Title: Disc record player apparatus
IPC: G11B17/032
Filed: 1981-05-08
Abstract: In a record disc player for e.g. capacitively-read video discs, the turntable spindle (148) is held in engagement with the record centre hole when the turntable (108) is lowered to transfer the record on to receiver pads, in which position the record is aligned with a record retaining spine and can be removed, with the spine, by the insertion of an empty record jacket and its subsequent removal with the record/spine assembly contained in it. A mechanism (192, 180, 178, 162, 164), responsive to the insertion of an empty jacket into the player, retracts the spindle (148) against spring bias (156) to allow insertion of the jacket into the player free from interference with the spindle. <IMAGE>

Title: Lockable handle
Inventor: DALEY ERNEST CHARLES
IPC: E05B5/02
Filed: 1981-08-27
Abstract: A lockable handle device 1 can be operated from outside a closure such as an up-and-over door in an unlocked state and can be operated from inside the closure in the locked state by an over-riding device. Handle 4 when unlocked can be rotated to turn shaft 8 and yoke 9 and hence to withdraw bolts (not shown). In the locked state the handle is held in recess 3, flush with the door, by bolt 6 operated by barrel-lock 7 and engaging in a cut-out of handle shank 5. If bolt 6 is withdrawn by operating lock 7, spring 14 urges the handle to the ejected position. From inside the closure the bolt 6 may be withdrawn by depressing a knob 24 integral with bolt 6 and projecting from housing 17. Inside handle 11 may then be used to lock the handle device from outside, handle 4 is depressed until it is in recess 3, whereupon bolt 6 latches into the shank recess. <IMAGE>

Title: Battery charging circuits
Inventor: NUDDS DERRICK ALFRED
IPC: H02J7/00
Filed: 1981-10-02
Abstract: A battery charging circuit includes means FWR for deriving an unsmoothed DC supply from an AC mains supply, the DC supply being connected by positive and negative supply lines to charging output terminals, a semi-conductor controlled rectifier SCR connected in series in one of the supply lines, a first transistor TR1 connected between the gate of the controlled rectifier and the other supply line for controlling operation of the controlled rectifier SCR, and a second transistor TR2 connected to the first transistor TR1 and to the output so that during charging when the voltage of battery cells connected to the output rises to a desired level the first transistor TR1 prevents operation of the controlled rectifier SCR and charging ceases. The desired voltage level can be adjusted by a potentiometer VR1. The charger gives no output if the battery becomes disconnected during charging, or if the battery is connected with reversed polarity, or if a short circuit exists across the output terminals. <IMAGE>

Title: Wall ties with moisture-trap or drip-promoter
IPC: E04B1/41
Filed: 1982-04-13
Abstract: A straight mid-portion of the metal tie 10 is coated with mouldable material 12, the coating having lateral projection(s) 15 as moisture-trap or drip-promoter 14, intermediate the ends of the straight mid-portion and depending from the tie. Deformation of the metal to produce the moisture trap or drip promoter is thereby avoided, so that there is no stress raiser in the metal to give rise to buckling of the wall tie under compression loads when in use. The coating may be plastics which may be moulded on to the tie as, or together with, the projection; or the plastics may be deformed after coating by hot tools or local heating, or a strip, having bump(s), may be wrapped round the tie. <IMAGE>

Title: Stacking and boxing elongate packages
Inventor: LEAK PAUL ALBERT
IPC: B65G57/30
Filed: 1982-05-11
Abstract: A flow of non-cylindrical elongate packages P is built up into a stack from beneath by counting off a number from the incoming flow, aligning that number of packages into a row having the sides of each package inclined to the plane of the row, and lifting each such lined-up row past a pair of spaced latching supports to build up a stack, of desired height and having successive rows inter-engaged, which is then transferred onto dump flaps and dumped into a waiting box. The same lifting means, e.g. a two-stage pneumatic ram (13, 14), can be used both to lift each row into the stack and to lift the whole stack a further distance for transfer onto the dump flaps. Alternatively elevating bars can perform a repetitive and standardised row-elevating and latching movement whilst a pair of secondary latches, normally level with primary row-latching means, periodically lifts the whole stack for transfer. <IMAGE>

Filed: 1983-05-27
Abstract: A high frequency induction furnace (10) for reflowing a portion of a lightguide preform (44) in order to draw a fiber (52) therefrom. The furnace (10) has a centrally located tubular susceptor (34) therein. A high frequency coil (38) is energized to couple its elecromagnetic field to the susceptor (34) to heat and reflow a portion of the preform (44) in order to draw the fiber (52) therefrom. The susceptor has a thin coating of the preform material (e.g., silica) on at least a portion of the inside surface thereof. In a further embodiment a cylinder (62) is positioned in concentric, spaced relation about the susceptor (34) and is surrounded by an insulating grain (36). A thin coating of the preform material may be additionally provided on at least a portion of either the outer surface of the susceptor or the inner surface of the cylinder. The thin coating prevents contaminating particulates from migrating from small cracks in the inside surface of the susceptor (34) onto the preform (44) while the cylinder (62) prevents small particulate emanating from the insulating grain (36) from being drawn through larger cracks in the susceptor and onto the preform and/or the fiber (52).
