Title: Calculating device
IPC: G06G1/00
Filed: 1972-04-11
Abstract: 1386272 Calculating device PEORIA JOURNAL STAR Inc 11 April 1972 [13 April 1971] 16673/72 Heading G4B A calculating device comprises a sleeve 1 receiving as a sliding fit an assembly of a slide 9 having an endless belt 7 trained therearound. With the assembly removed from the sleeve, the belt 7 can be moved round the slide 9 until a chosen value on a scale 11a, borne by the belt, is aligned with a datum line 13c, borne by the slide. With the assembly fully re-inserted in the sleeve (the position shown), the chosen value and datum line 13c, visible through sleeve window 5a, will be aligned with a datum line U of scale 3a, borne by the sleeve. The scales shown are logarithmic, the distance between any two values on scale 3a being equal to the distance between the corresponding values on scale 11a; if the chosen value is the number of units of foreign currency in one dollar, conversion between dollars and the foreign currency can be made by comparing adjacent values on scales 3a, 11a. Scales 3a, 11a are continued with some overlap, at 3b, 11b. The scales may be other than logarithmic, e.g. linear, square or square root, for purposes other than currency conversion, e.g. addition, subtraction or determining the length of the hypotenuse of a right angled triangle. Indicating the position of the decimal point.- Each face of the slide 19 (one shown in Fig. 5) bears two pairs of multi-coloured stripes (17A, 17B, 19A, 19B), 21A, 21B, 23A, 23B. The slide (plus belt) may be inserted into the sleeve with either of its ends at the bottom of the sleeve and either of its faces uppermost. By a suitable choice of these factors, a chosen one of the four pairs of stripes appears at windows 5a, 5b. The choice depends upon the order of magnitude of the particular currency conversion factor (referred to above), stripes 21A, 21B for example being appropriate if this factor lies between 10À0 and 100À0. The stripes 21A, 21B each comprise three differently coloured bands a, b, c defining decimal point position lines m, n, p. Corresponding lines m, n, p are defined by stripes 15a, 15b underlying scales 3a, 3b. With the slide positioned as shown in Fig. 1, a conversion factor of 25À78 units is set up alongside datum line U, line m lying between the digits 5 and 7 to indicate decimal point position. Then the line m, n or p which gives the decimal point position of a number of dollars read from scale 3a (e.g. line n for 23À20 dollars) is the same line as gives the decimal point position for the corresponding number of units on scale 5a (e.g. line n gives 600À00 units). Because the end-to-end position of slide 9 may be reversed in sleeve 1, the scales 11a, 11b are also printed in the reverse end-to-end position on belt 7, Fig. 6 (not shown).

Fig. 3 shows a modification wherein the burner heads e are supplied with air from a main k. Fig. 5 shows another construction wherein the flue is nearly filled by refractory blocks A' forming troughs or channels A in which burners B are located. Air is supplied to these by the central flue C and passages D. A similar structure, occupying rather more than the upper half of the flue, is shown mounted on a wheeled car-. riage on rails. The channels A may be fitted with spiral or disk baffles to retard the flow of combustion products. The gases, after passing off from the channels, may be drawn off by a fan and led through a water heater. Fig. 9 shows a boiler flue heated b gas and air supplied by pipes &c. C, E respectively, and burning in the channels A.
