Title: Spot-type disc brake
IPC: F16D65/18
Filed: 1970-11-19
Abstract: 1,260,789. Spot-type disc brakes; hydraulic actuator mounting; preventing rattle. ALFRED TEVES G.m.b.H. 19 Nov., 1970 [26 Nov., 1969], No. 54994/70. Heading F2E. A non-rotating brake carrier 2 supports a closed yoke frame 3 which embraces the edge of rotatable disc 1 and transmits actuating forces; a central opening of the yoke frame 3 accommodates an actuating appliance 4, 7 (as shown, a cylinder and piston) which has a reinforced part 10 at the end near the brake disc, which part is fixed between the arms 3<SP>1</SP> of the yoke frame extending over the brake disc 1; the actuating appliance is kept in place by the pressure of those arms upon the reinforced part; the forces produced during braking are transmitted from the actuating appliance to the frame arms through faces on the reinforced part 10 and the frame which abut on the side of the reinforced part remote from the disc. As shown, the ends of the front face 13 of the reinforced part 10 abut against projections 14, 15 of the two arms 3<SP>1</SP> of the yoke frame 3 to transmit braking forces. Also as shown, the distance between the end faces 11, 12 of the reinforced part 10 is chosen to be greater than the spacing between the corresponding surfaces of the arms 3<SP>1</SP> against which they engage; thus, when the actuating appliance is in position, the part 10 is in compression, and the "retaining tension " in the yoke frame 3 is thereby produced. Preferably, the brake cylinder 4 has projections 8 which embrace the frame and slots 9 which engage the frame; the cylinder can be inserted into its position from the centre of the frame. As shown, the yoke frame 3 is slidable on the brake carrier 2 in a direction parallel to the disc axis. The carrier 2 has recesses to accommodate brake pads 5, 6. The manner of attachment of the cylinder 4 prevents the brake from rattling. As shown, the reinforced part 10 is located so close to the part of the frame 3 which is guided on the carrier 2 that deformation of the yoke frame, under stress, in the region of the guiding parts is slight.

Patent GB-588868-A (GB)
Abstract: 588,868. Filtering oil. ABBEY, A. (Briggs Clarifier Co.) Feb. 15, 1945, No. 3869. [Class 46] [Also in Group XXXIV] A lubricating system for a dry-sump engine comprises an oil storage tank connected with the delivery side of a scavenger pump and provided with strainers and filters for removing coarser and finer contaminents, respectively, from the oil before delivery to a reservoir in the tank, independent discharge means being associated respectively with the strainers and filters and communicating independently of each other with the reservoir. As shown in Fig. 13, the crank case E of an engine is connected by a conduit F to a scavenger pump which withdraws oil from the crank case and delivers it to a purifier H. The purified oil is drawn through a pipe I by a pressure pump D and forced through a conduit J and a cooler K to the crank case. The purifier comprises a tank 1, Figs. 2 and 3, divided by a wall 2 into an oil reservoir 4 and a filter chamber 3 containing strainers 9 and filters 11. Oil is fed to the tank through a pipe 35 and may flow through a byepass valve 36 to the reservoir or through a pipe 37 and an apertured pipe 38 to the filter chamber. Oil from the filters 11 is discharged through pipes 33 on to screens 7 in the reservoir. The oil passing through each pair of strainers 9 'enters a chamber 15, Fig. 4, provided with a valve 16 which opens under light pressure allowing the oil to discharge on to a screen in the reservoir. A relief valve 24 allows escape of the oil if the strainers get clogged up. In the arrangement shown in Figs. 6, 7 and 8 strainers 122 are operated in series with filters 135. Oil enters the tank 101 through a pipe 117, and air and foam escape through a filter 114. The oil passes beneath a baffle 109 into a compartment containing the strainers and after passing through the strainers flows down a pipe 129, then through an apertured pipe 133, and then through the filters 135 and is discharged through pipes 143 into the reservoir 103. Relief valves 121 are provided associated with the strainers, and relief valves 132 associated with the filters. The filters and strainers may be bye-passed by the feeding of the oil through pipe 154 instead of pipe 117, the oil passing through a cylindrical screen 158, an apertured tube 156, and an apertured tube 161 into the reservoir 103. The top of the reservoir has pocket screens 147. The filters may comprise two elements secured together by a rod 136 each element consisting of moulded cylindrical blocks of absorbent material and cellulosic wrapping. Each of the strainers 122 is rotatably mounted with respect to scrapers carried by rods 125.

