IPC: B29C44/12
Filed: 1966-11-09
Abstract: 1,103,236. Boots &c. TOYO RUBBER INDUSTRY CO. Ltd. 9 Nov., 1966, No. 50238/66. Heading A3B. [Also in Division B5] A shoe having a moulded-on sole of polyurethane foam is made by casting or pouring a liquid polyurethane-forming mixture into a mould which is closed by a lasted shoe upper and which is maintained at a predetermined initial temperature, and allowing the liquid polyurethane-forming mixture to foam so that the sole becomes bonded to the shoe upper. The mould consists of a base 10 and split side walls 2 clamped together by bolts 4, 5 and the lasted upper is held in position by a clamp 16 on a frame 18 which is fixed to the mould base by pins 19. The polyurethane-forming mixture may be poured into a preheated mould before it is closed by the lasted upper or may be injected into a preheated mould after the mould has been closed by the lasted upper. The mould may be preheated and maintained at a temperature between 20‹ and 80‹C. depending on the type of foam required, the lower temperatures producing a more rigid foam sole. The sole may be removed from the mould after complete curing of the sole or may be removed after primary curing of the sole, the last being removed from the shoe after secondary curing. Shaped bodies of rubber, synthetic resin or metal may be placed in the mould to produce skidresistant or abrasion resistant soles. The mould may be coated with a release agent or lubricant or may be formed from a material which is easily separable from the polyurethane foam, e.g. polyethylene, polypropylene or polystyrene. Alternatively a mould release film 17 (Fig. 5) of the above synthetic resins may be provided in the mould. The mould release film 17 may be held in position by clamps 14 and may be vacuum formed to the shape of the mould, the mould being evacuated along ducts 6, 7, 8. The examples describe particular polyurethane forming mixtures.

Title: Control system for a magnetic tape unit
IPC: G11B20/10
Filed: 1970-10-28
Abstract: 1332193 Magnetic tape control system FUJITSU Ltd 28 Oct 1970 [28 Oct 1969 26 Nov 1969] 51315/70 Heading G4C A magnetic tape control system comprises a decoder 1 responsive to programme instructions indicating read/write operations and one of two data packing densities to be used to generate signals on a selection of its outputs, first, 1-2, 1-3, and second 1-4, 1-5, memories respectively storing signals from the decoder indicating tape packing density and read/write commands, a first device 5 for generating a continuous output dependent on the required packing density, a second device 10 for overriding the first device when a read instruction is decoded to make the first device produce an output indicative of particular packing density, a device 16 responsive to a packing density identification burst on the tape, and a device 17 which, if necessary, resets the overriden first device which then produces an output corresponding to the packing density indicated by the device 16. As described a magnetic tape data store is capable of storing data at two packing densities viz. 800 or 1600 bits/inch, a series of binary 1's (indentification burst) being recorded at the start of a tape to indicate the larger density. The invention is designed to prevent misreading of the indentification burst. A command designating the packing density is decoded and used to set or reset flip-flop 5. A read/write instruction is then decoded and used to set the corresponding flip-flop 1-4 or 1-5. If the instruction is a read instruction flip-flop 5 is set to indicate 1600 bits/inch. If the identification burst is not detected the NOT circuit 17 changes the state of flip-flop 5 to indicate 800 bits/sec., conversely if the identification burst is detected the state of flip-flop 5 remains unchanged. The specification also describes a circuit for detecting the identification burst which comprises alternate integrating and threshold circuits connected in cascade. The time constants of appropriate ones of the integrating circuits are chosen such that the circuit produces a signal indicating the presence of an identification burst only if 200 consecutive 1 bits are detected. Thus data and noise signals cannot be confused with an identification burst. In a modification a counter may be used to count the binary 1's of the identification burst. An aluminium strip and a photo-cell are used to detect the beginning and end of a tape.

Filed: 1974-11-27
Abstract: 1443637 Rockets R ALKAN & CIE 27 Nov 1974 [13 Dec 1973] 51486/74 Heading F3C [Also in Divisions G4 and H3] A device for transmitting and receiving signals on a single transmission line comprises a transmission unit I incorporating a set of Zener diodes VR1, VR2, VR3 arranged to provide different reference voltages and a selector switch S1 arranged to connect the reference voltages selectively to the line, and a receiver unit 11 comprising transistors Q1, Q2, Q3 arranged to be switched by voltages supplied from the line through a second set of Zener diodes VR4, VR5, VR6, the reference voltages of the diodes of the second set lying between those of the first set so that different transistors are switched when the selector switch S1 is adjusted. In Fig. 1, the first so many of the outputs A, B, C are grounded, depending on the setting of S1, but this can be decoded to a 1-outof-4 selection, e.g. for control of aircraft rocket or cartridge firing-rate. In a second embodiment (Fig. 2, not shown), the transistors connect respective resistors to control the frequency of an oscillator controlling the firing rate, and if the selector switch is in the neutral "O" position, a potentiometer in the receiver unit is connected in instead. In a third embodiment (Fig. 3, not shown) to control volley-firing magnitude, logic decodes the transistor outputs to 1-out-of-3 form, there being a position of the selector switch connected directly to the 24V supply without a Zener diode, this position causing the control outputs from the receiver unit to be controlled from a selector switch in the receiver unit instead of from the transistors.

