Filed: 1971-09-09
Abstract: 1409238 Drum brakes GIRLING Ltd 8 Sept 1972 [9 Sept 1971] 42018/71 Heading F2E First and second friction means are applied to at least one cylindrical surface of a rotor, the first friction means being carried by a rigid carrier adjacent the rotor and capable of movement transverse to the rotor axis but restrained against rotation around the axis, the second friction means being located on the opposite side of a diametral rotor plane normal to the rotor axis and restrained against rotation thereabout, actuation of the means being by an actuator between the carrier and the second friction means, the actuator having a housing secured directly in or to a fixed support. The carrier comprises two spaced parallel plates 3, 3<SP>1</SP> surrounding a drum 1 and carrying two shoes 7, 8 constituting the first means, pivotable in holes in the carrier. A third shoe 6 is applied by a rotating lever 10 acting through a sleeve 11 in the housing 12 and a shaft splined to the sleeve and threaded to co-operate with a sleeve 14 held in the carrier. Alternatively the lever 33 is splined directly on to the shaft and can be removed and adjusted for shoe wear. The shoes alternatively engage different diameter external drum surfaces or they engage internal surfaces. The first friction means may be a lining or linings. To provide a self-servo action of the shoe 6, the shoe is allowed peripheral movement in the carrier and rocks about one apex of a triangular plate which can rock about either of two bolts 4 adjacent the other apices. To aid assembly of the splined sleeve 11-shaft arrangement, a plate, seen next to the sleeve 14, engages at least one spline of the shaft to prevent its rotation or loss, by means of teeth, a coiled spring or a spring tooth. Upon introduction of the sleeve 11, the plate is pushed into its illustrated position.

Title: Apparatus for correction of electrical signals having drifting base lines
IPC: G01N30/86
Filed: 1971-09-10
Abstract: 1345720 Pulse circuits INSTRUMENTATION SPECIALTIES CO 10 Sept 1971 [17 Nov 1970] 42340/71 Heading H3T [Also in Divisions G1 and G4] Base line correction of a waveform, e.g. from a gas or liquid chromatography apparatus 10, is effected by repeatedly sampling and storing 20 the value of the waveform when no peak is present, i.e. the base line value, and arranging that when a peak is detected the waveform is diminished by the value of the last stored base line value so as to produce a corrected waveform. The corrected waveform is applied to a voltage controlled oscillator 52 whose cycles are counted 56 to provide both a measure of the area under the peaks and a print out 60 in the usual way. A circuit 12 comprising a slope detector 14, as described in Specification 1,341,065, and a slope logic 16, as described in Specification 1,343,362, produces a series of negative pulses (5v to 0v) on a lead 18 when no peak is present. These pulses cause a transistor 22 to conduct and repeatedly close a contact 34, in a circuit which functions both to sample and hold the input signal received via a low pass filter 38 from the chromatograph apparatus 10, and also to produce an output on a lead 48 which, whenever contact 34 is open, is the difference between the input signal and the last sampled value. The circuit comprises an inverting amplifier 36, with equal input 40 and feedback 44 resistors, the input resistance being in series with a capacitor 42 and the feedback resistor being shunted by a capacitor 50, for noise reduction. When the contact 34 is closed, since resistors 40 and 44 are equal, the capacitor 42 is charged to half the input voltage. When the contact 34 is open, the potential across capacitor 42 is effectively subtracted from the input signal and added to the output signal, thereby providing the desired corrected signal on lead 48. The system described also includes a printer logic 68 which causes a print command circuit 58 to store, from a clock 64, the time of occurrence of the summit of a peak, this being signalled by a pulse on a lead 70. This time is stored until either a pulse on the line 18 occurs indicating the return to base line, or a signal on a lead 72 occurs indicating that the next peak has commenced, whereupon the count then reached in accumulator 56 (which represents the area under the peak) and the summit time are both printed or otherwise recorded, e.g. on punched paper tape.

Filed: 1961-11-30
Abstract: 949,257. Control of D.C. motors; converting. R. ROUXEL, and K. SCHNEIDER. Nov. 30, 1961 [Dec. 7, 1960], No. 42808/61. Headings H2F and H2J. [Also in Division G3] A diesel-electric traction installation comprises a diesel engine driving an alternator which supplies a squirrel cage motor over a static converter including rectifiers controlled by a device so as to feed a variable frequency voltage to the motor, the arrangement being such that the load on the diesel engine is maintained constant so that the engine can run at its optimum speed as regards wear and consumption. As shown, an alternator A driven by a diesel engine D supplies an asynchronous motor M over a converter C comprising controlled rectifiers such as thyratrons, ignitrons or semi-conductor rectifiers. A tacho-generator T supplies a voltage V proportional to the speed of the diesel engine to a comparator DI which also receives a reference voltage R, representative of the desired optimum engine speed, from the slider of a potentiometer P. If the voltages V and R differ, the comparator DI delivers an error signal to a control device DC which determines the frequency of ignition pulses to the converter C, whereby the frequency of the supply voltage to the motor M is adjusted so as to reduce the error signal to zero. If, for example, the speed of the diesel engine decreases because of an increase in load, the error signal applied to device DC results in a lowering of the frequency of the supply to the motor M which then runs at a lower speed, with a higher torque, whereby the overload on the diesel engine decreases until the engine speed returns to its reference value.

