Patent GB-2151949-A (GB)
Title: Worm separation equipment
Inventor: PRICE JAMES STANLEY
IPC: B07B13/00
Filed: 1984-12-21
Abstract: An apparatus 10 for separating worms from a worm-containing medium comprises an upwardly-moving belt 12 fed with the medium from a hopper 14. The hopper 14 and subsequent belt 18 co-operate with the upper surface 16 of conveyor belt 12 to break up lumps in the medium and the brush 20 lightly brushes the surface 16 to remove loose material from the belt 12. By this stage however, the worms in the medium will be gripping the surface 16 and they are only dislodged from the belt for discharge into a bin (not shown) when they reach the scraper 22. In an alternative embodiment 110, the separator comprises an inclined plate 114 which is vibrated to move the material past a number of endless driven wires 116 having upwardly moving runs passing through appropriate apertures in the plate. Worms in the material become draped around the upwardly moving runs of the wires and are carried upward astride the wires for removal prior to reaching the top wire-supporting roller. The substantially worm-free material sliding off the bottom end of the plate is taken away by a cross-conveyor 124. <IMAGE>

Patent GB-2168417-A (GB)
Title: Shackle mechanisms
Inventor: BELLINGHAM RONALD SIDNEY
IPC: E05B75/00
Filed: 1985-11-18
Abstract: An "arrest" handcuff has the usual ratchet and pawl mechanism for closing the wrist aperture. In order to deadlock the pawl (10) a runner (16) is shifted by means of a manual push-button (22) extending from the back face of the runner so that a stump (19) on the runner then overlies the nose (23) of the pawl. To release the deadlocking and pivot the pawl clear of the ratchet the runner (16) must be shifted to the left, which movement is normally blocked by a lever pack (25) operating on the runner stump (21). A correct key, however, can lift the levers and turn the runner back. If the option to deadlock the pawl is not taken up in any particular arrest situation the pawl still remains engaged with the ratchet under its spring bias (13) and the correct key is still needed to perform a leftward movement of the runner to lift the pawl from the ratchet.

Title: Trolley pole raising and lowering apparatus
Inventor: GRIFFITHS THOMAS WILLIAM
IPC: B60L5/12
Filed: 1986-07-21
Abstract: A trolley pole (10) is supported on a vertical shaft (52) so as to be rotatable from side to side while in its elevated, operating position. The shaft is supported on a support structure including a pivot plate (40) which is tiltably mounted on a base plate (25) on a vehicle (12). The pivot plate can be tilted by extending the arm (37) of a linear actuator (33). When the pivot plate is tilted, the pole is lowered and centered, and a gravity-operated latch structure (62-68) comes into effect to maintain the pole centered whenever it is not in its operating postion.An electrical control circuit (Figure 6) for operating the actuator is also disclosed.
Patent GB-2181621-A (GB)
Title: Electro-mechanical transducer
Inventor: JONES THOMAS GRIFFITH
IPC: H04R17/00
Filed: 1986-01-21
Abstract: An electro-mechanical transducer has two layers (20) of a polarised piezoelectric polymer coated on each face with a conductive coating (22). The two layers are arranged back to back and secured by a double-sided adhesive tape (24) with their positively charged conductive coatings facing each other. As the protective layers (26) of insulation and a protective sheath (28) are provided. The inner conductive coatings are interconnected by a pin (30) passing through the polymer layers with the outer conductive coating being omitted in the vicinity of the pin. The outer conductive coatings are likewise interconnected by a pin (32), connection to an external screened cable being made through these pins with pin (32) being connected to the outer screen of the cable and pin (30) to the inner signal wire. Because the device is piezo-electric no external power supply is required and interconnection of the two inner conductive coatings enhances the signal generated by the device while the two outer coatings act as an electro-magnetic and electro-static screen to reduce extraneous and unwanted spurious signals which would otherwise affect operation of the device.

Patent GB-2198574-A (GB)
Title: Audio deck controller
Inventor: DENNER MICHAEL JAMES
IPC: G11B27/10
Filed: 1987-12-01
Abstract: The musical beat frequencies of two or more audio signals from decks 10, 11, are measured and made equal, if possible, and brought into phase agreement. The system operates by using processors 17 to measure the beats-per-unit time of each of the two audio signals converted to digital form, and producing control signals dependent on a comparison in a main processor 22. The control signals alter the speed of one of the decks, thus altering the beats-per-unit time of the corresponding input from the deck whose speed has been altered. An alarm system, actuable when the difference in beats-per-unit time of the two inputs exceeds a predetermined level, prevents control which involves excessive changes in pitch of the music. The system is used to provide compatibility between the beat of a piece of music ending on one deck and that of another beginning on a second deck. <IMAGE>

Title: Man-propelled vehicle
Inventor: CHARVILL ROBERT LEWIS HEAP
IPC: B62M1/24
Filed: 1988-12-01
Abstract: A man-propelled vehicle has a wheeled chassis incorporating footrest assemblies having single or double seating arrangements (the double arrangement is shown in Fig. 1) to initiate the energy supply. The footrests move longitudinally and in one plane only. They are also interconnected by means of an arrangement of multiple gears 10 and associated gear teeth incorporated in the footrest assembly 11. By this means a pull/push action is carried by a single connecting rod 8 to an adjustable lever 9 on a toothed quadrant (not shown). This provides adjustable leverage (gearing) as required. The quadrant is connected directly to the ratchet housing 4 and when in operation the outward facing ratchet 5 engages teeth in the outer worm drive 2, restricts rotary movement of the outer worm drive 2, restricts rotary movement of the outer worm drive (in association with thrust bar 6) thereby transferring the energy supply by means of the ball-bearings to the inner worm drive 3 to turn the axle in the required direction.   <IMAGE>

Title: Bag manufacture
Inventor: FUHER REGINALD SAMUEL
IPC: B26D5/30
Filed: 1989-02-09
Abstract: The apparatus enables bags to be made accurately from a continuous strip 12A of heat sealable material. A sensor 34 detects print registration marks on the strip 12A which is cut by a knife 14A. A transducer on nip rollers 16A provides pulses as the rollers turn to control means which after a predetermined count actuate the knife 14A. These pulses are also counted to determine the length between print registration marks detected by the sensor 34. This count is then used to determine a second value for the predetermined count for actuating the knife 14A to provide an accurate cut. <IMAGE>

Patent GB-2232490-A (GB)
Title: Torque measuring arrangements
Inventor: J RGENSEN GEERT
IPC: G01L3/10
Filed: 1990-06-07
Abstract: An arrangement for measuring torque comprises a shaft (1) with a section (3) of reduced diameter, a sleeve (2) secured to the shaft at each side of the reduced diameter section in a manner preventing rotation and axial displacement relative to the shaft, which sleeve carries an armature (12) which, in use, upon rotation of the two ends of the sleeve relative to one another, is displaced axially and changes an electric and/or a magnetic field, and means for detecting the change in the field(s). In order to make the output signal of such a torque-measuring arrangement greater, the sleeve (2), considered axially, is sub-divided into two parts (4, 5) by a pair of diametrically opposed notches forming tongues (6, 7) in the sleeve, and the armature is secured to ends (10, 11) of the tongues. 
<??>As described the armature (12) is magnetic and its axial displacement alters the relative coupling between a primary (14) and two secondary coils (13, 16) supported around the sleeve. Various ways of correcting for axial shaft movement are described.