Title: Circuit arrangemnet for control of the energy of a thyristo rized horizontal deflection circuit
IPC: H04N3/22
Filed: 1973-11-09
Abstract: 1408720 DC-DC converters LOEWE OPTA GmbH 9 Nov 1973 [11 Nov 1972] 52222/73 Heading H2F [Also in Division H3] To maintain constant the ratio of e.h.t. voltage to the output deflection current of a thyristor line deflection circuit (upper half of Fig. 3), regardless of variations in power supply or beam current, for example, a feedback circuit (lower half of Fig. 3) responsive to the deflection voltage controls the firing time of a thyristor 20 supplying power to the deflection circuit. This governs the level of power stored in inductor 12, and this in turn governs the deflecton voltage produced in known fashion by flyback thyristor 1, LC circuit 5, 6, sweep thyristor 3, and diodes 2, 4. The deflection transformer 8 has a secondary tapping driving rectifier 29 and capacitor 30, whose stored voltage then varies with variations in supply to, or load on, the transformer. When the voltage is large enough to make a Zener diode 32 conduct, T33 and T36 cause a voltage to build up on C43 representing the deflection voltage amplitude. A sawtooth generated on C45 by pulses at A from a line oscillator (not shown), is compared with the C43 voltage, and T44 conducts earlier or later in dependence on the comparison. T44 output produces pulses from shaper circuit T48, T57, T60 to fire thyristor 20.

Abstract: 1531490 Control of DC motors CABLEFORM Ltd 14 Dec 1976 [24 Dec 1975] 52782/75 Heading H2J A D.C. series motor 4, 5 is controlled by a system having a section I operating in a manner described in Specification 1,328,800, a section II operating to vary the mark/space ratio of the pulses in section I in accordance with a demand signal from section III, and a section IV responsive to the signal from a motor-current sensing resistor 8 to reduce the maximum mark/space ratio of the pulses that may be applied to the motor when the current is below a predetermined limit, thereby preventing the motor overspeeding on light loads without the need to add a shunt winding to overcome this problem. The current signal determines the conductivity of transistors 11, 12, 13, 14 and hence the voltage across the track of a potentiometer 9, 10 supplying the demand signal. The maximum mark-space ratio may be proportional to the motor current when it is below the limit I 0  determined by the setting of a resistor 25, typical characteristics of mark/space ratio and motor speed against current being discussed for various settings of the wiper 9, Figs. 3 and 4 (not shown). To obtain modified characteristics for wiper settings below the maximum, Figs. 6 and 7 (not shown), the series combination of transistor 14 and a resistor (31) is connected in parallel with the potentiometer 10, the wiper 9 and resistor (31) being connected through diodes (32) to section II, Fig. 5 (not shown), which diodes select the least positive signal for application to section II. The latter also limits the maximum motor current as described in Specification 1,330,131.

Abstract: 1,123,278. Pressure gauges. FARR CO. Dec.7, 1966 [Dec. 8, 1965], No.54865/66. Heading G1L. A pressure indicator for lubrication systems comprises an elongated body 5 having a recess 6 in one end, a socket 11 of reduced diameter, a bore 17 of polygonal cross-section, an enlarged bore 18 continuing from said polygonal bore, and a laterally dispored slot 26 intersecting said enlarged bore. A sleeve 8 is retained in the recess 6 by a fitting 7 with an orifice element 9 positioned between them. A rolling diaphram 13 is clamped between the sleeve 8 and the inner end 12 of the recess and a plunger 14 is carried by the diaphram. The diaphram, plunger sleeve and orifice element form a pressure chamber in communication with the flow line of the fluid under test. A stem 19 extends from the plunger held against rotation by the polygonal bore. The plunger is urged against the pressure in the pressure chamber by a spring 16. When the pressure in the flow line reaches a predetermined limit, the plunger is moved upwardly by the diaphram so that an indicator head 22 on the end of the stem 19 protrudes from the body 5 by an amount such that a lever 27 disposed in the slot 26 is urged beneath the indicator head to prevent the indicator head from returning into the body 5 when the pressure lowers. The protrusion of the indicator head therefore gives an indication that the pressure has reached a predetermined amerunt.
