Title: Improvements in and relating to photographic roll-film cameras
IPC: G03B17/42
Filed: 1951-05-11
Abstract: 713,534. Photographic roll-film cameras. VOIGTLANDER & SOHN AKT.-GES. May 11, 1951 [May 11, 1950], No. 11181/51. Class 98(1) A combination preparing device for a photographic roll-film camera comprises a depressible plunger and a screw spindle rotated thereby in which within its stroke cycle the plunger actuates means which control a film pressure plate and a shutter setting means, and the spindle rotated by the plunger is coupled with one or more driving members through which by rotation of the spindle, the film is wound, and an exposure counter and a lock against the winding of unexposed film are actuated. As shown, a hollow plunger 6 is slidable in a tube 15 formed between the top wall 100 of the camera and an intermediate wall, the plunger being urged outward by a spring 18. The bottom 11 of the plunger is slotted to engage a bar 12, helically twisted at 14, and a projection 17 of the plunger moves in a longitudinal slot 16 of the tube 15. When the plunger is depressed, during the first part of the movement, before the helix 14 is reached, projection 17 operates mechanism for raising a film presser plate, and for setting the shutter. As movement continues, engagement of the helix with the slot rotates bar 12 through one revolution. An assembly comprising an eccentric disc 29, a gear wheel 27 meshing with a film-winding pinion 31, a collar 28, and an annular cam 26, is loosely mounted on a shaft-like extension of bar 12, and urged downwards by a spring 30 so that collar 28 rests on a pin 22 of the shaft. As the shaft rotates, pin 22 bearing on the steep face of cam 26 rotates the gear 27 one revolution. This rotates pinion 31 which operates the film-winding mechanism; e.g. shaft 38 of pinion 31 is fast with the film take-up spool 32. Eccentric 29 also rotates and rocks a lever 51 carrying a pawl 54 which moves an exposure-counter 56 by one step. During the return movement of the plunger 6 under the action of spring 18, the shaft carrying pin 22 rotates in the opposite direction and engages cam 26 to move collar 28 and the parts attached thereto upwards along the shaft. During this movement gear 27 remains in mesh with pinion 31 and does not rotate. When collar 28 reaches the top of its movement, an upturned lug 48 of a bar 49 is moved under it by action of a spring 58 and prevents it from moving down again when pin 22 reaches the end of the cam, until an exposure has been made. The shutter is released by means of a plunger 7, the end of which bears on the inclined end 60 of bar 49, drawing it to the left. Lug 48 is then withdrawn, allowing collar 28 to move down into contact with pin 22. When plunger 7 is released the bar moves to the right until the side of lug 49 abuts the collar 28. Thus once the film has been wound and the shutter set, depressing plunger 6 has no effect until the shutter has been released. Specification 711,221 is referred to.

IPC: C11D13/18
Filed: 1946-04-30
Abstract: A process for producing an air- or other gas-containing soap comprises forcing soap through small holes and simultaneously introducing particles or bubbles of air or other gas into the soap passing through said holes, thereby forming shreds of the soap containing the air or other gas, and mechanically compacting said shreds while retaining interspersed air or other gas within the soap mass.  If desired, the mechanically compacted product may be extruded, for example in bar form.  The process is particularly adapted for the treatment of milled soap to produce air- or other gas-containing floating milled soap.  Perfumes and builders may be incorporated in the soap to be aerated.  The process may be carried out in the apparatus of Specification 646,008.  The Specification as open to inspection under Sect. 91 refers to aerated soap, which may have sufficient air distributed therein to cause it to float, and which may have a moisture content between 18 and 42 per cent, and also refers to certain processes for the production of such aerated soap and for its extrusion.  This subject-matter does not appear in the Specification as accepted.

