Title: Improvements in or relating to toe puffs for boots or shoes
IPC: A43B23/08
Filed: 1931-11-21
Abstract: 392,956. Boots and shoes. BRITISH UNITED SHOE MACHINERY CO., Ltd., BANCROFT, W. H., and HILL, M. G., Union Works, Belgrave Road, Leicester. Nov. 21, 1931, Nos. 32300/31 and 16134/32. [Classes 17 (i) and 17 (ii).] Stiffeners.-Relates to toe puffs of the kind provided with a flimsy edge portion by expelling the stiffening impregnant from said portion'by pressure, and consists in forming the puff with an impregnated body portion 10 of uniform thickness, a tapering portion 14-16 containing a smoothly graduated quantity of impregnant, a thin portion 16-18 of uniform thickness from which the impregnant has been substantially wholly expelled, and an edge portion 19 tapering to knife-edge thickness and likewise free from impregnant. When apparatus such as is described in Specification 236,600, [Class 17 (ii), Boots and shoes, Construction of], is used for pressing the puffs, the die matrix 35 in the die roll is made of a depth and width to accommodate substantially the whole of the puff 10, Fig. 4, and the rolls are set with their surfaces in contact. A cylindrical portion 36 of the matrix, which acts to compact the portion 16-18 of the puff, merges into the cylindrical surface of the roll through a bevel face 38, which acts to produce the taper edge 19 of the puff. Where cylindrical rolls have been used for pressing puffs having curved rear edges, unequal pressure at such edges has resulted from the spring of the roll-carrying parts of the machine. This is overcome by tapering the die roll slightly from its centre to its ends, Fig. 5, or from its ends to its centre in the case of puffs having a convex rear margin. The die cavity 40 is formed of normal depth at its various parts. Such a tapered roll is set with its portion of maximum diameter in contact with the surface of the co-operating roll. The tapering of the roll may obviate, to some extent, the modified matrix configuration shown in Fig. 4. British Specifications 345,797, 348,533, 351,037, 360,829, and 380,043, and U.S.A. Specification 1,704,276 also are referred to.

Abstract: 1352359 Power steering MITSUBISHI JIDOSHA KOGYO KK 9 July 1971 [10 July 1970] 32448/71 Heading B7H [Also in Divisions G3 and F2] An hydraulic power steering system for a vehicle, having improved response following movement of the steering wheel, comprises a conventional steering - wheel - operated valve which produces an output proportional to the angular position of the steering wheel and a pump driven by the steering wheel which produces a constant output per revolution of the steering wheel and which supplies a further valve which produces an output proportional to the angular velocity of the steering wheel, the two outputs being fed to an actuator for the steered wheels. In one embodiment (Fig. 8) steering wheel 914 operates via steering box 912 an arm 918 which moves a spool valve in housing 922 to control fluid flow from engine-driven pump 934 to power-steering ram 932 which acts on a rod 920, which is rigid with housing 922, to steer the wheels 924. A pump 114 producing a constant output per revolution is driven by the steering wheel 914 and supplies fluid to the opposite end chambers 57b and 58b of further spool valve 22b (Fig. 9). Spool 51b of the valve is centred by springs 54b and has an orifice 70b in a central passage. Thus spool 51b is moved according to the angular velocity of the steering wheel 914 and allows fluid from further engine driven pump 34b, which enters the valve at 62b, to be fed to the actuator 932, via ports 60b and 61b, in addition to the fluid from valve 922. In a further embodiment (Fig. 10) a conventional control valve 912b of the rotary type is provided having torsion-bar lost motion and recirculating-ball steering gear power assisted by fluid from engine-driven pump 934. Pump 114, similar to that in the first embodiment, supplies fluid to a rotary control valve 122b which produces an output proportional to the angular velocity of the steering wheel 914 which is also fed to the main control valve 912b, the two outputs operating the steered wheels 924 via pitman arm 918 and rod 920.

Filed: 1975-08-04
Abstract: 1497102 Amplifiers RCA CORPORATION 4 Aug 1975 [16 Aug 1974] 32492/75 Heading H3T A current amplifier, Fig. 1, comprises two junction transistors 101, 102 with their emitters commoned and collectors connected to input and output terminals 104, 106 and a field effect transistor 103 with its gate connected to the input terminal and its source connected to the bases of the junction transistors. The drain of transistor 103 is connected to a potential source to provide the base current for transistors 101, 102. Emitter resistors 201, 202 and a bias resistor 203 may be provided, Fig. 3. One or more diodes may be connected in series with resistor 203. MOSFETs 301, 302 may be connected in cascade with transistors 101 and 102 to reduce the output impedance and arranged to keep equal potentials on the collectors of transistors 101 and 102 (preferably equal to the base potentials thereof). Transistors 301, 302 may be replaced by bipolar transistors (401, 402), Fig. 4 (not shown), but since the bases draw current they must be connected to a supply separate from the input terminal. If this source is poorly regulated (e.g. a resistive divider across the source 109) an avalanche diode is connected between the source of transistor 103 and the bases of transistors 101, 102 to give an offset potential permitting more variable bias on the transistors (401, 402). The offset may alternatively be provided by a self-biased MOSFET. The transistors (401, 402) may be biased by the source of transistor 103 with a suitable diode or resistor between the bases of transistors 101 and 401. All the circuits may be constructed using NPN transistors for the PNP and n-channel instead of P- channel FETs. Those circuits using very small collector/base potentials may then comprise transistors with very thin bases and hence high h fe  In another embodiment, Fig. 8, the necessary potential offset between the source of transistors 103 and the bases of transistors 101 and 102 is provided by transistors 801, 802 which also connect the base currents of transistors 101, 102 to the input and output respectively to compensate for any inequality of the transconductances of transistors 101 and 102.

Abstract: 1300481 Digital transmission systems INTERNATIONAL BUSINESS MACHINES CORP 7 July 1970 [30 July 1969] 32802/70 Heading H4P Each of a plurality of terminals connected to a common channel and forming part of a transmission system comprises a master control having means for checking the parity of control signals from satellite devices whereby a malfunction can be detected. Each accessed satellite forms signals on an odd number of control lines and the master control checks such odd parity. A second means checks the parity of control signals to satellites to detect malfunction of the master control. A principle feature of the invention is to provide a self-diagnostic system providing a real time error detection location and indication so that faults are localized to a functionally replaceable unit. Each master unit monitors its satellite controls only one of which may be operative at any one instant. Satellite controls may also be internally self checking i.e. a serializer-deserializer "Serdes" 22 may correctly receive information but may fail to forward it correctly, and if an error in shifting is made, the master control is notified. When receiving, the Serdes is assigned a parity bit and parity is predicted as each bit is shifted and hence by comparison is checked. Any terminal on the system may act as a master station and may comprise a master control 27, checking equipment 23, keyboard 20, printer 21, and transmit-receive equipment including Serdes units 22 connected to a transmission medium 13 which may be line or radio. The master control 27 includes a diagnostic register 40 supplying data signals to a coder 41 into a vertical redundancy check 42 and register 43. Register 40 supplies control signals along a cable 44 to vertical redundancy check 45 and register 46. Signals from registers 43, 46 are checked in VRC's 48, 49. Clock 50 supplies timing signals. Control 23 co-ordinates operation of equipment within the station as well as between stations.
