Abstract: 1,050,426. Friction clutches. COMPAGNIE DES MACHINES BULL. March 31, 1964 [April 3, 1963; March 5, 1964], No. 13255/64. Heading F2C. [Also in Division H1] A material for a magnetic brake or clutch lining comprises a sintered mixture of P.T.F.E. powder and powder of iron chromized by gas diffusion and containing at most 12% by weight of chromium. Glass fibre may be included in the mixture, and preferably at least 40% by volume of this is chromized iron. Suitable mixtures have a composition-in volumetric percentage-given by 49-55% P.T.F.E., 41-45% chromized iron powder, 10-0% glass fibre. In manufacture iron powder having a size less than 60 is optionally de-oxidized, and placed in the presence of a powdered magnesia/chromium material containing 40%-50% Cr under suitable temperature conditions to become chromized. The chromized iron is " densified " by rotating in a drum, and mixed with the P.T.F.E. and glass fibre at - 40‹ C. The mixture is compressed in a soft iron mould under 400-2000 kg./cm.<SP>2</SP> for 2-3 minutes at 23-25‹ C. The blank so formed is then sintered in or out of the mould. For thin blanks sintering takes place at 380‹ C. for three hours and cooling is at a rate of 20-25‹ C. per hour under a pressure of 200- 800 kg./cm. For thick blanks the blank is, prior to the above treatment, introduced to a temperature of 250‹ C. which is then raised over several hours to 380‹ C. before the above process is continued. The material so formed may be stuck on to a soft iron support by rubber or epoxy resin, and before sticking fluorine atoms may be eliminated from the P.T.F.E. surface by treatment with sodium ions. The support to be lined may be chromized to aid bonding. Alternatively the sintering may take place directly on the support. After bonding the lining may be machined.

Abstract: 1,052,365. Control of D.C. motors. ALLISCHALMERS MANUFACTURING CO. April 30, 1965 [May 7, 1964], No. 18310/65. Heading H2J. Contactor 30 is energized to introduce field-weakening only when switch 45 is closed in the fully-depressed position of accelerator pedal 14, and when centrifugal switch 43, which is mechanically coupled to the shaft of motor 12. has closed its contacts, indicating that the motor has reached a predetermined speed. In addition, selector control 25 must be in an operative position. Dynamic braking is introduced, when the motor is operating forwardly. by releasing pedal 14 to disconnect shunt resistor 35. Control 25 is moved to its reverse position so that contacts 51 open to de-energize relay 53. Subsequent closure of contacts 52 does not energize contactor 36 because the motor is running fast enough to cause speedsensitive switch 48 to remain open. Even closure of contacts 45 will not place the motor in its high-speed range because switch 48 remains open to prevent energization of relay 53. The motor is brought to a low speed before relay 53 is allowd to be energized.

Abstract: 1,052,473. Bending glass sheets. LIBBEYOWENS-FORD GLASS CO. Nov. 27, 1963 [Dec. 3, 1962], No. 46839/63. Heading C1M. Glass sheets moved along a predetermined path from a heating area, through a bending area, where the glass is pressed to desired shape, to a chilling area, are subjected, after bending but before moving on to the chilling area, to streams of cooling fluid directed against opposite surfaces to set the sheet and prevent deformation on moving. The sheet 11 is received from the heating section on to the horizontal run of a conveyer 27 which may be in the form of a wide flexible belt or a series of narrow bands, the belt or bands being held taut by a spring-pressed idler roller 77<SP>1</SP> and being driven by a roller 74<SP>1</SP>. The sheet is conveyed between the upper and lower mould parts 24, 25 and positioned against stops 112. The lower mould part 25 which is of open - ring type, is raised by the cam 53 to press the sheet against the part 24. If a wide belt 27 is used, it is stopped during the pressing operation; alternatively, if narrow bands are used, the surface of the part 25 is slotted. During the lowering of the part 25, cooling air is discharged against the sheet, to set it sufficiently to prevent sagging, from pipes 104 beneath the sheet and from a pipe 107 carried by an arm 108 and traversed across the upper face of the sheet. When the belt returns to normal position or the sheet is deposited on the bands, the conveyer and the first rolls 20 of the tempering section are speeded up, the stops 112 having been withdrawn, to deliver the sheet rapidly, after which they are decelerated and the parts returned to their positions to receive another sheet.

