Title: Shoring frame for use in mines
IPC: E21D11/34
Filed: 1929-10-11
Abstract: 345,196. Shoring ; mine roof supports. QUEENS, H., 350, Bottroperstrasse, Gladbeck, Westphalia, Germany. Oct. 11, 1929, No. 30860. [Class 20 (ii).] The members of a shoring frame for use in mines are rendered yieldable by means of connecting members which permit relative movement of the frame members and which comprise a pair of wedge members which coact with an interposed steel spring bent in C-shape. According to one construction, a shoring frame-leg b, Fig. 1, is yieidably connected with a prop a and a caprail k by a prop-shoe c and a cap-joint member l, respectively. The prop-shoe is formed with a hook c<3> by which it is suspended from the prop a and, as shown in section in Fig. 4, has two claws c<1> which are adapted to embrace the flanges of the leg b. In the space enclosed between the prop-shoe and the leg b are disposed a wedge d, a nose-wedge e and a steel C-shaped spring g. The wedge d, which tapers towards its lower end, is connected to the leg b by a hook h and has a claw i which engages with the prop a. The nose-wedge e is secured to the propshoe and is adapted to prevent the longitudinal displacement of the steel spring. In operation, when the frame is subjected to heavy pressure, the leg b slides relatively to the prop a and carries with it the wedge d which compresses the spring g. The construction of the cap-joint member l is substantially the same as that of the prop-shoe. In action, the member l slides, with lateral movement of the leg b, towards the centre of the gallery, the spring insert being compressed by the wedge m. A complete frame comprising foot- and base-members and two side uprights may be constructed with joint members such as that shown at l between the contiguous ends of the frame parts.

Title: Improvement in rubber tubing or the like and process and apparatus of making the same
IPC: D02G3/32
Filed: 1935-04-18
Abstract: 448,605. Rubber tubing. ALDERFER, S. W., Ely Road, Fairlawn, Akron. Ohio, U.S.A. April 18, 1935. No. 30908. Convention date, Nov. 7, 1934. Divided application. [Class 99 (ii)] [See also Group V] Rubber tubing, including flattened tubing and tape with a tubular selvage edge, is made by forming a tape from latex and rolling it while in motion and under tension into tubular form so that the edges of the tape form a seam. The latex may be natural or artificial and vulcanized or not. In an apparatus for forming the tubing, a tape of rubber 2 is passed under tension under a roller 3 and over a flanged roller 4, the tape being thus rolled into a tube. If the tape is led out from roller 4 in a straight line a full tube is obtained, while if it is bent round the roller, a flattened tube, Fig. 6, is obtained. If the roller 4 is adjusted so that the base of the flange 5 is just inside the near edge of the tape, a tape with a rolled selvage edge will be produced, Fig. 7, or by using two flanges a tape with double selvage edges may be obtained.