Patent GB-496591-A (GB)
Title: Improvements relating to means for reversing the movements of hydraulically operatedmachine tool slides
IPC: B23Q35/18
Filed: 1937-06-16
Abstract: 496,591. Hydraulically-operated machine-tools. ARCHDALE & CO., Ltd., J., and WRIGHT, I. H. June 16, 1937, No. 16709. [Class 69 (ii)] [Also in Groups XXII and XXIII] Means for effecting reversals of movement of a hydraulically-operated milling, grinding, or like machine-tool slide comprises spring or weight-loaded valves adapted to control the exhaust from the slide-operating cylinder and also the fluid for a reversing valve, and trip mechanism responsive to the slide movements for controlling the spring or weight-loaded valves. The slide f, Fig. 1, moved by the piston h in the cylinder g may carry a rotary tool a and a follower c co-operating with a pattern d, Fig. 2. A pump i draws fluid (usually oil) from a reservoir j and passes it through the reversing valve l and also to a pipe line u. In the position of the reversing valve shown, Fig. 1, pressure fluid passes through the pipe q to the trip-controlled valve m whence it passes through the pipe r to the cylinder g. Piston h and slide move to the right, fluid being exhausted through pipe s, second valve m, and pipe t to the reversing valve and reservoir. Near the end of a required stroke movement, the lever p is moved to free the right-hand valve m which moves to the left under the action of its spring n. This admits pressure fluid from the pipe u through the space y to the pipe v and thus moves the reversing valve and so effects the reverse movement of the slide f. Pressure fluid now passes through the space x in the right-hand trip valve from the pump i, and the valve is forced back against the spring pressure until re-engaged by the trip lever o. A similar reversal takes place when the slide reaches the opposite end of its movement. The trip lever p, in the embodiment described, is connected to a sliding rack bar 6, Fig. 2, engaged by a pinion 5 carried by a ratchet wheel 4. Spring- pressed pawls 3 are brought into engagement alternately with the ratchet wheel when the slide f approaches the ends of its movement, thus holding the ratchet wheel and giving movement to the rack bar to operate the valve trips. A follower c engaging a pattern d carried by the work-table e, is mounted on the end of a lever 2 which is pivotally mounted on another lever 9, the pivotal movements of which are limited by stops 10 and resisted by frictional engagement at one end with a fixed rod 11; this arrangement brings the follower c into a position in advance of that which it would otherwise occupy and it thus starts the reversal action sufficiently in advance to overcome the reversal lag and give the length of travel of the slide required. The work and pattern are mounted on the table e which can receive horizontal feed movements in directions at right-angles and also vertical feed movements, the latter being made at each reversal of the slide f or at other intervals.

Filed: 1955-06-10
Abstract: 774,051. Semi-conductor materials. STANDARD TELEPHONES & CABLES, Ltd. June 10, 1955 [July 6, 1954], No. 16814/55. Class 37. [Also in Group XL (a)] An electroluminescent radiation amplifier comprises a glass plate formed with V-shaped grooves 11 containing photo-conductive material 15 with metal strips 14, 14a running down the apices of the grooves and a series of elemental contacts 13 are formed on the base surface 12 between the grooves. Contiguous with the contact element 13 is a layer 16 of an electroluminescent material and superimposed thereon a plurality of terminal strips 18, 18a which are mutually insulated from each other. The layer 13 comprises a plurality of sets of insulated contact elements (Fig. 4, not shown), the contacts 14 and 14a are connected to the negative and positive poles respectively of a battery 21 and the contacts 18, 18a respectively across the alternating potential source 25. In order that the material 16 shall have a luminescing characteristic dependent on frequency and amplitude of the applied alternating voltage as well as on the D.C. bias, a stratum of polaristor material 29 is interposed between the luminescent material 16 and the contact element 13. This polaristor material may consist of colloidal suspensions of conductive particles in oil or alternatively of conductive or semi-conductive particles in a plastic layer which has been hardened in a strong polarizing electric field. Titanium dioxide is a suitable conductive material and the plastic may be either polystyrene, methyl methacrylate or urea formaldehyde. Alternatively the material 29 may be a ferro-electric material having the property of decreasing capacity with increasing bias. The effects of the polaristor and ferroelectric materials in improving the luminescent response and in giving either positive or negative reproduction are described by reference to Figs. 6 to 8 (not shown). In order that one portion of the photo-conductive layer 11 shall be unaffected by light the glass plate 1 is formed with a lenticular surface with the lens portions opposite that part of the photo-conductive material on which the light image is required to fall.

