Title: Production of fabrics
IPC: D03D15/567
Filed: 1974-04-10
Abstract: 1506389 Finishing fabrics; knitted fabrics; testing fabrics IMPERIAL CHEMICAL INDUSTRIES Ltd 3 April 1975 [10 April 1974] 15875/74 Headings D1K and D1S A fabric suitable for moulding and which has an area stretch of at least 450%, preferably 500 - 900%, is produced by weft knitting, on a machine capable of making single jersey constructions, a single jersey precurser fabric under conditions giving essentially maximum loop length to the fabric stitches and minimum yarn tension, from shrinkable, unstabilised or partly stabilised bulked or potentially bulkable continuous homofilament yarn of polyester and/ or nylon such that the precursor fabric has an area stretch of at least 100%, preferably 100 - 200%, a weight in the range of 20 to 80 grams per square metre and percentage light transmission in the range of 50 to 90, these weight and light transmission properties lying within the area ABCD of Fig. 1, and subjecting the precursor fabric to a tumble bulking treatment of elevated temperature whereby it relaxes to its fullest potential. Preferably, the fabric is fed into a cool tumble dryer, the temperature is raised to the required level and the fabric is allowed to cool before being removed. The fabric is fed into the tumble dryer in such a manner that the length direction of the fabric coincides with the motion of the machine. Suitable yarns have a decitex of 30 - 200, preferably 50 - 170, are those of which the bulk has not been fully developed, e.g. yarns made by false-twisting and knit-de-knit processes. The weft-knitted fabric may be made on a flat bed or circular machine with a low knitting tension and a large stitch length. Preferably, combinations of Z- and S-twist yarns are used. Optionally, the fabric is stentered and, if tubular, slit and an adhesive selvedge applied. Before moulding, the fabric may be coated with polyvinyl chloride to produce an upholstery fabric. Resinous and plastisol finishes e.g. polyethylene or acrylic resins, may be applied to the side of the fabric to be placed against the mould surface to aid shape retention of the moulded fabric. Apparatus for measuring the light transmission of the fabric, before tumbling, Fig. 2, comprises a rectangular box divided into three compartments 3a, 3b, 3c of which the compartment 3b contains a light sensitive cell 4 shielded by a tube 9 and the compartment 3c a "bridge" circuit A powered by a source 1 which also energises a projector bulb 2. The filament of the bulb 2 is on the common horizontal axis of .the centres of apertures 6, 7. In use, a fabric sample to be tested is mounted on a pin frame which is then mounted in a slot 8 between the compartments 3a, 3b. The light is switched on and the reading on a microammeter 5 noted. Te sample is removed and the meter reading is taken with the bulb light and no fabric to give a reading corresponding to 100% light transmission. Meter readings are taken using neutral density filters of known light transmission. A calibration graph is plotted from which the light transmission of the fabric can be deduced.

Abstract: 272,932. Telefunken Ges. f³r Drahtlose Telegraphie. June 15, 1926, [Convention date]. Driving - arrangements; motor-generators. - A motorgenerator set for supplying power to radio valve transmitters or transformers consists of a motor connected to the mains and coupled to the generator in such a manner that fluctuations in the motor speed are accompanied by considerably smaller fluctuations in the generator voltage. The coupling shown in Fig. 1 comprises a disc G on the generator shaft with springs F which make frictional contact with a disc M on the motor shaft and carry centrifugal weights F. The adjustment of the springs is such that with normal motor speed there is some slip between the springs and disc M. Fig. 2 shows an embodiment in which the motor shaft carries a disc M engaged by spring-pressed weights P carried by a drum G attached to the generator. The springs and weights may be attached to the motor instead of the driven machine. The motor, generator and coupling are preferably made as one unit with a plug for connection to the lighting mains and a resistance is preferably used to enable the proper potential to be applied to the valve from the generator. The Specification, as open to inspection under Sect. 91 (3) (a), states also that when a series motor is employed " where with a diminution in the load a decrease in the number of revolutions takes place " the springs are carried by the motor, whereby constant speed of the generator is obtained. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in and relating to means for regulating dynamo electric machines
