Title: Improvements in or relating to paper feed mechanism for tabulating or other printing machines
Filed: 1929-04-05
Abstract: 328,413. Accounting & Tabulating Corporation of Great Britain, Ltd., Thomas, A., and English, F. G. S. April 5, 1929. Web-feeding arrangements; platen-rotation for blanking.-In tabulating and like machines, blanking-feed mechanism independent of the line-spacing mechanism co-operates with the web after it has passed the platen and is automatically operated after a predetermined number of operations of the machine to pull the web a predetermined distance over the platen; the mechanism may also be operated automatically as an incident to total-taking. The machine shown in Fig. 1 includes the device described in Specification 328,319, [Class 106 (i), Calculating &c.], for stopping the machine after a predetermined number of cycles, and the blanking- feed mechanism for the web B described in Specification 328,282, a modified gripper-operating connection also being described. The stopping-device comprises a nut which.is traversed by a pawl 1 and ratchet-wheel 11 and is returned when a cam on the nut permits a reciprocating member 10 to release the pawl and a detent 4. The blanking-feed mechanism comprises a reciprocating gripper 27 connected by a link 29 to a rocking arm 33 operated by a disc 22 which is coupled at each total-taking operation to a driving-shaft by means controlled by a rocking arm 19 operated by the total link 26. The gripper shaft 28 is connected to toggle links 30, 31, the link 31 having a stationary pivot 32 and being connected to the link 29. The arm 19 is now pivotally connected to a bar 18 arranged in a gate G having notches G<1> - - G<4>, Fig. 3. The bar is connected by a link 23 to a finger 24 pivoted on the arm and co-operating with a pin 25 on the link 26. A slotted member 18<a> on the bar engages a finger 17<a> on a bell-crank 17 connected by linkage 16 - - 12 to a lever 7 carrying a latch 5 which co-operates with an arm on the pawl 1, and has a pin co-operating with the member 10. When the bar 18 is in the notch G' blanking-feed is initiated by a link 26 as an incident to total-taking, the latch 5 simultaneously releasing the pawl 1 and detent 4 and permitting return of the stopping-device; or if the predetermined number of cycles is effected before totaltaking, the member 10 displaces the latch, and the bell-crank 17 displaces the bar 18 to initiate total-taking. When the bar is in the notch G<2>, a pin on the lever 7 lifts the latch 5, the bar is released from the bell-crank, and blanking-feed is initiated only by the total link. When the bar is in the notch G<3>, the finger 24 is moved out of the patch of the pin 25, and blanking-feed is initiated only by the stopping-device. When the bar is in the notch G<4>, the blanking-feed mechanism is disconnected, a notch 18<c> in the bar being engaged with the notch G<4> to maintain disconnection. The machine may be provided with a winding-roller for the web, the spring- operated winding-roller 34 described in Specification 328,414 being preferably employed.

Title: Improved photographic process and light-sensitive elements therefor
IPC: G03C5/10
Filed: 1941-08-20
Abstract: 550,785. Photographic reflex-printing processes. KODAK, Ltd., STEVENS, G. W. W., MARRIAGE, A., and SELMAN, R. F. W. Aug. 20, 1941, No. 10635. [Class 98 (ii)] In a reflex-printing process using a sensitive silver salt emulsion, the latent image is developed to silver, which is dissolved out, and a positive image containing silver is thereupon developed. The layer may be hardened in the places free from the negative silver image and those portions of the image containing silver dissolved. The material may comprise a sensitive silver salt emulsion layer behind which has been coated a less sensitive silver salt emulsion layer, the first emulsion layer being exposed during the reflexcopying process by means of light first passing through the less sensitive layer, a negative image being developed in the first emulsion layer, printed on to the second layer, and developed, and the first image being removed, e.g. by removing the whole emulsion layer, either (a) by wet or dry stripping ; (b) by incorporating in the more sensitive layer a substance (calcium carbonate) effecting disintegration when treated with a suitable bath (an acid) ; or (c) hardening the less sensitive layer so that the more sensitive layer may be removed by hot water or by an alkali thiocyanate. The less sensitive layer may be hardened with a hydroxyaldehyde or an open chain diketone having oxygen atoms attached to adjacent carbon atoms or by moist incubation in the presence of the hardening agent. The first layer may be removed prior to development of the latent positive image. The negative image may be developed to silver and the positive image colour developed to a silver plus dye (yellow, orange, black, or grey) image, all silver from both images being then dissolved out. The more sensitive layer may be removed by mechanical abrasion. The negative image need not be fixed before printing. The less sensitive layer may be the light-diffusing layer of Specification 529,041. A thin isolating layer may be arranged between two emulsion layers. The less sensitive emulsion may be hardened and the negative image developed in the outer emulsion by a non- tanning developer. The material is given a diffuse second exposure and redeveloped in a tanning developer followed by washing off the untanned emulsion with hot water or an alkali thiocyanate. Specifications 444,289, 463,427, 479,419, 527,332, 528,433, 548,672 and 549,371 also are referred to.