Title: Integrated optical device associating a waveguide and a photo detector and a method for manufacturing such a device
IPC: H01L31/02
Filed: 1974-04-17
Abstract: 1463159 Photocells THOMSON-CSF 17 April 1974 [20 April 1973] 16868/74 Heading H1K [Also in Division G2] Light is directed to a photosensitive PN junction, formed by diffusion and located at an aperture in a first insulating layer disposed on a flat semi-conductor body, by a light guide comprising a second insulating layer of higher refractive index than the first which extends over said first layer and into or over the aperture therein. In one embodiment, Fig. 1, the second layer 3 terminates in the aperture and electrode connections are provided to the junction-forming regions as shown. In a variant, in which only part of the light passing along the guide is to be fed to the junction, the second layer extends out of the aperture on opposed sides and the top electrode runs normal to the guide. In one modification of this variant a thinner layer of the same material as the first layer is provided in the aperture, its thickness determining the degree of coupling between guide and junction, while in a second a layer of the same thickness as but of higher refractive index than the first and second layers fills the aperture, e.g. this may be lithium diffused or implanted silica if the semi-conductor is silicon. In all cases the junction and electrodes are first formed by conventional diffusion through genetic oxide masking, deposition, and photoetching techniques. Then, after reoxidizing if necessary in the aperture, borosilicate glass is cathode sputtered either overall, or using a mask overlying part of the aperture to give the curved configuration shown in Fig. 1, and patterned by photoetching. To form the second modification the oxide is completely removed, the surface reoxidized, the oxide apertured and electrodes formed, and lithium implanted into the oxide over the junction to increase its Á prior to depositing the glass. The semi-conductor body may include several photosensitive junctions and other components of an integrated circuit.

Filed: 1961-05-10
Abstract: 978,570. Hypodermic syringes. S. MYERSON, and R. L. MYERSON. May 10, 1961, No. 17009/61. Heading A5R. A sterile packaged hypodermic needle for insertion into a needle-receiving passage in a syringe has a sterile sleeve mounted to enclose the syringe entrant end of the needle, both the needle and the sleeve being insertable in the passage. A double-pointed needle 2 has a resilient sleeve 32 tightly slidable on one end. The needle is packaged in a container 24 having a cap. For use, the cap is removed and the container held so that the end of the needle carrying the sleeve is exposed. The exposed end of the needle is then inserted in the forward end of a syringe 4 having gripping jaws 14 and containing a medicament cartridge 20 closed by a pierceable cap 21. The needle is passed through a passage 15 between the jaws and a wider passage 19 until the needle point penetrates a cartridge cap, the sleeve, which may have an end wall over the needle point, being retained between the jaws by projections 43 as the needle is moved towards the cartridge. When the needle has penetrated the cartridge cap, the jaws are tightened against the sleeve and the needle by a threaded cap 12. The jaws may have protuberances (not shown) extending into the passage 15 which, when the jaws are tightened, deform the sleeve and needle slightly. Instead of the projections on the jaws, the sleeve may have a flared portion 34 which engages an enlarged mouth 14a between the jaws to retain the sleeve between the jaws as the needle approaches the cartridge. Alternatively, a cylindrical sleeve (not shown) is moved with the needle as far as the cartridge cap, the outer face of which arrests movement of the sleeve as the needle pierces the cap. The needle-receiving jaws may be omitted and a hub may be secured centrally about the needle for securing the needle to the syringe. In a modification, the syringe has an initially empty cartridge 20 (Fig. 12) and a cylindrical rubber sleeve 98 is mounted on one end of the needle which has a threaded hub 90 for securing to the syringe. The sleeve 98 provides a closure for the cartridge when the needle is applied to the syringe. The sleeve may have a flared flange 210 (Fig. 17) which spaces it and the needle point from the passage 218 into which the needle is inserted.
