Abstract: 804,943. Jigs for bolted or riveted joints. DEXION, Ltd. March 12, 1957 [March 16, 1956], No. 8281/56. Class 83 (4). [Also in Group XXV] A jig for producing a frame structure from a plurality of perforated or slotted elements connected by bolt or like connecting means comprises a jig frame and a series of locating members which are applied to or in place of connection means disposed in the jig frame in positions corresponding to the positions of the connection means in the frame to be produced, the said locating members being upstanding from the jig frame and adapted for receiving similarly located connection means to which the elements of the frame to be produced can be applied. In an embodiment the flanges 1 and 12 of slotted L-shaped elements 2 and 13 respectively are bolted together to form the jig. Locating members 22 comprise a cylindrical body having a tapped hole 23 at one end for screwing on to the projecting end of a bolt 20 and at the other end a hexagonal recess 24 and a clearance hole 25 for receiving the head of a bolt to be used in the frame to be produced. If special bolts 26 each having an unthreaded shank portion adjacent the head for closely fitting the round holes in the elements are used with packing washers 28 and 30 a different locating member is required. This locating member 32 is shorter than the member 22 and has a tapped hole 33 at one end and a hexagonal recess 34 with a clearance hole 35 at the other. It is prismatic in shape to easily distinguish it from the other cylindrical locating member. Projections 36 prevent a bolt 20 from being placed in the recess 34 of the member 32 which could result in a reduction in strength of the frame to be produced. The heads of the special bolts 26 are fluted to allow them to enter the recess. The jig may be provided with lay gauges, e.g. an L-shaped bracket 38, for assisting in positioning the frame elements above the jig frame elements. Instead of being provided with tapped holes 23, 33 the lower ends of the locating members may be formed with threaded shanks by which they can be screwed into nuts held below the jig frame. Specifications 620,696, 763,045, 763,056 and 763,057, [all in Group X], are referred to.

Title: Improvements in or relating to electronic numerical accumulators
IPC: H03K23/82
Filed: 1948-03-23
Abstract: 651,086. Counting-apparatus. NATIONAL CASH REGISTER CO. March 23, 1948, No. 8539. Convention date, July 10, 1947. [Class 106 (i)] In an electronic decimal accumulator comprising one or more denominational units, each unit comprises four electronic devices each having two stable conditions and arranged to be operated by the receipt of voltage impulses so as to change from one condition to the other, the devices are connected in series in such a way that at every second operation of one device the next device is operated, input impulses are applied to the first device in the series, and circuits connect the third and fourth devices in the series to the second device so that a change from one condition only in the third or fourth device operates the second device whereby the devices in a unit all return to their initial conditions after the receipt of ten impulses. The denominational unit shown comprises four trigger pairs of triodes A, A<SP>1</SP> ... D, D<SP>1</SP>. The triodes of each pair conduct alternately and the unit can be put in the normal or zero condition, with triodes A<SP>1</SP> B<SP>1</SP>, C<SP>1</SP>, D<SP>1</SP> conducting, by closing switches S. Input negative voltage impulses are applied to the first trigger pair over conductor 61, and upon the receipt of two impulses the pair returns to normal and a negative output impulse is sent over conductor 62 to operate the next trigger pair B, B<SP>1</SP>, and so on. The pairs C, C<SP>1</SP> and D, D<SP>1</SP> have a feed-back connection through rectifiers 65 and 70 with the grid of triode B<SP>1</SP> so that, whenever triode C or D becomes conducting a negative impulse is sent back to cut off triode B<SP>1</SP> and cause triode B to conduct. In this way, the unit returns to zero after ten impulses (instead of sixteen), and the return of the pair D, D<SP>1</SP> causes a negative transfer impulse to be sent over conductor 75. The conduction of triodes A, B, C, D is indicated by glow-tubes 78.

