Title: Improvements in or relating to a process, an arrangement, and an apparatus for making diapositives
IPC: G03D15/10
Filed: 1961-09-11
Abstract: 929,420. Mounting transparencies. H. HERMANN. Sept. 11, 1961 [Sept. 17, 1960; July 18, 1961], No. 32509/61. Class 98(2). In a process for the production of a mounted transparency, the transparency and a mask are stuck to side of a cover glass and then covered with a second cover -glass, and a frame having one adhesive side is placed with that side against the other side of the said first cover glass, and projecting flanges on the frame folded over to bind the two cover glasses together. The mask 1 (Fig. 1), with picture window 2, has a strip of adhesive covered by a protective foil 3, and markings 4 for locating the film. The frame 5 has tabs 6 along each edge, and has on one side a permanent coating of adhesive, covered with a protective foil 8. In assembly, foil 3 is removed, and the film placed in position on mask 1. The two are then stuck against one side of a cover glass. The other side of this cover glass is then placed against the adhesive side of the frame 5, from which the protective foil has previously removed. A second cover glass is placed over the mask and film, so that these now lie between the two cover glasses. The tabs 6 are now folded up and over the whole assembly, binding both cover glasses together. Fig. 6 shows a device for facilitating the assembly. It comprises a box-shaped base 17 having a central well portion 18. Within this well portion slides a plate 19 which can be pushed downwards against the action of restoring springs 21. Centrally of plate 19 is a well portion within which is mounted a further plate 24. Plate 24 can be pushed downwards relatively to plate 19 against the action of springs 26. On the upper surface of plate 19 is provided a layer 28 of foam rubber, and on this is laid a square rubber sheet so dimensioned that the edges project somewhat beyond the edges of well 18. A forkshaped stirrup 32 hinged to the base 17 is so designed as to locate opposite corners of the assembly (Fig. 7, not shown). In using the device, the frame 5 is laid on the rubber sheet, so that plate 24 extends into the picture window. The stirrup 32 is hinged downwards into the position shown in full lines in Fig. 6, forming location corners for positioning the first cover glass 12. On this is placed the film and mask 1, and then the second cover glass 13. The stirrup is now hinged back out of the way, and pressure applied to the surface of the assembly. First, plate 24 is pushed into the well of plate 19, and then, as pressure is increased, both plates are pushed together into the well of base 17. In this movement the edges of the rubber sheet 29 projecting beyond the edges of well 18 are turned upwards, taking with them the edges 6 of the frame 5. The turning over of these to bind the two cover glasses together is completed by hand. On releasing the pressure, the assembly is pushed upwards out of the device by the springs, and can be removed.

Abstract: 842,041. Razors. GILLETTE CO. Oct. 25, 1956 [Nov. 1, 1955], No. 32534/56. Class 30 A safety razor comprises a head at one end of a hollow handle and including a guard and upper and lower blade-clamping members, a manually adjustable connection between the guard and the lower blade-clamping member to determine the vertical distance of the blade from the guard, and manually operable means extending through and beyond the handle for bringing the upper bladeclamping member into and out of blade-clamping position. As shown, pivoted cap sections 26 are urged by a prestressed spring 84 to clamp a blade B against edges 44 of a blade-clamping platform 24 and are moved to a partially open position for rinsing or to a fully open position for blade exchange by operation of a pivoted finger piece 38 whereby an axially movable stem 34 and spider 36 move upwards under the influence of a spring 96. The vertical distance of the blade from the guard 30 is varied by raising the platform 24 by rotating a finger knob 54 threaded on an extension 52 of the platform. Indicia 60, 62 mark the position for optimum shave and to maintain the setting and to give an audible signal that adjustment has been made a spring projection carried by the knob 54 engages flutes in the guard extension 48.

