Title: Tensile testing apparatus
Inventor: LEECH JOHN RODERIC
IPC: G01N3/08
Filed: 1967-05-10
Abstract: 1,215,603. Tensile testing machines. COURTAULDS Ltd. May 9, 1968 [May 10, 1967], No. 21816/67. Heading G1S. Apparatus for testing the tensile strength of filamentary material comprises a pair of relatively movable arms 38, 39 for gripping the opposite ends of a filament in combination with apparatus 12 for loading the filament on the arms. A number of filaments are mounted on a tape positioned in a container 19. The container 19 and the loading apparatus 12 are mounted on a common support to enable them to be pivoted towards and away from the arms 38, 39. With the loading apparatus adjacent the arms 38, 39, the loading end of the tape is drawn in front of a sliding member 42 by manually moving a finger piece (22), Fig. 1 (not shown). A spring loaded hard grip 25 and a handle 24 are then manually gripped so that sliding members 35 of a saddle 31 are moved downwards causing their upper and lower projections 36 and 37 to engage projections 58 on the arm 38 and channels 80 in a block 68 attached to the arm 39. The loading apparatus is thus locked to the arms. Simultaneously the sliding member 42 is moved towards the arms so that pegs 59, 81 enter bosses 44. This movement causes the pegs to pass through a pair of holes in the tape on which the filament is mounted and simultaneous movement of cutting edges 43 of the member 42 severs a portion of the tape with a single filament. On releasing the hand grip the tape loading apparatus may be moved away from the arms 38, 39 leaving the tape with the filament impaled on the pegs 59, 81. To clamp the lower end of the filament, a cam 67 attached to a rod 64 is rotated by a handle 66 thus allowing a lever 69 to rotate in a clockwise direction. The movement of the end 71 of the lever allows a nylon faced jaw 74 supported by a member 73 to be urged away from the arm 39 by a spring 75. At the same time the peg 79 of a hook shaped arm 77 slides in a groove on the cam 67 to move the arm, which has a nylon faced jaw 76, to the front of the block 68. The spring 75 therefore clamps the filament between the jaws 74, 76. To clamp the upper end of the filament, a member 52 is pushed downwards until its jaw 51 contacts a spring loaded jaw 47 on the arm 38, the jaw 51 being held in position by a pawl 54 engaging a notch 56 on a wheel 57. The arm 38 is attached to a part 60a of a load cell for measuring the load on the arm.

Abstract: 1,173,658. Vehicle levelling device. F. S. ALLINQUANT. 11 May, 1967 [26 May, 1966], No. 21873/67. Heading B7D. [Also in Division F2] An oleopneumatic suspension system comprises a plurality of struts 1 each located adjacent a vehicle wheel between sprung and unsprung masses thereof, said struts each consisting of a piston 3 with an articulated piston-rod 3a in a cylinder 2, the cylinder chamber 4 above the piston being filled with oil and communicating with a pneumatic suspension spring 5 via clamping foils, wherein the intake of oil into each strut is controlled by a valve means 8 combined with the strut from a reservoir 166 which supplies all the struts via lines 10 and 11, the valve means 8 being operated by pressure variations brought about in the. strut by variations of its length. The valve means 8 is fixed within chamber 4 and has longitudinal bores 37, a piston 47 having a rod 49b adapted to seat on a member 43, a chamber 52 communicating with line 10, a chamber 58 communicating with chamber 4, a chamber 59 communicating with atmosphere, and a chamber 60 adapted to communicate with a port 64 in cylinder 2 via a space 63 in the cylinder wall. Ports 6 and 6b in the cylinder wall also intercommunicate via a space 6a. If the piston is extended below port 64 the pressure in chamber 4 via space 63 causes the piston 47 to move up so that rod 49b cuts off the supply of pressure oil. When the piston is above port 64 chamber 4 is always connected to the source of pressure oil. If the piston is below both ports 64 and 6 then the oil from chamber 4 will pass into chamber 7 via space 6a and port 6b, and then to reservoir 16b. The reservoir is supplied with oil by an enginedriven pump 19 via a manostatic gate valve 20 and non-return valve 21. An enclosure 18 of the reservoir contains compressed air.