IPC: G01R27/02
Filed: 1964-03-02
Abstract: 1,059,037. Measuring complex impedance. INSTITUT FœR HALBLEITERTECHNIK. March 2, 1964, No. 8683/64. Heading G1U. [Also in Division H1] A measuring bridge comprises a four arm coaxial junction 5' to which three measuring signals are applied by adjustable loops I, II, III. The arms 1', 2', 3', 4' are respectively terminated by the unknown impedance, a standard reactance (e.g. a line of length # #/8), a standard resistance and a null meter. The value of the impedance may be deduced from the ratios of the inputs which are given by their angular settings. According to the invention each loop consists of a fixed and a rotatable part and the total coupling field is the vector sum of the fields provided by both parts. This results in an increased change of angle with coupling field at the low-coupling end of the range and consequently produces greater setting accuracy.

[Class 79 (v)] [See also Group XXVII] The speed of an internal-combustion or other fluid-pressure engine, which may drive a vehicle or machine, is limited to a desired maximum by an electrically controlled clutch mechanism incorporated in the fuel or power supply regulating means. A switch is closed by a speed responsive element to energize a solenoid to disengage the clutch and allow a spring to close a valve restricting the power supply. The accelerator pedal B of a motor vehicle is coupled by rods 11, 15 to a spring controlled lever 16 tending to close the carburetter throttle C. A clutch A couples the rods 11, 15 and a solenoid E lifts a dog 7 from a recess in the clutch-disc 8 when energized by the closure of contacts 17, 22 by a centrifugal device H driven by the speedometer cable J. The contact 22 may be longitudinally adjusted to determine the maximum vehicle speed and a switch 40 may be provided to enable the speed control to be cut out. To enable the accelerator pedal to be used for adjustment of braking when the engine is being employed for this purpose a contact 33 carried by the disc 8 operated by the pedal co-operates with a fixed contact sector 31 to open the control circuit in those positions of the pedal which are concerned. According to the Provisional Specification the solenoid may be operated through a relay and a time switch or stop watch may control the solenoid..

Filed: 1952-04-09
Abstract: 738,162. Valves. FLIGHT REFUELLING, Ltd., and WORLIDGE, R. F. March 30, 1953 [April 9, 1952], No. 9119/52. Class 135. [Also in Group XXVIII] A hose coupling member which is shown in Fig. 4 with its parts as when coupled to a complementary coupling member, is adapted to be closed when uncoupled by a valve 13, which is acted upon by fluid pressure within the hose in a direction tending to open it, a partial counterbalance being provided by a piston 17 on the valve stem 16 working in a closed cylinder 11 supported in the coupling body 10. The valve is manually operated by a rack 22, Fig. 1, and pinion 21, a transverse spindle 18, a crank 19, and a pair of curved links 20, the pinion being arranged in a slot 28 of the valve stem 16 so that, when the valve is closed, the crank is over dead-centre, and is urged by fluid-pressure on the valve against a surface 16a of the stem to prevent the valve opening. The cylinder 11 is vented to atmosphere by a passage (not shown) in the spindle 18. A coupling ring 38, rotatably mounted on one end of the body 10, is connected by arms 44, Fig. 1, with a wheel 45 mounted on the other end of the body, and is adapted for bayonet-type connection with a complementary coupling member 80, Fig. 8. When the coupling is disconnected the coupling ring is locked by a spring-loaded plunger 49 which engages a recess 53 in an internal flange 54 of the coupling ring, and is freed by engagement of the complementary coupling member with a stem 55 on the plunger. The stem engages a slot 56 in flange 54 to limit rotation of the coupling ring. When the coupling is connected, a notch 69, Fig. 1, registers with the rounded end of a slidable bar 67, the other end of which engages a notch 68 in the pinion 21. Actuation of the pinion to open the valve moves the bar to free the pinion and lock the coupling ring, so that the coupling cannot be disconnected until the valve is closed again. The coupling is sealed by a gasket 57, Fig. 8, having a chamfered end engaging a chamfer on a pressure ring 59 mounted on the body 10, a pin 61 permitting axial but preventing rotary movement. Coupling rotation of the ring 38 causes camming action of a lug (Fig. 7, not shown) on the flange 54 and a notch in the ring 59 to compress the gasket against the coupling member 80. A hinged dust-cap 72 has a catch 77 adapted to engage a lug 79 on the body 10. In use, the catch engages the coupling ring 38, the cap fitting into a rubber buffer ring 81 which protects the ring 38.
