Title: Transducer simulator
Inventor: LINFORTH ARTHER JOHN
IPC: G01D18/00
Filed: 1981-10-31
Abstract: Apparatus for simulating a transducer in which movement of a component produces an electrical output signal indicative of the position of the component, comprises a reference transducer 11 having nominally the same operating characteristics as the transducer to be simulated and having a movable member, the movement of which produces a varying output signal. Means are provided for moving the member in a path including positions 1, 2, 3, 4. Adjustable stops 22 selectively arrest the movement of the member at one or more of positions 1, 2, 3, 4, thereby causing the reference transducer 11 to produce respective reference output signals when the member 12 is at each position 1, 2, 3, 4. The stop means 22 are adjusted so that the movable member is slightly displaced from its "nominal" position to a position in which an output is derived similar to that of which an ideal transducer would provide at the "actual nominal" position. <IMAGE>

Title: Musical scale indicator
Inventor: THORBURN DUNCAN GLEN
IPC: G09B15/00
Filed: 1982-04-27
Abstract: In a musical scale indicator which is constructed along the lines of a sliderule, the (fixed) sleeve has fret (2) and string (1) markings in and adjacent a "window" which represents the guitar fingerboard. There is a smaller "window" (4), called the key indicator, giving the key information. Within the sleeve, and within the larger window, is note information (3) of all the notes on the guitar fingerboard with the represented guitar in regular tuning. The notes are represented in white for natural notes, and in black for sharps and flats, which is a useful way of displaying the information to musicians who also play keyboards. The inner (movable) slide has a selection of holes to enable the relevant notes to be displayed. Around the holes is block pattern information, necessary to instruct the player to play the scale stepwise within a limited area on all the strings. There is code information also on the slide to clarify the information on the block pattern scales. <IMAGE>

Title: Riveting machine for brake linings
IPC: B21J15/30
Filed: 1982-05-19
Abstract: In a machine for riveting brake linings onto brake shoes, rivets are fed consecutively to a top dolly (10), which after the introduction of a rivet into a workpiece, performs the rivet deformation conjointly with a stationary bottom dolly (11).

Title: Playing ball construction and games therefor
Inventor: MCNEILL LOCKSLEY D
IPC: A63B43/04
Filed: 1982-09-23

The balls may have a fixed weight so that bias can be applied when rolling such as required for a lawn bowling type game. When used with steel shot or the like, they can be played onto a magnetized board which will hold them in place or alternatively, a flexible fabric or plastic bag type ball can include steel shot or the like and can be pitched onto a magnetized board.
Patent GB-2135543-A (GB)
Title: Modulation meters
Inventor: WALKER CHRISTOPHER JOHN
IPC: H03L7/14
Filed: 1983-02-17
Abstract: A modulation meter comprises a phase-lock loop receiver with storage means for maintaining lock despite loss of received signal, the loop including a mixer 21 arranged to mix frequency outputs from a comb generator 22 with the received signal 24. The difference frequency from the mixer is passed through gain control circuitry 30-32 and is locked to a predetermined frequency fREF by comparing in a frequency detector 34. The error is converted into a voltage for application to a voltage controlled oscillator 23 to shift the frequencies of the comb generator 22. The direction of the shift is evaluated by using a phase detector 36 to examine the actual phase relative to the predetermined frequency. The voltage and shift direction for application to the comb generator 22 are sampled and held in sample-and-hold units 39 and 37. In this way the modulation meter locks onto a carrier frequency of a received signal and a hold signal 33 is then applied to all sample-and-hold units, so that when the received signal is terminated and reappears the modulation meter is already locked on to the carrier frequency. <IMAGE>

Title: Hall effect module for loop detector
Inventor: DYER MICHAEL PHILIP
IPC: H04M3/22
Filed: 1983-09-15
Abstract: A Hall effect module for responding to the looped/unlooped state of a line follows the basic principles of our Patent No. 1478219. However, its magnetic circuit is basically that of the well-known 3000- type relay, so that it can readily replace such a relay used as the A-relay in a register. In the present arrangement the coil 1, core 2 and yoke 3 are exactly as in the standard relay. The pile-up and armature are removed and replaced by a module 4, which includes a Hall sensor and a piece of soft iron to complete the magnetic circuit. <IMAGE>

Title: Lift shaft lighting control
Inventor: BUCK LESLIE JOHN
IPC: H05B37/02
Filed: 1985-07-10
Abstract: Lamps (10), (Figure 1), illuminating a lift shaft are energised in response to a lift car top inspection switch (16), (Figure 2), being switched to the inspection position, and in response to a pit on/off switch (38), (Figure 4), being switched to an off position. The top inspection switch and the pit on/off switch have the conventional functions of respectively disabling use-operable lift control buttons so that an engineer has sole control of lift movement, and of enabling the engineer to immobilise the lift completely when entering the shaft beneath the lift car. The lamp control circuit may have relays 40, 42 connected in energisation circuits 44, 46 respectively associated with the top inspection switch and the pit on/off switch, the relays having respective contact sets 48, 50 connected in parallel in the lighting circuit. An alternative arrangement, (Figures 2 to 4), uses only one relay the energisation circuit of which includes series connected switches respectively associated with the top inspection switch and the pit on/off switch. <IMAGE>

Inventor: WHITE RONALD LESLIE ALBERT
IPC: H02G3/06
Filed: 1985-08-01
Abstract: A cable ladder system comprises cable ladders with abutting stringers 1 and secured together by connecting members 20. Longitudinally extending marginal portions 31, 32 of each connecting member 20 are of such a shape that they interengage with longitudinally extending marginal portions of the adjacent end portions of a pair of aligned stringers 1 to effect a snap fit between the connecting member and the end portions of the stringers and parts 29 and 30 of protrude through holes 21 and 22 to prevent relative lengthwise movement between the stringers and the connecting member. No separately formed bolts or rivets are employed and the connecting members 20 are of such a construction that they can be readily hot dipped galvanised without risk that the galvanising will hamper securing of the connecting members to the stringer 1. <IMAGE>
