Title: Improvements relating to the ventilation of dynamo-electric machines
IPC: H02K9/10
Filed: 1928-12-06
Abstract: 321,853. Kuyser, J. A., and Associated Electrical Industries, Ltd. Dec. 6, 1928. Dynamos and motors, cooling and ventilating. -In a ventilating system in which fans are provided on the rotor or elsewhere for constantly propelling air through the end parts of the machine, the air gap and ventilating ducts in the machine, two or more external fans are provided adapted to be put in action independently and so arranged that the operative ones are caused to circulate air through the ventilating ducts belonging to the inoperative fans. A cooler may be included in the system. In the form shown two external fans are employed. The conditions with these fans in operation are shown in Figs. 1 and 2 and with the fans out of action in Figs. 3 and 4. Figs. 2 and 4 are sections respectively on the lines II-II and IV-IV. The machine has permanently-running end fans 2, 3 and three stator chambers 4, 6, 8 communicating through trunks 9, 10, 11 to an exhaust chamber 12. Two additional chambers 5, 7 communicate respectively through trunks 13, 15 with the delivery sides of the external fans 14, 16 which are independently driven and draw air from an intake chamber 17. This chamber also supplies the rotor fans at 18, 19. When the hinged dampers 20, 22 in the trunks 13, 15 are set as in Figs. 1 and 2, and the fans 14, 16 are in operation, the trunks 10 and 11 are connected to the exhaust chamber 12 through the openings 23 between the dampers and the fan casings, the trunks 13, 15 being shut off from these openings. Thus, air entering the chamber 17 over the cooler 24 is passed through the machine partly by the fans 14, 16 to the chambers 5, 7 and partly by the rotor fans to give an intensive cooling. At low loads, one or both of the fans 14, 16 may be stopped and the dampers 20, 22 moved to the position shown in Fig. 4 so as to connect the trunk 13 or 15 to the exhaust passage 23 and convert it from an air-supply duct to a withdrawal duct for the fans which remain in action, e.g. the end fans 2, 3 only when both fans 14, 16 are stopped as shown in Figs. 3 and 4. The dampers may be interlocked with the fan-motor switches or the dampers may be operated by the pressure developed by the fans. Means may also be provided for automatically starting and stopping the fans in accordance with the load on the machine. The cooler may be omitted and the intake and exhaust chambers 17, 12 connected to atmosphere\ in the case of an open-circuit system of cooling.

Abstract: 1508309 Plastics film wrappers IMPERIAL CHEMICAL INDUSTRIES Ltd 22 May 1975 [15 Aug 1974] 35972/74 Heading B8C A wrapper of polyolefine film 5, 6 has directly heat-sealed thereto a polyolefine tear-tape 15, the polyolefine of the tear-tape being compatible with the polyolefine of the wrapper and having a melting point at least 12‹ C. higher than that of the polyolefine of the wrapper film. The wrapper and the tear-tape are preferably made of low and high density polyethylene and should have, at 23‹ C., densities not exceeding 0À93 and 0À95 g./c.c., respectively, the tensile strength of the tear-tape film preferably being at least 25% higher than that of the wrapper film and preferably being of the type produced by the tubular extrusion-blowing process. The wrapper film and tear-tape have thicknesses, e.g. of from 38 to 50 microns, and from 50 to 100 microns for small packages, respectively, and, for pallet loads &c., 250 microns, or even higher, and 250 to about 370 microns, respectively. The tear-tape is preferably heat-sealed to the outer surface of the wrapper the seal preferably lying along the centre, but preferably not up to the edges, of the tear-tape. As shown, articles 2 are intermittently advanced, by a conveyer 1 to successively entrain, and be enveloped by, sealed-together webs 5, 6 of heat-shrinkable polyethylene packaging film and to be forwarded to heat-sealing and cutting jaws 4 where the draped webs 5, 6 are heat-sealed together behind the respective article 2 and cut and resealed to reform a continuous web 5, 6 ready to be entrained by the succeeding article. An intermittent conveyer 3 transports the wrapped articles to a shrink tunnel 10. A tear-tape 9, provided as a separate ribbon, or preferably cut from a web of tear-tape material, is heat-sealed by appropriately located jaws 7, 8 across the underside of web 6 during each stationary period of the conveyers 1, 3. Alternatively, the intermittently driven supply reels 11, 12 for the webs 5, 6 may be continuously driven with the provision of web accumulators, not shown. The formation of the seal at a relatively high temperature provides a weakening of the web at the edge of the seal which facilitates tearing and a tear-tag may be left at one, or both, ends of the tear-tape. A tear-tape film 15, Fig. 3, of a width equal to the required length of each tear-tape, is fed by rollers 14 and guided by fingers 16 to further guides 17, 18 which present it in transverse contact with a wrapper film 19 for heatsealing thereto by heat-sealing jaws 20, 21, cutter blades 22, 23 severing off successive teartape strips of the film 15. The blades 22, 23 may be replaced by a heated knife.