Title: Shock absorbers
IPC: F16F9/19
Filed: 1965-03-15
Abstract: 1,042,094. Springs &c. FORD MOTOR CO. Ltd. March 15, 1965 [March 21, 1964], No. 10822/65. Heading F2S. A motor vehicle telescopic shock absorber, the damping force Pd is less in jounce than in rebound Pz when the relative velocity between the telescoping parts is below a critical velocity V 1 , but above this critical value the damping force is greater in jounce than in rebound. In a shock-absorber, Fig. 1 (not shown), at low piston speeds, during jounce, hydraulic fluid passes through openings 17 in the piston 2 to lift a control valve 18 against the action of a spring 19 so that fluid can pass from the lower 1b to the upper la cylinder compartment and through an opening 13 in the cylinder wall 1 to an annular chamber 20 which communicates, through a port 21 and a throttled passage 22, with an annular reservoir 5. Up to piston speeds of V 1 , Fig. 2, the damping force is relatively low, however, at this velocity, the increased speed causes a back pressure at the opening 13 so that the damping force rapidly increases as indicated at 33. At low piston speeds during rebound, a relatively strong spring 16 maintains a valve plate 15 in closing relationship with orifices 14 through the piston 2, the damping force, up to the velocity V 1 , due to passage of fluid through the opening 13 being greater than the corresponding damping force during jounce. At piston velocities greater than V 1  the valve plate 15 opens, and the rebound characteristic Pz flattens considerably at 31. A valve 11 controls flow of fluid from the reservoir 5 into the cylinder compartment 1b

Abstract: 1,095,387. Semi-conductor encapsulation. SIEMENS A.G. March 9, 1966 [March 11, 1965], No. 10267/66. Heading H1K. Semi-conductor devices are encapsulated in hardened inorganic cements. Fig. 1 (not shown) represents a silicon planar transistor which has been encapsulated by dipping or coating with a concentrated aqueous solution of magnesium chloride containing suspended magnesia which had previously been strongly heated and allowing this pasty mixture to harden. In the remaining embodiment three wires are drawn through holes in the base of a mould 5, a transistor is alloyed to the central wire, leads are connected between the transistor and the outer wires, and a slurry or suspension of cement-forming material cast around the transistor. Suitable compositions which harden in the presence of moisture are mixtures of magnesia and magnesium chloride, of zinc oxide and zinc chloride, of zinc oxide and zinc phosphate, of alumina and silica, and of zirconia and silica. When the cement has hardened the transistor is separated from the mould and a further transistor placed therein and encapsulated. This process produces a chain of encapsulated transistors disposed at intervals along the wires which are then cut to obtain the individual devices.

Filed: 1919-05-08
Abstract: 149,402. Daubenspeck, H. C., and Winder, S. E. May R. 1919. Blowing.-A device for transferring automatically the parisons from the parison moulds to the finishing-moulds of a bottle-making machine consists of a pair of jaws swinging horizontally between the two sets of moulds and closing as they descend on the parison mould, and opening when they descend on the blow mould. A second pair of jaws is used to prevent the parison from swing- ing. The device may also be used for taking-off finished articles from the machine or from a press. The device consists of a pair of jaws c pivoted to a bracket d, which oscillates horizontally about, and reciprocates vertically on a spindle e, the movements of the bracket being produced by cams as a driving-shaft v<4>, Fig. 2. The jaws c are operated by a locking-lever f, which is tilted one way or another by pins g, g<1> that strike against some fixed part each time the bracket descends. The second pair of jaws i, which steady the parison, are pivoted to a plate s that oscillates horizontally with the bracket d, but does not rise and fall. The jaws are closed by a spring j , Fig. 1, and are opened as the bracket descends by wedge-like fingers k, Fig. 2, secured to the bracket. These jaws fit loosely around the parison but prevent it from swing- ing during transfer. In use, the bracket d in its raised position swings over a parison mould a<1>, Fig. 1, and descends, the fingers k opening the jaws j so that the jaws c can pass between them. The pin g then strikes the mould and closes the jaws c about the neck of the parison. The bracket then rises, lifts the parison, carries it above a blow-mould b<1>, and finally moves downwards. The pin g<1> striking against the mould or some fixed part, opens the jaws c and release the parison. The jaws then rise and move back to the parison moulds. A similar device, consisting of jaws l, Fig. 1, pivoted to a swinging bracket n, may be used to take the finished article from the blowmould and deposit it on a table m.