Patent GB-480150-A (GB)
Title: Improvements in or relating to printing telegraph systems
IPC: H03M13/51
Filed: 1937-04-22
Abstract: 480,150. Type - printing telegraphy. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. April 22, 1937, No. 11570. Convention date, May 7, 1936. [Class 40 (iii)] The system employs a multiunit equal-interval code in which the ratio between marking and spacing elements is the same for each character, and the receiving arrangements are such that a character is printed only if the received signal consists of the fixed ratio of elements. If an incorrect ratio is received, an " error " character may be printed. The system thus prevents printing in the case of signals mutilated by fading or interference. The code may be of 7 units with 3 (or 4) marking elements providing 35 combinations and using case shift, or it may comprise 8 units of which 3 (or 4) are marking elements providing 56 (or 70) combinations used without case shift. The receiver, Fig. 3, comprises code bars 5 and selector bars 6, one of which can drop into aligned notches 7 in the bars 5 only when the fixed number (3 as shown) of code bars have been shifted to the left. An " error " character bar 22 is selected, if more or less than 3 bars 5 have been shifted, by dropping into a notch N in a bar 20 which is drawn to the left (as shown) to prevent the dropping when a notch in cam 17 comes opposite a projection 19 on bar 20 after movement of 3 bars 5. The shaft of cam 17 is rotated by spring 14 under control of escapement 8, 10 actuated by bar 12 each time a bar 5 is moved to the left. The cam-shaft 9 is restored to normal after character selection by a rack 25 moved to the left by the printer driving mechanism and engaging pinion 22 which drives the shaft through spring 26, a pin 27 on the shaft engaging a stop 28 when normal is reached. The pin 27 by engaging abutment 35 prevents the shaft from being moved more than 4 steps, due to an incorrect signal. When rack 25 moves to the left, pin 29 rides above guide 30 until it reaches spring 31 which deflects the pin so that on the return stroke with the pin beneath the guide, the rack 25 is free of pinion 22, the rack being raised again by a spring 34. In a modification, the escapement shaft 9 and cam 17 are replaced by a relay counting chain which receives an impulse each time a bar 5 is moved to the left. After 3 impulses have been received, a magnet is operated to draw bar 20 to the left to prevent selection of the " error " character bar 22, but if more than 3 impulses are received, the magnet is de-energized to permit selection of bar 22. In this modification, the restoring bar 25 opens the holding circuit of the relay chain.
Patent GB-513606-A (GB)
Title: Improvements in or relating to counting apparatus for counting a number of electrical impulses
IPC: H03K23/74
Filed: 1938-04-14
Abstract: 513,606. Counting electrical impulses. BRITISH TABULATING MACHINE CO., Ltd. April 1.4, 1938, No. 11583. Convention date, April 15, 1.937. [Class 106 (i)] Apparatus for counting electrical impulses comprises a chain of 'electromagnetic relays arranged to become energised in succession, one in response to each of said impulses, the last to be energised actuating a counter and being maintained energised by a holding circuit for a substantial part of the time required for the next energisation of the relays in the chain, thus providing sufficient time to actuate the counter. The invention is described as applied to a Hollerith horizontal sorting machine and enables an electricallyoperated units counter of usual design to be used for counting the cards as they pass rapidly through the machine. For this purpose, the operating magnet for the counter is energised only as each tenth or hundredth card passes, and remains energised during the passage of the succeeding seven or seventy cards, respectively, to provide sufficient time for it to actuate the counter. As each card passes, a relay 39, Fig. 1, is energised by the usual card lever 40 or by a commutator 38 driven by the machine. The resultant impulses energise units relays 1-10, Fig. 2, seriatim, each relay as it is energised establishing its own holding circuit and preparing a circuit to the next relay. The energisation of relay 10 makes a circuit through a magnet 71 to operate the counter and simultaneously de-energises all the relays 1-9, the relay 10 remaining energised until its holding circuit is broken by the next energisation of relay 7. If this period is insufficient to permit a proper actuation of the counter, a switch 70 is adjusted to direct the impulses from units relay 10 to a series of tens relays 101-110, Fig. 1, identical with the units relays. The last tens relay 110 is connected through a switch 82 to the counteractuating magnet 71 and is de-energised by the relay 107 after seventy impulses. To enable the units digit of the number of cards to be ascertained at the end of an operation, numbered lamps, 78, Fig. 2, are associated with the units relays 1-10, the arrangement being such that, upon the depression of a key 77, the lamp associated with the last relay to be energised is illuminated. A similar series of lamps is controlled by the tens relays to give an indication of the tens digit when the counter is used to register hundreds. Prior to the initiation of an operation, any relays left energised at the end of the preceding operation are de-energised by depression of a key 90, Fig. 1.
