Filed: 1953-06-11
Abstract: 745,233. Perforating-machines; fur skins or pelts. MESSERLI, H. June 11, 1953 [May 23, 1953], No. 16122/53. Classes 31 (2) and 76. A machine for cutting slits 102-105 in a fur skin or pelt 101 comprises means for clamping the skin &c. above the pins of a pin carrier, and a knife carrier movable in such a manner that the knives, which are in two rows staggered relatively to each other, cut slits in the skin from the hairless side thereof. In the form shown in Fig. 2, the skin is clamped above the pins 122 of a pin carrier 121 by means of clamps 111 co-operating with a table 110. The skin is also clamped by means of cam-operated spring-influenced rollers 126 which press the skin against the faces 123 of members 124. Slits are cut in the skin by means of two staggered rows of knives 128a carried by a camoperated punch 127. To obtain elongated slits, the table 110 is moved in the direction of the arrow during the cutting operation. In a modification, Fig. 3, pins 146 are carried by a roller 145 and slitting knives 141 by a roller 142. The rollers are adapted to be moved apart in order that the skin may be clamped and to be moved in the direction of the arrow during the cutting operation in order that elongated slits may be obtained. A guard 147 and stripper members 148, 149 are provided.

IPC: H01L21/00
Filed: 1965-04-20
Abstract: An epitaxial film of selenium is formed on a single crystal of tellurium by evaporation, decomposition from a vapour, electro-deposition or applying molten selenium.  The tellurium substrate may be pre-heated and, the coating may be subsequently annealed at 90 DEG C.  Further layers of doped selenium or other compounds or elements may be applied to the selenium.

Title: Improvements in coin-freed and similarly operated barriers
Inventor: FOLLOWS WILLIAM BERNARD
IPC: G07F17/14
Filed: 1962-05-01
Abstract: 962, 033. Coin-freed barriers. MYCALEX & T.I.M. Ltd. April 30, 1963 [May 1, 1962], No. 16616/62. Heading G4V. [Also in Division E2] A barrier device to control the passage of persons or objects comprises a barrier 8 which is normally withdrawn and only actuated into an obstructing position if an attempt to pass through is made without the previous insertion of a coin or ticket. In the device shown, a person passing through interrupts in turn three light beams which emanate from lamps 15, 16, 17 housed beneath a rail 6 and normally impinge on their associated photo-electric cells 9, 10, 11 each cell being connected to its respective amplifier 18, 19, 20 and relay 21, 22, 23. When a coin is inserted in a slot 3, it closes a switch 30 to illuminate a green lamp 4, move a deflector 31 for directing subsequently inserted coins down a return shoot 13 and open the circuit associated with the second beam. On passing through the device, only the interruption of the third beam on the cell 11 has any effect and results in extinguishing the lamp 4 and the withdrawal of both the deflector 31 and a slider 35, the latter allowing the coin to fall into a tray 38. If a coin is not inserted, interruption of the second beam on the cell 10 results in illumination of a red lamp 42 and an instruction sign and operates a motor 24 which drives the barrier 8 to a position 8a through a slipping clutch 25; a limit switch 29 stops the motor. On returning to the entrance to the device to insert a coin, the beam on the first cell 9 is interrupted and results in extinguishing the lamp 42 and operating the motor 24 to withdraw the barrier; a limit switch 28 stops the motor. Defective coins are recovered by a pushbutton 14.

In a modification where the fuel nozzle 7 is located in a wing of the throttle valve, the channel 6 communicates at its upper end with the throat of the choke tube 2 through a tube provided with a constriction. Constrictions are also provided in the tube leading into channel 6 on both sides of the tube leading from the choke tube.

Abstract: 1309923 Reciprocating generators MESSESCHMITT-BOLKOW-BLOHM GmbH 9 April 1970 [26 April 1969] 16927/70 Addition to 1184515 Heading H2A [Also in Divisions F2 and F3]  The mechanism of the Specification 1,184,515 is modified by the provision of a latch 24 which is biased by a spring 23 into the position shown in which it engages a part 28 of the second lever 13 to lock the latter. An adjustable stop member 25 on the first lever 12 entrains the latch 24 to release the second lever, in contradistinction to the parent construction in which the equivalent stop (16) entrains the second lever itself. The effect of this is that, whereas in the parent case the second lever is accelerated by the spring 15 and the magnet 19 acting together, in the present case the spring 15 alone accelerates the second lever so that it strikes the magnet armature 18 in a hammer-like manner. This produces a more satisfactory electrical output from the magnet's coil 20.

Fig. 6 shows one arrangement in which the coolant is forced through the heat exchanger by a pump p the motor o of which is controlled by a switch q actuated in accordance with the steam pressure or water temperature at the upper end of the shell. Where a gravity feed for the cooler is employed, a valve is incorporated to enable coolant flow through the cooler to be regulated (Fig. 1, not shown).

A continuous method of making a light-sensitive photographic material comprises first introducing a light-sensitive silver halide emulsion and at least one dye-forming coupler into a mixing zone and thereafter coating the admixed emulsion and coupler on a support, characterized in that a development-inhibitor-releasing (DIR) coupler is admixed into the emulsion and the coupler so that the ratio of the DIR coupler to the dye-forming coupler or couplers on addition to the mixing zone is constant. The DIR coupler may be admixed with the dye-forming couplers before admixture with the silver halide emulsion. The couplers may be non-diffusible, water-insoluble compounds and may be dissolved in a water-insoluble liquid, dispersed in a hydrophilic colloid and admixed with the light-sensitive silver halide emulsion as such a dispersion. The couplers may all be dissolved in a single solvent dispersion. The DIR coupler preferably has a monothio group in its coupling position which upon reaction with oxidized primary, aromatic amine colour developer, forms a diffusible mercaptan development inhibiting compound. Many examples of couplers are given. The materials prepared as above exhibit uniform contrast throughout due to the presence of the DIR coupler.
