Title: A method of protecting a metallic surface susceptible to abrasion by rock-like material
IPC: B23K35/02
Filed: 1980-03-19
Abstract: A method of protecting a metallic surface susceptible to abrasion by rock-like material, e.g. a surface of a ground-engaging tool or, as shown, a chute, comprises arc stud welding studs (18) of abrasion resistant metallic material to the surface (12) in closely spaced relationship to cause the majority of said rock-like material to contact the abrasion resistant studs instead of the surface. The studs may be cast (e.g. of carbon chromium iron alloy) or of compacted metal powder. A part of each stud to be engaged by stud welding apparatus may be of relatively inexpensive material and connected to an abrasion resistant part by a frangible neck, the former part being broken off following welding of the latter part to the surface to be protected. The welding end of each stud may be provided with a deoxidising aluminium tip or washer. <IMAGE>

Title: Bearings
IPC: F16C29/12
Filed: 1980-05-02
Abstract: A linear ball bearing of the kind which comprises a plurality of tangential or substantially tangential series of recirculatable bearing balls (5) is so constructed and arranged that the bearing balls (5) in those series which are at one side of a strictly radial datum plane (X-X) that contains the axis of linear displacement (3) of the bearing will all recirculate in one direction when the bearing is in use whilst the balls (5) in those series which are at the opposite side of said plane (X-X) will all recirculate in a second and opposite direction when the bearing is in use. An inner sleeve (2) of the bearing which wholly or partly defines the recirculation paths for said series of bearing balls (5) is formed at both of its axial ends with screwthreaded portions for purposes of mounting and/or axial adjustment of the bearing.

Title: System for measuring current position and/or moving direction of vehicle
IPC: G01S11/04
Filed: 1980-08-14
Abstract: A reference station 1 is provided at a fixed predetermined position. (Xa, Ya). The station is adapted to transmit a scanning signal, the transmitting direction of which is scanned in succession in different directions, a positional information signal representative of the position of the reference station and an azimuth information signal representative of a particular azimuth e.g. North.

Title: String instrument pickup system
IPC: G10H3/18
Filed: 1981-02-19
Abstract: A string instrument has a pickup module 16 mounted in a bridge 12 on the sound board 10 of the instrument. The pickup comprises four piezoelectric crystals 28a, 30a, 28b, 30b mounted between a hot connector 34 and ground connector 36, the string saddle 20 bearing on the latter and transmitting compressional stress generated by string tension. The crystals have alternate polarities as shown the two middle ones 30a, 28b having twice the area of the two outer ones 28a, 30b. Thus microphonics are cancelled out by the opposite polarities, and the laterally offset disposition of the strings from neighbouring crystals of opposite polarity provides that horizontal components of string movement are sensed. In other embodiments for solid instruments the saddle is replaced by string adjusters. <IMAGE>

Title: Reinforced collector of the contracted type for a rotating electrical machine
IPC: H01R39/14
Filed: 1981-12-30
Abstract: Two conductive collars 5, 6 are sandwiched between an insulating sleeve 2 and the slip rings 3, 4 on the shaft 1 of a rotary electric machine. Each collar is constructed so as to allow its diameter to be reduced to a certain extent only. Thus, in a contraction process for fitting the slip rings and collars on the shaft, the contraction of the slip rings is absorbed by the collars, once they have closed, and not by the sleeve. The collars 5, 6 possess lateral wings 5c, 6c which connect them to the induction coil of the machine. Each collar is split, e.g as in Fig. 2. <IMAGE>

Patent GB-2113480-A (GB)
Title: Electrical test connector
Inventor: GRAY GEORGE G
IPC: H01R13/22
Filed: 1982-12-03
Abstract: A pneumatically controlled electrical test connector 10 contains spring-loaded pins 34 whose ends are brought into electrical contact with the opposing ends of corresponding connector pins 4 of an electronic module 1 secured and orientated in a support frame 11 of the connector 10. The pins 34 of the pneumatically controlled connector 10 are recessed to centre the ends of the module connector pins 4. Pneumatic cylinders 25 secured to the support frame have piston rods 26 engaged with a slide 20 in which the spring-loaded pins 34 are longitudinally movably mounted, each pin 34 having a collar 36 and a spring 37 trapped between headers 31' and 31'' secured to opposite sides of the slide 20. When actuated, the cylinders 25 draw in the rods 26 and thus produce sufficient force between the opposing pins of the test and module connectors to thereby establish good electrical contact at the contacting pin ends. The spring 37 on each pin 34 accommodates the mechanical tolerances of the pin lengths and causes the force on each pin to be substantially equal. Commercially available connectors 39 are slipped onto the other ends 35' of the test connector pins 34 for wiring of the test connector 10 to a test set. <IMAGE>
