Title: Tab and slot connector means
Inventor: KELLY MICHAEL HERBERT
IPC: F16B17/00
Filed: 1991-07-12
Abstract: A first structural frame member (11) has two tabs (15) projecting from one end and may be secured to a second structural frame member (21) having two slots (25) piercing it intermediate its ends by insertion of the tabs through the respective slots and subsequent deformation of the tabs to prevent their withdrawal from the slots.

Title: Battery charger for mobile apparatus
Inventor: TAKEYASU KENJI
IPC: H02J7/04
Filed: 1991-10-18
Abstract: A timer 3, which controls charging of a battery 6 in a mobile apparatus 100 from a vehicle battery 22, is reset on connection to the battery 22. In order to prevent the battery 6 from being overcharged due to timer 3 again being reset following a temporary reduction and subsequent recovery of the voltage of battery 22 on operation of a starter motor 21, the timer 3 is arranged to be powered from battery 6 via a transistor 15 during such temporary reduction. Transistor 15 is turned on by a transistor 12 following charging of a capacitor 11 from battery 22, and capacitor 11 maintains transistor 12, and thus transistor 15, on during the temporary reduction. The apparatus 100 may be a mobile telephone or a cordless telephone, shaver or iron. <IMAGE>

Patent GB-2262077-A (GB)
Title: Single file feeders
Inventor: PEDERSEN BJORN HEIDE
IPC: B65G47/14
Filed: 1992-11-20
Abstract: Randomly discharged irregular pieces from a store of partly congealed deep frozen food are delivered to the central area of a revolving table (4), immediately above which there is disposed an essentially stationary spiral-shaped body (6) which due to the rotation of the table conducts the pieces outwards, thereby increasing their mutual distance, in order for them to be discharged in a single file to a conveyor (28). The spiral-shaped body (6) is supported and driven to perform a horizontal shaking movement thereby disintegrating congealed lumps of food, so that their constituent parts may equally be distributed evenly along the spiral track. In case the pieces at full capacity are discharged without mutual separation such a separation may be obtained by discharging them to a conveyor (28) having a speed which is faster than the peripheral speed of the rotating table. <IMAGE>
Patent GB-927381-A (GB)
IPC: D06F49/00
Abstract: 927,381. Spin-driers. POENSGEN G.m.b.H. GEB. April 21, 1960 [April 27, 1959], No. 13964/60. Class 34 (2). A spin-drier comprises a drum 7, Fig. 1, rotatable by a motor 8, a removable cover 9 lockable on and rotatable with the drum, an insert 22 in the drum and in raisable relation thereto to remove dried washing, and an outer cover 1 hinged to the drier and raisable by an hydraulic piston and cylinder 3, 4, characterized in that the cover 9 is raisable together with the cover 1 and the cover 9 is lockingly disengageable and engageable with the drum by means provided on the cover 1. Referring to Fig. 3, the cover 1 is provided with a sleeve 16 slidable vertically in the cover by means of a toggle 17 operable by a push-rod 20 in an hydraulic cylinder 21 pivoted to a yoke 19 on the cover 1, the toggle also being pivoted at 18 to the yoke. Within the sleeve is a vertically-movable pin 13a having a tapered shoulder 13b, co-operating with a correspondingly shaped portion of the sleeve, and a tapered portion 13 co-operating with two radial locking-bars 10 under the urge of springs 11 on the cover 9. The pin 13a is slidable in a boss 12 on the cover 9 and has grooves 15 engaged by bolts 14 on the boss to prevent removal of the pin from the boss. When the toggle is moved to the position shown in Fig. 1, the pin 13a is moved downwardly and the taper 13 passes through an aperture in the cover 9 whereby the bars 10 are moved outwardly to lock the cover to the drum. The sleeve 16 is slightly lifted relative to the taper 13b as the toggle passes through dead centre whereby the taper 13b does not contact the sleeve and the drum and its cover can rotate freely. The insert 22 is carried by a rod 24 rotated with but slidable in a sleeve shaft 24 driven by the motor 8, the rod being variable when desired by hydraulic pressure in the bottom of the shaft 24 as described with reference to Figs. 5 and 6 (not shown). In another embodiment the toggle 17 is operable from the hydraulic cylinder 4 instead of by a separate cylinder 21, as described with reference to Fig. 7 (not shown).

Title: Thermal fluid recptacle combined with cup
Inventor: COX KINGSLEY JAMES ARTHUR
IPC: A47G19/22
Filed: 1994-07-12
Abstract: A thermal fluid receptacle, e.g. a vacuum flask, comprises a complete unit which is subdivided into a main fluid container A and a cup compartment B. Fluid from the main container may pass into the cup compartment by depressing a switch H to open stopper G between the main fluid container and the cup compartment. Another switch J located on the cup operates a stopper F on the top of the cup compartment allowing fluid in the cup to be via an aperture E. Thus, the above receptacle enables fluid to be moved from one compartment, which may be heated, cooled, or enclosed by a vacuum, to another compartment all within the same receptacle, when the receptacle is inverted. The cup may be transparent. <IMAGE>