Title: Transistor amplifier circuits
IPC: H03F3/343
Filed: 1962-08-14
Abstract: 975,688. Transistor amplifying circuits. BENDIX CORPORATION. Aug. 14, 1962 [Aug. 21, 1961], No. 31214/62. Heading H3T. In a transistor D.C. amplifier for use in an automobile radio comprising three cascaded transistors 16, 38, 58 alternately of opposite conductivity types, ignition noises from the power supply are suppressed by means of a filter network 22, 24, 26, 28 connected between a terminal 20 of the supply A+ and the respective emitters of the transistors. The gain of the amplifier is maintained constant by negative feedback over a path via resistor 68 from a tapping on the output load 62 to the base of input transistor 16 which base is biased by means of resistors 30, 32, 34 a capacitor 35 being connected as shown to prevent audiofrequencies from subsequent stages from circulating in the base-emitter path of transistor 16. By using a self-heating resistor 22 having a high positive temperature coefficient of resistance and a low coefficient of thermal conductivity further negative feedback is applied to the output stage transistor 58 and stabilization against temperature variations is achieved by means of thermistor 66. In the circuit of Fig. 2 (not shown), by-pass capacitor 44 is omitted and the value of resistor 42 is reduced to provide an increase in the D.C. loop gain.
Patent GB-715739-A (GB)
Title: Improvements in or relating to the preparation of supported platinum metal catalysts
IPC: B01J21/08
Filed: 1952-12-09
Abstract: Benzene is formed by the dehydroisomerization of methylcyclopentane in the presence of a catalyst comprising a platinum metal on an acid carrier containing silica and/or alumina, which has been prepared by treating the carrier in the neutralized state with a solution of a compound of a platinum metal having a pH above 3.5, drying the product and removing the agent by which the carrier was neutralized. Reaction conditions p  given are a temperature of 475 DEG  C., a pressure of 21 atmospheres, a liquid hourly space velocity of 16.6, and a hydrogen to hydrocarbon mol. ratio of 5:1.ALSO:Catalyst comprising a platinum metal on an acid carrier containing silica and/or alumina is prepared by treating the carrier in a neutralised state with a solution of a compound of a platinum metal having a pH above 3.5, drying the product, and removing the agent by which the carrier was neutralized.  The carrier may be prepared by neutralizing a clay-type cracking catalyst or an acid silica-alumina hydrogel obtained by reacting sodium silicate with an acid and an aluminium salt; alternatively the carrier may be formed by precipitating a hydrogel of silica and/or alumina under neutral, alkaline, or only slightly acid conditions.  Suitable neutralizing agents are ammonia and lower amines, which are subsequently removed by calcination or by heating in a flushing gas or a partial vacuum; alkali metal or alkaline earth metal hydroxides, carbonates, and bicarbonates may also be used and are removed by treatment with dilute acid or an acid-acting salt, e.g. nitric acid, ammonium chloride, ammonium sulphate, aluminium sulphate and aluminium nitrate.  When a non-volatile alkali is used as the neutralizing agent, a portion of the alkali may be left in the catalyst to reduce excessive activity. Suitable impregnating agents are aqueous solutions of [Pt (NH3) 6]Cl2, [Pt (NH3)4](OH)2, [RU(NH3)4]CI2, [Pt (NH2)4](NO3)2.  [Pd (NH3)4]Cl2.  [Rh(NH3)6]Cl3, [OSO2(NH3)2] Cl2, [lr(NH3)4]Cl2, and [Ir (NH3)6]Cl3.  The illegible data catalyst may contain 0.01-1 per cent. or more of platinum metal and may be reduced and partially sulphided before use.  In an example, a neutral silica-alumina hydrogel is precipitated, aged, washed, dried, and then treated with ammonium nitrate solution to remove sodium ions.  After washing and drying, the gel is soaked in a neutral solution of tetramminoplatinous chloride, washed, dried and calcined to remove ammonia.  The catalyst is treated with hydrogen to reduce the platinum to the metallic state and then used for the dehydroisomerisation of methylcyclopentane to benzene (see Group IV (b)).

[Class 80(ii)]' Locking means for a splined thrust collar 17 of the kind which is turnable in a groove 19 in a splined shaft 11 to bring its splines end on to the shaft splines comprises an axial key 21 engaging between two adjacent splines of the collar and shaft and located axially in one or both directions by a circlip 25 or circlips engaging a light annular groove or grooves in the shaft splines. The collar 17 is shown as acting to locate a gear wheel 14 against axial movement to the left. The gear 14 is either rotatably mounted on a bush 13 splined to the shaft 11, or, according to the Provisional Specification, directly splined on the shaft, and a spline of the bush or wheel is cut away to accomodate the key and locate it axially in one direction. The edges of the key 21 are chamfered, Fig. 2 (not shown), so that the key completely fills the gap between splines of truncated triangular shape, and two diametrically opposed keys 21 may be used. Where thrust collars are employed on both sides of the gear to locate it against axial movement in either direction, Fig. 4 (not shown), a single key or keys passing completely through the gear or bush locates both collars. In this case the key does not project beyond the collars, and is located by circlips at each end abutting the outer faces of the collars.