IPC: H02K17/38
Filed: 1925-06-22
Abstract: 235,917. British Thomson-Houston Co., Ltd., (Assignees of Compagnie Franþaise pour l'Exploitation des ProcÚdÚs Thomson- Houston). June 20, 1924, [Convention date]. Alternating-current commutator and induction machines; dampers on cores.- The invention relates to the system of speed regulation of an induction motor in which the secondary member is connected to the commutator brushes of a frequency changer mechanically coupled with the motor. The frequency converter is of the type shown in Fig. 2 having commutation slots E in the stator opposite the rotor commutating zones; these slots may be. provided with damping windings, preferably having no iron core. According to the invention and as shown in Fig. 3, the induction motor and the frequency changer are combined in one machine which is provided with a rotor winding fed through slip-rings, and with slots in the stator laminations opposite the rotor commutation zones. Each phase s<1> - - s<3> of the stator winding is connected to a commutator brush e<1> - - e<3> and is supplied from the secondary winding of a variable-ratio, auto- or other transformer T, the primary winding of which is connected to the commutator brushes. Speed regulation is effected by varying the ratio of the primary and secondary turns of the transformer but in order to prevent heavy circulating currents at speeds near synchronism, the cross-section of the copper in the secondary winding of the transformer is progressively decreased, as shown. Alternatively, additional exterior resistances may be inserted. The power factor of the motor may be regulated by altering the phase relation between the primary and secondary currents of the transformer. The rotor may be provided with separate commutator and slip-ring windings. The Specification as open to inspection under Sect. 91 (3) (a) comprises also the following. Two machines of the type shown in Fig. 2 are mounted on the same shaft and their rotors are fed in parallel from the same slip-rings; by relatively displacing the stators, a regulatable voltage may be taken between the two sets of brushes which are connected to a double set of slip-rings on the main motor. The transformer T in Fig. 3 may be dispensed with, in which case the machine acts as a compensated motor. Fig. 5 (Cancelled) shows a group comprising a frequency changer F of the type shown in Fig. 2, driven by a synchronous motor C, and a synchronous generator B driven by the main motor; the positions of the machines F and B are interchangeable. The frequency converter may be employed as an exciter for a motor of the Scherbius type. Inductances may be placed in series with the slip-rings b of the frequency converter. This subjectmatter does not appear in the Specification as accepted.

Title: Improvements in and relating to the manufacture of decorative electric incandescent lamps
IPC: H01K7/06
Filed: 1952-06-30
Abstract: 709,865. Electric incandescent lamps. BRITISH THOMSON-HOUSTON CO., Ltd. June 30, 1952 [June 30, 1951], No. 16400/52. Class 39 (2) In making electric incandescent lamps of the kind having envelopes of irregular shape, e.g. in the shape of fruit, lanterns &c. bulbs which are of globular, tubular or pear shape have a lamp mount sealed within them in a lamp-making machine of the conventional type and are then heated to a pliable condition while a non-oxidizing gas is introduced at a pressure sufficient to prevent them from collapsing, after which substantially the entire body portions of the envelopes are reshaped prior to their being evacuated and tipped off or sealed. Reshaping is effected by positioning a two-part mould about a bulb and admitting a puff of non-oxidizing gas into the exhausting tube. Fig. 8 shows a bulb 28 that has been inverted after sealing a glass stem-type mount 22 and exhausting-tube 24 within it, the latter tube being held in a rubber chuck 12 of a conventional machine whereby a non-oxidizing gas at low-pressure is introduced while the exterior of the bulb is flooded with relatively soft gas flames 13. When softened the bulb is immediately enclosed in a two-part mould 15, Fig. 9, having a mould cavity 16 of the desired configuration, and a puff of non-oxidizing gas causes the glass to take the shape of the cavity. After hardening, the reshaped bulb is exhausted, sealed, and capped. A bulb of the butt-sealed type may be reshaped in a similar manner.

