Title: Apparatus for sealing film webs
Inventor: MUNDUS FRIEDHELM
IPC: B29C65/00
Filed: 1993-04-20
Abstract: Apparatus for making spaced linear seals between two superposed webs of thermoplastic material by using heated bars (10, 11) which are movable towards each other to squeeze the superposed webs (20) together. A separating sheet (12) of, e.g., Teflon, is provided to lie between the bars (10, 11) and web (20) to prevent them sticking together. When the bars (10, 11) are separated they can remain heated to improve efficiency but to avoid this melting the web (20) remaining between them the separating sheet is positioned spaced between the bars (10, 11) and web (20) to form two heat insulating air gaps.

Title: Electric inverters or converters
Inventor: CASWELL BRIAN
IPC: H02M3/00
Filed: 1993-11-19
Abstract: A housing 13 of the inverter or convertor 10 and input and output terminals 17 - 21 are arranged such that a single connector 11 can be connected or disconnected from the input and output terminals. The input and output terminals are provided by five male connectors 17, 18, 19, 20 and 21 that project from the sealed housing 13. A single plug connector 11 has female connectors 23, 24, 25, 26 and 27 that cooperate with the male connectors. d.c. input power is supplied to the inventor by the connectors 23 and 25 to the male connectors 17 and 19. Power to a fluorescent tube is supplied from the male connectors 18 and 20 to the female connectors 24 and 26. In a further aspect, the connector 11 has two positions so that depending on the way round that it is plugged in, one or the other of two different power sources may be connected. a.c. input power can be supplied into the connectors 19 and 21 by reversing the orientation of the plug to the housing. The output is then from the same male connectors 18 and 20 via the female connectors 26 and 24 respectively. A transistor inventor circuit is described (Fig. 4) which enables operation on 12/24 volts a.c. or d.c. The fluorescent light (14, Fig. 3) may be used in association with a drinks dispenser of a bar display (30). <IMAGE>
Patent GB-2278248-A (GB)
Title: Fuel injector driver with OFF current prevention
Inventor: MATSUURA TAKASHI
IPC: F02B1/04
Filed: 1994-05-20
Abstract: Because the low logic level of gate 78 may not be exactly zero, comparator 75 acting through amplifier 74 and transistor 70 may cause a small current to flow in resistor 71, and hence injector 8, when the input signal 76 is low. This may cause fuel leakage through the injector in a high-pressure direct injection system. To prevent this, comparator 83, which has an open-collector output, disables transistor 70 when input signal 76 is low. Monostable 77 and transistor 73 provide an initial high-current output. A high-side driver is described. <IMAGE>

Title: Preparation of acicular magnetic iron oxide coated with cobalt ferrite
Inventor: SCHWAB EKKEHARD
IPC: C09D5/23
Filed: 1994-08-17
Abstract: Acicular cobalt-containing magnetic iron oxides having a high coercive force and a core/shell structure and hence a low temperature-dependence of the coercive force are prepared by a process in which, in a first stage, surface activation is effected by means of iron(II) and cobalt(II) ions under alkaline conditions on the iron oxide core under an inert gas atmosphere and thereafter, in a second stage, an epitactic coating of cobalt ferrite is formed oxidatively from iron(II) and cobalt(II) deposited from a further addition of iron(II) and cobalt(II) ions in solution hydroxide, likewise under alkaline reaction conditions. The total amount of cobalt ions used for doping remains unchanged compared with the known doped iron oxides or is even smaller. In the second process stage, the achievable coercive force can be controlled by the proportion of air in the gas mixture during the formation of the epitactic coating.
Patent GB-2292969-A (GB)
Title: Handle mechanisms
Inventor: DOLMAN TERENCE JAMES
IPC: E05B13/10
Filed: 1994-08-31
Abstract: A handle mechanism comprises a base 10 and a handle 11 that is rotatable on the base. The handle includes a lock 17 which has a bolt 31 for engagement with the base to lock the handle to the base so preventing rotation of the handle. The bolt can be moved out of the locked position by a push button 20 which is pushed into the handle to release the bolt. This is achieved by a mechanism interposed between the push button and the bolt which translates movement of the push button in one direction into movement of the bolt in an opposite direction. An arm 33 is provided that forms a latch holding the bolt out of the locked position as the handle is rotated but permitting automatic return of the bolt to the locked position when the handle is moved to the closed position. <IMAGE>

Title: Method and apparatus for depositing a textile fibre sliver in a can
Inventor: HOESEL FRITZ
IPC: B65H54/76
Filed: 1995-08-09
Abstract: In a method for depositing textile fibre slivers in fibre sliver cans, in particular at a carding machine or draw frame, fibre sliver is introduced by way of a rotating delivery head (17) in a coiled configuration into the fibre sliver can (27). To enable the sliver end to be arranged at a predetermined point of the can and for an exactly predetermined total amount of sliver to be deposited, the rotary movement of the delivery head is stopped at a position of the can which corresponds to a predetermined total amount less a linear sliver amount, the can is moved away as production of linear fibre sliver is continued and the fibre sliver is cut through after a predetermined production of linear fibre sliver. <IMAGE>

Title: Differential weight security alarm
Inventor: WILLIAMS PHILIP ELPHEE
IPC: G08B13/14
Filed: 1995-10-07
Abstract: The differential weight security alarm consists of a rigid surface A bearing on piezo-electric sensors C under deflection which provide an output signal as a result of the rate of change of weight experienced by the placement on or removal of an object from the surface. This signal is sent to an electronic unit (Fig. 7) which filters, amplifies and produces an output signal as well as resetting the apparatus in preparation for a subsequent event. The phase of the output signal may also be determined to tell whether an item has been placed on or removed from the surface.
