Abstract: 773,359. Jaw crushes. KLOCKNERHUMBOLDT-DEUTZ AKT.-GES. Oct. 14, 1955 [Oct. 14, 1954], No. 29349/55. Class 59 A jaw crusher comprising an eccentric drive for the movable crusher jaw 16, wherein the drive includes one or more pressure members between the crusher jaw 16 and an abutment 5, the, or each, pressure member having two oppositely disposed part-cylindrical bearing faces, and wherein the contact between the, or each, pressure member and the co-acting bearing faces. is maintained by a restoring spring, is characterized in that the crusher jaw or the abutment or both is, or art each, provided with a pressure body which forms a bearing face for the coacting part-cylindrical end of the said pressure member, and that the rear wall of the pressure body, opposite to the bearing face, is convex and forms part of a cylinder with an axis perpendicular to the axes of the drive shaft and of the coacting part-cylindrical bearing face respectively, and that the crusher jaw or the abutment or both, as the case may be, is, or are each, provided with a groove adapted to receive the pressure body, the groove being concave and having the same curvature as the rear wall of the pressure body. In the crusher shown in Fig. 1, the crusher jaw 16 is mounted on the swinging shaft 1 by means of resilient sleeves 26 and only the pressure body 8 is provided with a part-cylindrical rear wall 25. When, however, rigid sliding bearings are used instead of the sleeves 26, a pressure body with a part-cylindrical rear wall is likewise provided in the crusher jaw 16. The bearing faces 19 of the pressure member 9 have a common central axis and the surface 27 is also part-cylindrical and preferably has the same radius of curvature as the bearing faces 19. The pressure members 9, 13 are supported by elastic bands 10; alternatively, each pressure member e.g. 9, Fig. 5, may be provided with one or more screws 31 each having a head 30 extending into sleeve 28 of rubber or other resilient material-which is inserted into the corresponding pressure body e.g. 11. Each screw has a hexagonal recess 29 for tightening purposes. In a modification, Fig. 4 (not shown), the jaw crusher has only one pressure member, and the pressure body with part-cylindrical rear wall is provided only in the movable crusher jaw.

Title: Improved phenolic resins and laminated insulating material bonded therewith
IPC: C08G8/28
Filed: 1947-11-06
Abstract: In a process for the production of a resin suitable as bonding agent in laminated insulating materials comprising reacting a phenol or homologue thereof with an aldehyde in the presence of up to 5 per cent by weight of morpholine as a catalyst, the heat-reactive resin so formed is dehydrated in presence of 5 to 15 per cent by weight of a chlordiphenyl containing from 2-4 chlorine atoms per molecule, e.g. Arochlor 1242,.  In an example, equi-molecular amounts of cresylic acid and formalin are heated together in the presence of 0.1 to 1 per cent by weight of morpholine.  The product is dried under vacuum at 50-55 DEG  C., mixed with the chlor-diphenyl and the drying continued.  The product may be used in forming laminates of paper or with glass fibre, which has preferably been de-sized and coated with tetra-ethyl silicate.  In pressing the laminates the platens are preferably coated with paper, "Cellophane," (Registered Trade Mark), natural or synthetic rubber, or resin impregnated cloth to avoid breaking the glass fibres.

Title: Improvements to Systems for the Transmission of Coded Information
IPC: H04L1/00
Filed: 1967-06-27
Abstract: 1,184,225. Digital transmission systems. SOC. D'APPLICATIONS GENERALES D'ELECTRICITE & DE MECANIQUE. 27 June, 1967 [29 June, 1966], No. 29678/67. Heading H4P. A data transmission system in which errors are corrected by repetition employs a code in which each character has a preset number of transitions and has an even number of bits of a given state. In the embodiment described, 5-bit characters from a tape are converted by a diode matrix to 7-bit characters having the form indicated above, the latter characters being transmitted. At the receiver each character is checked that the number of transistions and the parity are correct. If there is no error the character is passed to a tape punch. If there is an error an error-requesting signal is returned to the transmitter where it causes the tape to be reversed by N characters, the local receiver to be blocked for N characters, and a preset character to be transmitted. The tape is now stepped forwards so that the preset character is followed by N characters previously transmitted and then by fresh data. The error signal at the receiver inhibits the tape punch for N+ 1 characters so that only correct data is recorded. The receiver includes means for checking that the preset character is received during the N + 1 inhibit cycle. If it is not received, or if it is received outside the inhibit cycle a further repetition-requesting signal is returned.

Abstract: 1307240 Rotary pressure filter V P ABRAMOV I I TSIRKIN J V GUTIN V L RADUSHKEVICH E L RISENZON and E B KISLY 19 June 1970 [23 June 1969] 29775/70 Heading BID A continuous rotary pressure filter comprises a stationary drum 1 and a rotating housing 5 driven by motor 9. The housing is divided into several filtering cells 6 provided with filtering cloth 20. As each filter cell passes space 10 on the exterior of the drum it is filled with slurry which is fed into space 10 under pressure along pipe 11. The slurry is filtered as the cell rotates around the drum, the filtrate being removed via pipe 7 and distributing head 8 and the filter cake remaining in the cell. When the cell reaches space 12 the cake is washed by water which is fed to this space. A second washing occurs at 13 and then the cake is dried at 14 by compressed air fed through pipe 15. The dried, washed cake falls finally into hopper 3 and is removed by screw 4. Support rollers 16 are provided and are adjustable so that the gap between drum and housing may be altered. Each filter cell is sealed from the next by means of seals 21.

Abstract: 464,842. Making pivoted locking- catches. CHAPMAN, A. W. Oct. 29, 1935, No. 29878. [Class 83 (ii)] [Also in Group XIV] The pivotal locking catch 10 of relatively slidable members 1, 2 such as those of vehicle seats has its transverse pivot pin 13 supported by brackets 4 comprising one or more narrow strips punched or pressed out of the metal of one of the slide members and forming lodgments for the pivot pin with the slide member or between themselves, the brackets also forming guides for the catch. As shown, the strips are punched downwards out of the slidable member 2 secured to the underside of the seat, and are split centrally to form angular parts 9 which are forced upwards from the apex to form a lodgment for the pin. A split pin 15 retains the pin against axial movement. The catch 10 has a nose 11 engaging one of a series of holes 12 in the fixed member 1. Instead of splitting the strips 4 the lodgment may be formed between the strips and the underside of the member 2 and the pin may pass through the vertical side walls of the member 2. The slide members shown engage each other along both longitudinal edges, but the invention may be applied to slide members engaging along one edge only. The strips may be pressed out from the base or the side walls of the slide. Specification 457,495, [Group XIV], is referred to.

Abstract: 1472226 Manufacture of cigarette filters HAUNI-WERKE KORBER & CO KG 9 July 1974 [14 July 1973] 30280/74 Heading A2C In the production of filter rods from crinckled filter tow strip, a stretching force is applied to the closed end of a loop of tow, the force being varied in dependence on some measured property of the. rod being produced thereby controlling the amount of tow in the final rod. As shown, a roller 73 applies the force to the loop of tow 6. The magnitude of the force is varied by a weight 77 which may be moved along an arm 74 which arm carries the roller at one end and is pivoted, at its other end. The weight is moved by a rack and pinion device 78, 81 in response to signals representing the measured value. The arm 74 also carries at its roller end a tap 182 moveable along a potentiometer 181. Changes in the size of the loop are detected by movement of the tap 182 whose tapped voltage controls the operation of an adjusting motor 184 which in turn alters the transmission ratio of a gear unit 186 such that the rate of supply of tow is changed to return the loop to its original size.