Abstract: 1,238,857. Making disc records. A. LASH. 21 May, 1968 [19 July, 1967], No. 24159/68. Heading G5R. A sound record comprising a record core having on one or both sides a paper disc displaying a picture or the like, and a layer of transparent thermoplastic synthetic resin constituting the playing surface superimposed over the picture surface, is characterized in that the paper disc has a reinforcing disc centrally disposed on its inner surface whereby damage to the paper and spoiling of the picture during record-pressing is avoided. In the simplest forms of the invention, particularly described, each playing layer of the record may be formed by applying a thermoplastic polyvinyl chloride composition, preferably with plasticiser and lubricant components, in the form of a powder to the picture surface of each paper disc, the surface having been pretreated with a tacky adhesive such as a solution of the polyvinyl chloride in methyl ethyl ketone, the powder being coalesced to a transparent layer of sufficient thickness (to accommodate the playing grooves), by heat and pressure in the record press; alternatively the playing layer may be formed by applying a thick glaze of cellulose acetate to the picture surface prior to pressing. A wafer of polyvinyl chloride may be interposed between each picture-bearing paper disc and its corresponding reinforcing disc to secure these discs together on application of heat and pressure in the press. Preferably the reinforcing disc is of metal foil (e.g. of polished aluminium), or of heavy-weight or strong or stiff paper (e.g. linen paper) or of light-weight cardboard, resistant to rupture during softening and spread of the core material. Preferably the reinforcing disc occupies only a small central region of the adjacent paper disc (e.g. of three inches diameter for a twelveinch record). Preferably the core material is a vinyl (e.g. polyvinyl chloride) polymer in which are incorporated a plasticizer (e.g. 5 to 15% of dioctyl phthallate), and a lubricant, (e.g. 1 to 2% of lead or zinc stearate). Preferably the core is a biscuit cut from stock sheet, softened by preheating and folded so as to be located within the confines of the upper and lower reinforcing discs. Where, as preferred, the playing layer is initially provided in the form of a sheet, it consists of thermoplastic polyvinyl chloride incorporating 1 to 2% of lead or zinc stearate as a lubricant. The picture- (or other information-) bearing disc is preferably clay-coated paper receptive to fine screen colour printing by letterpress, lithographic or offset techniques, or to line printing, or, (where line printing only is required), strong calendered paper. The displayed matter may be a photograph or the words of a song.

Abstract: 1,239,599. Sampling amplifier. INTERNATIONAL BUSINESS MACHINES CORP. 23 Oct., 1968 [24 Oct., 1967], No. 50212/68. Heading H3T. Complementary transistors 95, 96 supplying a load ZL are connected to an input signal terminal 80 by a gating circuit such as a diode bridge, 81 to 84, only when the the gating circuit receives a bias current from source 77. Each complementary transistor 95, 96 may have an associated transistor 97, 98 to increase current gain. A negative voltage or pulse (strobe) applied to terminal 90 of the source 77 produces a current flow I, from transistor 93 and into transistor 94, which current divides between the diodes 81, 83 and the diodes 82, 84, the transistors 95, 96 both being conductive as long as the input at 80 is zero. If the input goes positive, conduction through diodes 81, 84 is cut-off, the input current flowing through diode 83 to transistor 94, and the current I 1  from transistor 93 flowing through the diode 82 and resistors 86, 115 to bias the transistor 95 into greater conduction, the transistor 96 being simultaneously turned off. A negative input at 80 correspondingly increases the conduction of transistor 96 and turns transistor 95 off. For any input signal, the output voltage V o  changes to become equal to the input, whereupon all the diodes and both the transistors 95, 96 are conducting again, their various levels of conduction being such as to maintain the balance. The transistors 93, 94 of the current source 77 each form one of a respective emitter coupled pair the transistors 91, 92 in each pair being normally conductive in the absence of an input at 90. An alternative gate (Fig. 3, not shown) uses only two diodes, one (60) connected between the signal input (V R ) and the first part (58) of the current source, and the second diode (61) being connected between the two parts (58, 59) of the current source; the function of the second diode (61) and the second part (59) of the source being connected to the complementary amplifier. The current available from part (58) in this case has to be twice that to part (59).
