Title: Improvements in or relating to machines adapted for inserting fasteners
IPC: A43D71/02
Filed: 1950-08-15
Abstract: 688,304. Nailing. BRITISH UNITED SHOE MACHINERY CO., Ltd. (United Shoe Machinery Corporation). Aug. 15, 1951 [Aug. 15, 1950] , No. 20194/50. Class 89 (iii). In a fastener-inserting machine in which the work is fed step by step past the fastenerinserting mechanism, the work support is raised towards the fastener-inserting mechanism by fluid pressure. In the machine shown which is adapted to insert fibre fasteners as described in Specification 324,682, [Class 89 (iii)], depression of a, treadle 248 first raises a shoe-supporting jack 16 under low fluid pressure to clamp the work lightly against an abutment 22, and then on further depression causes the work to be clamped firmly under high fluid pressure and a clutch 26, 28 to be thrown in to drive the fasteners. Oil from a sump 112 normally passes round a circuit formed by conduit 114, pump 116, conduit 118, passage 120 in a valve block 124, bore 156 in which a jack-operating valve 154 is slidable, port 172 and conduit 174. The valve 154 is actuated by the treadle 248 coupled to a two-armed lever 230. When the treadle is partly depressed, the valve 154 moves downwards to close the port 172 and the fluid returns to the sump through a conduit 166, low-pressure regulator 168, and conduit 170, this low pressure being transmitted through passage 178, valve 192, conduit 214, time delay valve 216, and conduit 110 to a cylinder 106 in which is a piston 104 connected by its rod 102 and a twoarmed lever 74 with the jack 16. When the treadle is fully depressed, the port 164 leading to the conduit 166 and low-pressure regulator 168 is closed and the fluid pressure is controlled by a high-pressure regulator 126 whereby full pressure is applied to the jack. This pressure acting through conduit 182 and piston 190 is sufficient to raise rod 60 against spring 66 to allow engagement of the clutch 26, 28 under the action of its spring 34. The piston 104 is locked against movement by the closure of valves 192, 292 preventing flow of fluid to and from the cylinder 106. A rod 92 operated by a cam 98 on shaft 24 controls the valves 192, 292 through levers 224, 306 and lowers the jack 16 slightly during feed of the work by the usual awl through a lever 86, link 84 and two-armed lever 74. Time delay valve 216 comprising needle valve 280 and spring pressed valves 270, 274, 278 prevents rapid lowering of the jack 16 in case the treadle 248 is released slowly. Part depression of the treadle is indicated by a spring-pressed washer 262 on rod 240 engaging an abutment 256.

Title: An electrical signalling system using asymmetrical direct current signalling for use in telephone exchange systems
IPC: H04Q3/00
Filed: 1965-05-14
Abstract: 1,086,775. Automatic exchange systems. INTERNATIONAL STANDARD ELECTRIC CORPORATION. May 14, 1965 [May 21, 1964], No. 20430/65. Heading H4K. Keysenders, which transmit codes according to whether the a and/or b wires are earthed direct or with resistance and/or with rectifiers and a test for the codes is made from the exchange by first applying an interrogating current in one direction - U and then applying interrogating current in the opposite direction + U, have a set of keys 1 to 0 for sending directory digital information and a key or keys for setting up special service conditions such as call transfer or toll operator assistance, a common receiver WE at the exchange being seized to interpret directory digital information codes but the link circuit VS interpreting special service codes. With the code shown in Fig. 2 directory digit keys 1 to 0 produce codes which have both a and b conductors grounded, with or without resistance, when presented with normal feed current from the link circuit VS. This fact can be used to actuate a detector WJ in the link circuit VS to seize a directory digit receiver WE. Special digit keys, of which there are two, produce codes having the a wire and the b wire earthed, respectively. A detector Sk in the link circuit responds to these codes to connect special service circuits appropriate to the code. With the code shown in Fig. 3 only one special service key is catered for and this produces earth on the b wire providing detection in the link circuit VS by operation of Sk. The directory digit codes 1 to 0 have the a wire earthed for codes 6 to 0 and both a and b wires earthed for codes 1 to 5. Detection of each group of codes can be made by the detector Wj so that the seizure of the common receiver WE can be selectively for one group or the other. Detection of codes within each group by the receiver can be achieved by a single interrogation pulse in the reverse current direction to the feed current from link VS, thereby reducing the time of employment of the receiver.

Patent GB-490161-A (GB)
Title: Improvements in expanded rubber
IPC: C08J9/00
Filed: 1937-07-24
Abstract: Expanded rubber is prepared according to the general process described in Specification 358,967 wherein inert gas is injected into the rubber dough under high pressure and at a temperature sufficiently elevated to cause partial vulcanization, the dough then being allowed to expand and finally being completely vulcanized by further heat and pressure treatment, but with the modification that the vessel containing the rubber dough is evacuated before the initial heat and pressure treatment.  In an example, the dough is prepared as described in U.S.A. Specification 2,067,020 by masticating rubber sheets while introducing fluxes, tougheners, and a vulcanizer, allowing the product to cool off and rest for some time between each addition, and finally squeezing all air from it by further mastication.  The dough is introduced into an autoclave which is then evacuated to a pressure of 5 inches of mercury, after which an inert gas such as nitrogen, helium, or ammonia is introduced at a pressure from 150 to 200 atmospheres, and the autoclave heated by a steam jacket through which passes steam at about 8 pounds per square inch.  The autoclave is cooled, the pressure released and the rubber allowed to expand.  Subsequently vulcanization and expansion is completed by a further heat and pressure treatment.  It is stated that the completion of the vulcanization should take place within about 48 hours since otherwise there is a tendency for gas to escape from the partially vulcanized rubber.

Abstract: 441,143. Batteries; battery lamps; two-part couplings. CRAMPIN, H., 385, Grimsby Road, Cleethorpes, Lincolnshire. July 16, 1934, No. 20752. [Classes 38 (i) and 53] [See also Group XI] An electric lantern for use on buoys comprises an accumulator G within a casing D on the cover of which are two bulbs L enclosed in globes K, the switch B on the cover and the corresponding terminal C of the accumulator being so arranged that contact can only be made when the accumulator is placed in the casing the right way round. When this is done the gas vent A of the accumulator, which is arranged towards one side as shown in plan in Fig. 1, is located near the side of the casing adjacent the staff F which carries the lantern. This side of the casing is at a higher level than the opposite side as the weight of the accumulator causes the staff to lean out of the vertical position, and the vent being on the higher side, acid is less liable to be shaken out of the accumulator through the vent. In order further to ensure that the accumulator is placed in the right position in the casing the globes K are sufficiently large to make it difficult to get the hand between them to reach the switch B. The switch is therefore placed as shown in Fig. 1 away from the staff F, and the battery terminal C is placed to one side which makes it necessary to place the accumulator in the casing the right way round. The terminals are provided with projecting lugs Z for the attachment of clips for charging purposes.