Adhered to the surface of the lower-melting component are particles of an adsorbent material.  Conjugate fibres exemplified have, as the lower-melting -component, polystyrene, polycaproamide, polyethylene or polypropylene. The higher melting component may be either polyethylene terephthalate or polycaproamide. Although side-by-side fibres may be cored the sheath core form is preferred with the sheath and core being concentric and the lower melting component being the sheath.  The conjugate fibres are generally prepared by conventional melt-spinning techniques but in Example 18 polyethylene terephthalate is coated with polystyrene by [passing a tow of polyethylene terephthalate filaments througha solution of polystyrene and then drying the tow.  The adsorbent may be applied to the filaments by sprinkling on to their surface after they have been spun and drawn in air or water. Alternatively the filaments may be passed through a dispersion of the adsorbent. The filaments may be formed into a fabric or moulded into an article before the adsorbent is applied. The adsorbent is then adhered to the lower melting component by heating the material to a temperature between the melting points of the components. Alternatively, the adsorbent may be blown on to the filaments during extrusion when they are at a temperature at which only the lower-melting component is molten.  Adsorbent materials used are carbon black, silica, alumina, manganese, dioxide, cobaltous oxide, cuprous oxide and molecular sieve.

Abstract: 1459185 Card reader; verification GROUP 4 TOTAL SECURITY Ltd 19 Dec 1973 [29 Dec 1972] 60182/72 Headings G4M and G4H [Also in Division E2] A token reader 35 comprises means for producing a varying magnetic field, an array of planar spiral magnetic field detecting coils 1 on a planar support, each able to produce a signal in response to the varying field and therebetween, a token receiving zone 8. The token, in the form of a card 7 having pieces 13 of conductive or magnetic material, e.g. aluminium, is inserted in the zone 8 and actuates a switch 12 to energize windings 6 around identical cores 5. Actuation may be caused by a photo-cell or by a magnetic reading head which senses a magnetic strip on the card 7. In an alternative embodiment, a single winding of, e.g. 5 loops may encircle cores of different lengths all of a printed circuit, to produce uniform fields. Induced currents in the coils 1 (25, seven turn coils) are amplified by transistors 3 and fed to a comparison circuit 14. Here, individual outputs are each compared with individual outputs from a manual keyboard 10, Fig. 5, the comparisons being scrambled, i.e. not in a particular order; the compared signals are passed through an AND gate 16 and then used to control a door lock or a logic gate 17 receiving the output signals from the reader 35 to analysis circuitry 18 for rejecting certain predetermined numbers which may be registered on tokens. This circuitry 18 comprises two sets of matrices of circuits 34, Fig. 7, each comprising a PNP transistor T having its base connected by a resistor R to a - 14 v. supply and via diodes 24 to various input lines from the reader 35, and diodes with resistors 25 to other input lines. The outputs of all transistors are passed to diodes 31, an NPN transistor 28 and an output terminal 33 to operate, e.g. a door. If all the transistors T are non-conductive, then the transistor 28 is non-conductive and the token code is passed to operate the door. If, however, any transistor T is rendered conductive by a particular code output from a given token, the transistor 28 is rendered conductive and a logic O signal is passed to the output thus rejecting the code. Each matrix represents and blocks a set of codes deemed unacceptable. The bases of some of the transistors T may be coupled to terminals of a programmer which can determine specific periods when certain codes are unacceptable. The tokens may have inserts which do not affect the magnetic field but which appear to be similar to the magnetic material to avoid easy forgery.