Title: Method of transmitting intelligence by means of a time division (time multiplex) system and arrangement for carrying out the method
IPC: H04Q11/04
Filed: 1963-10-31
Abstract: 1,069,094. Automatic exchange systems. TAVKOZLESI KUTATO INTEZET. Oct. 31, 1963 [Oct. 31, 1962], No. 43083/63. Heading H4K. In a T.D.M. system each intelligence signal is preceded by a further signal for routing it in the wanted direction. As shown incoming signals on a line such as k are sampled by a corresponding switch 12 to provide signals which are converted to P.C.M. signals r, k at 12. A generator 15k set up at the start of the call emits the coded identity Pf of the wanted line and this is gated out synchronously by a corresponding switch 14. The two are combined at 13 together with a further pulse or pulse group b for heralding the arrival of a destination code. At the outgoing side of the exchange, or another exchange connected to the preceding exchange by the multiplex highway 16, the destination and intelligence signals are separated at 18, the latter signals being demodulated at 19. The destination signals are passed directly and in inverted form to control the appropriate one of the switches 20 1  ... 20 n , whereby the decoded intelligence sample is routed to the appropriate one of the outlets 1 ... f ... n. If the incoming and outgoing lines belong to the same exchange a separate channel 25 may be provided, in which the intelligence signals, uncoded and amplitude modulated, may pass from the incoming to outgoing section of the exchange. The destination signals may also be in the form of amplitude modulated pulses. The destination code transmitters may consist of a tapped delay line the tappings feeding a common output via gates controlled in accordance with the code, Fig. 2 (not shown). Similar devices using waveguides, Figs. 3 and 4 (not shown) may be used. Each of the sets of switches 21 comprises a decoder for each switch which may consist of two delay lines, fed respectively with the code and its inverse, Fig. 5 (not shown). Tappings from the delay lines are taken at points corresponding to the code required for operating the switch and its inverse respectively and the signals so obtained combined, and fed to a threshold device which only passes a signal when all the tappings are contributing, thereby operating the corresponding switch when it receives the correct code. Busy testing, Fig. 7.-Use is made of the existence of the destination codes on the highway 16 to determine if a wanted subscriber is busy. The destination code of the subscriber is set up on switches 78, and the inverse on further switches 79 to open gates 72, 73 according to the code; and further gates 74, 75 according to the inverse. The received codes and their inverses are fed respectively to upper and lower delay lines whose tappings are connected to the respective gates. The gates feed a common output 77. If the appropriate 5-element code arrives, five gates all pass pulses simultaneously, which operates a threshold detector to give a busy indication.

Title: Process for dyeing or printing fibrous materials of cellulose
IPC: D06P1/30
Filed: 1961-12-01
Abstract: Textile materials of cellulose are dyed or printed using vat dyestuffs which contain at least one thiosulphuric semi-ester group -S-SO3-X where X is a cation and, before or during the dyeing or printing process the dyestuff is reduced to its leuco form and re-oxidized on the fibre.  Conditions may be chosen such that the thiosulphuric semi-ester residue is split off during the process. The -S-SO3-X group may be attached directly to the aromatic nucleus of the vat dyestuff or to an aromatic nucleus bound to the vattable system through an -O-, -CO-, -NH-, -S-, -SO2-NH- or -CO-NH- bridge or especially it may be bound to an aliphatic chain attached to the dyestuff molecule through an -O-, -S-, amino, -CO-NH, -SO2- or particularly -SO2-NH- bridge or a heterocyclic, e.g. triazinylamino or pyrimidinylamino, bridge.  The aliphatic chain may be interrupted with hetero atoms, e.g. O, S or N atoms.  The dyestuffs may contain other substituents usual for vat dyes such as halogen atoms, alkyl, alkoxy or acylamino groups and in certain cases sulphonic acid, sulphato or reactive groups.  Specified reducing agents are sodium hydrosulphite, thiourea dioxide and alkane sulphinic acids.  Dyeing may be effected in a bath containing the dyestuff, alkali and reducing agent at 20 DEG -90 DEG C. or by padding in the cold with dyestuff solution, squeezing, drying and then impregnating with an alkaline solution of reducing agent. Printing may be effected with a thickened paste containing usual additives.  Re-oxidation and finishing are carried out normally. Examples of dyeing and printing cotton and regenerated cellulose in a variety of ways are given as well as the preparation of the dyestuffs used by reacting the appropriate sulphochloride with b -amino-ethyl-thiosulphuric acid representative of which are <FORM:0929745/IV(a)/1> <FORM:0929745/IV(a)/2> <FORM:0929745/IV(a)/3>