Filed: 1939-07-27
Abstract: 532,705. Selective distant control. TELEFUNKEN GES. FUR DRAHTLOSE TELEGRAPHIE. July 27, 1939, No. 21878. Convention date, July 28, 1938. [Class 40 (i)] In a system in which a direction finding aerial or the tuning element of a wireless set is controlled from a distance by means of a transmitter which sends positive and negative impulses over a number of circuits to vary the direction of the resultant field at the receiver, synchronism is indicated by causing the distant aerial &c. or a member.geared to it to send back a signal in a pre-determined position. As shown, the receiver 33 drives a cam which opens a contact 45 once in each rotation to cause a discharge in a circular neon tube at the transmitter. The discharge, which is visible through a slot rotated by the transmitter, should occur when the slot is opposite a pointer 41. To guard against the giving of the signal in the synchronous position when in-fact the transmitter and receiver are a whole revolution out of step the slot and the cam are driven at a different speed from the transmitter and receiver. The number of code combinations can be increased by varying the strength of the impulses by means of resistances.

Abstract: 1514965 Anti-sway systems; anti-skid systems MOTOR WHEEL CORP 22 May 1975 [23 May 1974] 22164/75 Heading F2F A system for correcting horizontal sway of a trailer vehicle comprises a transducer at each of two opposite wheels, Fig. 12, a frequency/ voltage converter for each wheel, a differential amplifier 68 to provide a signal which is a function of the difference in the wheel speeds consequent upon the difference in radii of their paths on the road surface, a sway-rate amplifier 238 for amplifying that signal, and a brake driver amplifier 242 for applying, or increasing application of, the brakes simultaneously-the greater the speed difference the greater the brake application, to increase the drag on the trailer and thereby correct the sway. A lowspeed lockout circuit 234 inhibits activation of the rate- and driver-amplifiers to permit unbraked manoeuvring at low speeds. The operator can apply the brakes through controller 44, which overrides the automatic system if the controller calls for the greater braking effort. A combined sway-correcting and anti-skid system comprises transducers, converters, differential amplifier, sway-rate amplifier and lowspeed lockout circuit, Fig. 16, as before, but now provision is made also for skid control following application of the brakes. A circuit 70 for detecting a lockup of one or both wheels and for enabling the brakes to be applied when the trailer is travelling at a speed less than the locked wheel detection threshold, is now arranged in parallel and in series with differential amplifier 68; separate anti-sway and anti-skid brake driver amplifiers 296, 298, are provided, and a mode selector 302, whose function is to inhibit one or other of these, is in series with a controller circuit (not shown) which is governed by application, or otherwise, of the trailer brakes or those of the tractor vehicle: any brake application inhibits antisway driver 296; otherwise, anti-skid driver 298 is inhibited. An anti-skid system providing for release of the brakes of two wheels at opposite sides of a vehicle simultaneously, without a swaycorrecting system, may be provided. The brakes are preferably electrically-operated, but may be pneumatic or hydraulic.

Filed: 1934-07-31
Abstract: 440,665. Electromagnetic switches. WESTON ELECTRICAL INSTRUMENT CORPORATION, 614, Frelinghuysen Avenue, Newark, New Jersey, U.S.A.-(Assignees of Lamb, A. H. ; 402, Chilton Street, Elizabeth, New Jersey, U.S.A.) July 31, 1934, No. 22281. Convention date, June 29. [Class 38 (v)] An electromagnetic relay arrangement for use in electric control or alarm systems in which contacts in the circuit of an electric motor are closed by the displacement of the movable part of a control device sensitive to an operating condition, a holding switch being provided to maintain circuit for the motor independently of said contacts, a single cam member having a plurality of cam surfaces is adapted to actuate pusher means for opening the contacts of the control device and also said holding switch and the load or alarm circuit switch. As shown in the Figure, the control device, which may be operated for example, in accordance with variations of light, heat, humidity, &c., supplies current to the movable coil 2 of a sensitive instrument movable between permanent magnet polepieces 1. The indicator 3 of the instrument carries a small magnetic armature and when deflected towards the left comes within the range of attraction of a small permanent magnet 5. The members 4, 5 act as contacts and complete the circuit of a small motor 7 which drives a cam disc 9 through gearing 10. During the rotation of the cam disc 9 an independent energizing circuit for the motor is completed at contacts 16 operated by the shaped periphery of the cam and the instrument contacts 4, 5 are disengaged by a pin 13 on a double lever 12, 14 which is operated by a pin 15 on the cam disc. During the rotation of the disc a cam 23 on its rear face engages an arm 20 of a pivoted carrier for a mercury switch thus causing the tilting of the switch 17 in the controlled circuit. This may bring an alarm into operation or may exercise a control function as, for example, by switching in or out resistances in a heating circuit. The apparatus may be modified for operation at upper as well as lower limits by the provision of a further fixed contact on the control instrument and by suitable modification of the motor-driven cam mechanism, (Fig. 2, not shown). In such a modification operation at one limit must be succeeded by operation at the opposite limit. If operation at either limit indiscriminately is desired, two separate control instruments are employed, (Figs. 3 and 4, not shown).