Patent GB-866257-A (GB)
Title: Arrangement for measuring nonlinear distortions in frequencymodulated systems
IPC: G01R27/32
Filed: 1957-05-24
Abstract: 866,257. Electric tests. STANDARD TELEPHONES & CABLES Ltd. May 24, 1957 [May 30, 1956], No. 16532/57. Class 37. An arrangement for measuring non-linear distortion in a multi-channel transmission system employing frequency modulation comprises means for supplying to the input of the system a sweep frequency below the lowest frequency in the signal band and having an amplitude sufficient to cover the whole frequency modulation range, and a test frequency, lying within or above the signal band and having a smaller amplitude than that of the sweep frequency; means for selecting from the system output a component wave of the test frequency which is amplitude modulated by static non-linear distortion components and is phase modulated by dynamic non-linear distortion components; and means for separately recovering and displaying on a cathoderay tube the respective envelopes of the amplitude and phase modulations of the component wave. Oscillators 2, 3 respectively modulate the carrier of a frequency modulated transmission system, or test network 1, with a test wave U # cos # s t and a sweep wave U n cos # n t; and the test frequency component of the system output is filtered at 6 and fed to peak rectifier 7 which recovers the amplitude modulation envelope of the test frequency and applies it to the Y-plates of cathode-ray tube 9, the X-plates of which are connected to the sweep oscillator 3. From the resulting trace, the static distortion produced by the system may be determined by a computation disclosed in the Specification. The dynamic distortion of the system is determined by additionally feeding peak rectifier 7 with the output of the test oscillator 2 phase-shifted through #/4, the amplitude thereof being adjusted by attenuator 11 so that the reading of voltmeter 10 is unchanged. A further computation disclosed in the Specification enables the dynamic distortion to be determined from the new trace.

Title: Data processing systems
IPC: G06F12/00
Filed: 1973-04-06
Abstract: 1432223 Interface apparatus SPERRY RAND CORP 6 April 1973 [7 April 1972] 16584/73 Heading G4A Memory request interface apparatus includes a pair of address registers 206, 207 (Fig. 3), which are used alternately to address a main memory and so increase the working speed of a data processing system. As described (Fig. 1, not shown) main and extended storage (102, 103) may be accessed using interface circuitry under the control of instruction and operand control (106, 109) in a command arithmetic unit and under the control of data control (116) in an input/output arithmetic unit. The interface circuitry controlled by the operand control is shown in detail in Figs. 3, 3A, 3B. Normal operation.-In operation initially a clear pulse on line 223 resets request address flip-flops 255, 256 and sets acknowledge enable flip-flop 231. A subsequent start pulse on line 224 sets flip-flop 255 and 283 and resets flipflop 284. The setting of flip-flop 255 results in a request to operand control for an address, the control responding by sending a "stage matrix one" signal on lead 221 and feeding a 74 bit word comprising 24 address bits and two parity bits and 36 data bits and two parity bits on leads 220 to address register 206. The register 206 is connected via AND gate 208 enabled by the output of flip-flop 283 to memory drivers 211 to address the main memory, the 76 bit word also being fed via address decoder 218 to memory request gates 219. The staging signal after a delay determined by delay line 233 resets flipflop 255, sets memory request flip-flop 230 to enable the gates 219 and generates an acknowledge signal back to the operand control. The next word from operand control is then sent together with a "stage matrix two" signal so that it is fed to register 207. When the main memory sends an acknowledge pulse on line 258 flip flop 283 is reset and flip flop 284 set so that gate 213 is enabled to feed the contents of the second register to the memory drivers. Operation in extended cycle mode.-When a word transmitted by operand control necessitates an extended cycle time a decoder 320 receiving the word triggers either flip flop 321 or 322 (in dependence on which register 206, 207 is being used) which results in a common extended cycle flip flop 326 being set. This results in gates 285, 286 being inhibited to prevent switching of enable flip flops 283, 284 when the next acknowledgement pulse arrives from the memory. After a delay determined by delay line 328, the flip flops 321, 322 and 326 are reset so that AND gates 285, 286 are primed and the output of the delay line 328 is fed via OR 287, 288 and one of the gates 285, 286 to switch the states of the bi-stables 283, 284.