Abstract: 340,675. Scavenger's carts. EDWARDS, M. F., Willow Bank, Lostock, Bolton. Oct. 26, 1929, No. 32568. [Class 108 (i).] A cover for the containers of refuse-collecting vehicles comprises two lids A having eyes E through which pass rods C pivoted at D to a fixed part of the container, one rod being pivoted to a cylinder F and the other to a spring-pressed plunger in the cylinder F. Either lid may be opened by lifting it until the lever C is below the position in which the lever C and the cylinder and plunger are in a straight line, when the spring G forces the lid open. When closed the lids form a dust-tight joint under the action of the spring.

Title: Improvements in or relating to central buffer couplings for railway vehicles
IPC: B61G9/24
Filed: 1934-11-14
Abstract: 425,398. Buffing and draw - gear for railway vehicles. KRUPP AKT. - GES., F., Essen, Germany. Nov. 14, 1934, No. 32765. Convention date, Jan. 2. [Class 103 (v)] Relates to central buffer couplings of the kind in which a centralizing spring D for the coupler C<3> is adapted to be compressed by the relative sliding movement which occurs, on displacement of the coupler head, between the coupler shank C and a member G interposed between the shank and the buffing and draw gear. According to the invention the intermediate member G is formed with a number of projections g<2>, g<3>, g<4> which abut against stops h<1>, h<2>, h3 on the buffing and draw gear so as to cause the spring D to be compressed owing either to lateral or vertical displacement of the coupler. In the arrangement shown, the spring D is located in the coupler shank C between a fixed bar F and a key E, which is integral with the intermediate member G and slides within a slot c<2> in the shank C. Between the shank C and draw-bar N is disposed a ball- and-socket joint M, which also has partspherical surfaces co-operating with curved surfaces on a casing H, the latter being provided with the stops h<1>, h<2>, h<3>. The projections g<2>, g<3>, g<4> lie on a circle concentric with the joint M, and all co-operate to compress the spring D when a vertical displacement of the coupler occurs, while one or other of the extreme projections g<2>, g<4> function when a lateral displacement arises. Inclined surfaces h<4>, g<5> are formed on the stops and projections so that, if a rotary or twisting movement is imparted to the coupler, a compression of the spring D again occurs giving rise to a centralizing force. In order to adjust the power of the spring D an abutment J bearing against the forward end f<2> of the bar F is given an initial setting by means of a screw K.

Abstract: 1,046,018. Selective signalling. LORAL ELECTRONICS CORPORATION. Aug. 17, 1964 [Aug. 19, 1963], No. 33471/64. Heading G4H. An analogue to digital converter comprises a core 119 which carries a coil 137, 139 fed by the analogue, a coil 118 which has taps 114-117 which tap off decimally-weighted numbers of turns and are fed by the decimal output of the converter, and a coil 120 which feeds a switching circuit. Initially all the converter's cold cathode indicator tubes 90-92 are at zero. When the analogue is applied at 89 current flows in coil 137 if the analogue is positive, in 139 if negative. Trigger pulses 136<1> now step the hundreds tube 90, gate 96 being enabled by unit 132. An additional current, equivalent to an increment of 100, is supplied from 138 when the hundreds tube is stepping. After each trigger pulse a test pulse 122<1> cuts off transistors 121, 140, 141, the resulting collapse of the flux producing a pulse in coil 120 of polarity dependent on the relative magnitudes of the analogue and digital signals. If the polarity has changed since the last test, unit 132 is stepped, enabling tens counter 91, and unit 138 is taken out of circuit. The hundreds tube now indicates the value of the analogue in that decade, and the tens counter is counted backwards until the next change in sense of m.m.f., whereupon the units counter 92 is operated. Counting ceases after the next change in sense. To reduce the number of taps on coil 118 the resistors connected to the taps may be weighted so that a tap may be shared by more than one decade tube, e.g. as tap 116. The sum or difference of two analogues may be determined by using two analogue coils suitably wound. By changing tappings on coil 118 the order of the value indicated on tubes 90-92 may be changed.