Abstract: 1,273,548. Braking systems. GIRLING Ltd. 2 July, 1969 [29 July, 1968], No. 36031/68. Heading F2F. [Also in Division H3] A braking system for a vehicle comprises means for applying braking force to a wheel, speed sensitive means for sensing the speed of the wheel, and control means operable by the speed sensitive means for reducing the braking pressure applied to the wheel until the speed of the wheel falls to a predetermined value, the speed sensitive means comprising a generator 10 driven by the wheel and producing an alternating signal of frequency dependent on the speed of the wheel. The generator output is applied to a frequency sensitive circuit which produces an output the polarity of which changes at a predetermined wheel speed to operate the control means. In the construction shown a phase shifting network in the form of a series circuit including a pair of resistors R 1  and R 2  and a capacitor C 1  is connected across the generator 10. The phase shifting network forms part of a frequency sensitive circuit which includes a P-N-P transistor Q 1  and a capacitor C 2 . The arrangement is such that as the wheel speed increases from zero the capacitor C 2  acquires a negative charge which increases until a value of wheel speed is reached whence the negative charge decreases until the wheel speed approaches the predetermined value at which value the charge acquired by the capacitor C 2  becomes positive. The control means comprises a relay, conveniently a reed relay, having a coil 13, actuation of which energizing a brake control 14 in the form of a solenoid to induce braking pressure.

Title: Improvements in and relating to storage and transfer devices
Inventor: GRIBBLE MAURICE WOOLMER
IPC: H03K3/288
Filed: 1962-09-22
Abstract: 1,024,015. Matrix stores. FERRANTI Ltd. Sept. 16, 1963 [Sept. 22, 1962], No. 36136/62. Heading G4C. [Also in Divisions H1 and H3] An information storage device consists of a matrix of storage cells, each comprising a bi-stable transistor circuit, formed within a single semi-conductor slice (see Division H1). The circuit of a typical cell of such a matrix as shown in Fig. 2 consists of two cross-coupled pairs of transistors. In the storage condition of zero volts at W and + 1 volt at D1 and D2 only transistor 22 or 23 is conducting. Information is read out non-destructively as a pulse at, e.g. D1 by applying a + 3V pulse at W to cut off the conducting transistor, e.g. 22 and turn on transistor 21. The circuit reverts on termination of the pulse. New information is written in by applying a pulse at D1 or D2 while the 3V pulse is on W to switch on transistor 22 or 23. Fig. 4 schematically illustrates the matrix with a diode decoding network. Thus information is read out of marked cells 41 along line D1A or D2A by application of simultaneous pulses to lines W3 and W5 or W7 respectively, and new information put in by applying an overlapping pulse on D1A or D2A. In an alternative arrangement the diode network is rendered unnecessary by constructing the individual cells, Fig. 6, with a further pair of cross-coupled transistors with a common emitter connection. In the store condition transistors 62 and 63 or 64 and 65 are both conducting. Information is read out at D3 or D4 by simultaneous pulses at WX and WY and information put in by applying a pulse at D3 or D4 at the same time. Such cells are arranged in the matrix shown in Fig. 7 so that simultaneous pulses on lines WY8 and WX4 or WX7 give read out at line D3 or D4, the stored information being altered by applying a pulse at D3 or D4 simultaneously, with the pulses on the appropriate WX and WY lines.

Abstract: 1463859 Cameras SEIKO KOKI KK 21 Aug 1974 [24 Aug 1973] 36788/74 Heading G2A A camera has a counter 6 which prior to exposure counts a number of pulses proportional to exposure time, a display circuit 5 controlled by counter 6 to indicate a shutter speed appropriate to the count and a timing switch S3 which is actuated by the initial movement of the shutter (a) to call out the stored count for controlling shutter time and (b) to switch off the display circuit 5 and thereby save battery power. As shown S3 operates via a delay circuit 14 to synchronize call out of the count with the moment at which the shutter actually opens. In operation a brightness time converter 1 opens a gate 3 for a period dependent on subject brightness and counter 6 receives pulses passed by gate 3 from a generator 2. The outputs f3, f4 ... fn and f3, f4... fn of the stages of counter 6 control AND gates 21 to 29 for illuminating a lamp or light emitting diode L1, L2 ... Ln appropriate to the count. When S3 is opened AND gates 25-29 are all closed to extinguish L 1-Ln, and also a dividing circuit 4 is actuated to pass pulses from generator 2 to counter 6 to reverse the count. When the count is zero, a detector 7 causes the shutter to be closed. Instead of a reversible counter, the circuit may have a first counter to count the brightness pulses, and a second counter to count standard pulses when the shutter opens, the shutter being closed when the counts are the same.
