Title: Screwdriver
IPC: B25B23/14
Filed: 1982-04-08
Abstract: A screwdriver which has a leading edge (21) which is adjustable relatively to a surface (20) and has a dog clutch (8) through which it may, for example, be operated from an electric motor, the clutch comprising cooperating members (2,9) individually carrying dogs (7) and counter dogs (7') respectively of contrasted heights, whereby the bit (18) of the tool can be turned through a predetermined screwing travel until coacting lateral flanks (30,30') of the dogs jump one another. To cater for a simple and time-saving changeover from screwing-in to screwing-out of a screw (19) when required, provision is made for greater applied torque during the latter by having the maximum effective contact faces (31) of the cooperating dogs greater during left-handed than during right-handed rotation. <IMAGE>

Title: Crystal growth
Inventor: GOODMAN COLIN HOWARD LUDLOW
IPC: C30B19/12
Filed: 1982-04-27
Abstract: The temperature range of operation of liquid encapsulated Czochralski crystal growth from the melt is extended to a new lower temperature range by the use of fluoride glasses. The use of these glasses to permit liquid phase epitaxy from volatile solutions is also described, as is their use to protect seed-substrates from decomposition before they become covered by the growth melt, covering the surface of the melt or solution with a layer of an inert fluoride glass having a viscosity of not more than 60 poise at the temperature of the melt or solution to inhibit volatilisation.

Title: Self-locking belt reeling mechanism for safety belts
IPC: B60R22/405
Filed: 1982-04-28
Abstract: A self-locking belt reeling mechanism for safety belts for motor vehicles has a belt winding spindle (4) which bears a profiled member (9) provided with stops for a locking member (11) mounted thereon. The locking member (11) has teeth engageable with a toothed portion (15) fixed to the housing (1) when the locking member (11) is deflected onto a locking position, the locking member (11) being coupled to a spring-loaded plate cam (17) which is also mounted on the spindle (4) and rotates therewith. Rattling noises of the mechanism are reduced by means of a resilient connection which resiliently clamps the locking member (11) to the plate cam (17) which connection conveniently includes a peg formed on the plate cam (17) and abutting on the outer periphery of the locking member (11). Noise reduction may be improved by providing the peg with a rubber O-ring which abuts on the periphery of the locking member. <IMAGE>

Title: Universal piercing device
Inventor: BALISTRERI THOMAS W
IPC: B67B7/48
Filed: 1982-07-29
Abstract: A universal piercing device for vented and unvented I.V. administration sets comprises a spike 100 having ports 105, 107 for liquid and air respectively. In use, the spike is inserted sufficiently through the seal of the I.V. container to expose only port 105 for unvented systems or to expose bolt ports for vented systems. A hydrophobic filter 112 is used to prevent the passage of liquid from the vent, but allow the passage of air. In another embodiment, an air vent passage exposed to the interior of a container is blocked when the device is used in a non-vented system. In the device of Fig. 13 there are two spikes and the air vent spike is not used in a non-vented system. In a further device (Fig. 14), two passages 604, 605 open into a drip chamber 607 provided with a vent winder 609 covered by a hydrophobic filter 610. <IMAGE>

Title: Peripheral toroidal blowers
Inventor: MIDDLETON ANDREW HENRY
IPC: F04D23/00
Filed: 1982-09-07
Abstract: The blower has a toroidal chamber 1 divided along a plane at right angles to its axis into a first chamber part bounded by a stator housing 2 having adjacent inlet and outlet ports with a stripper between them and a second chamber part bounded by a rotor housing 6 containing a series of impeller blades 7. A channel 19 extends circumferentially around the toroidal chamber 1 and communicates with the toroidal chamber through the peripheral clearance 20 between the rotor and stator housings. Droplets of condensate produced when hot flue gases are pumped by the blower collect in the channel 19 and are removed by way of a drain pipe 21. The rotor and stator housings are preferably of die cast aluminium. A plurality of relatively small air bleed holes 25 act to ventilate a space 24 in which a motor 23 driving the rotor housing 6 is accommodated and thus prevent the entry of hot flue gases. <IMAGE>

Title: Improvements in or relating to microwave circulators
Inventor: HALL PETER SCOTT
IPC: H01P1/387
Filed: 1982-09-20
Abstract: A microwave circulator for use in MIC's comprises an insulating substrate (1) backed by a ground- plane (2) and having a circular disc (3) of metallising on its opposite surface from whose periphery extend strip transmission lines (7). A ferrite disc (5) of larger diameter than disc (3) is secured concentrically over the latter disc (3) and has a metallising layer (6) on its free surface. The line-portions (7) below the ferrite disc (5) are narrower than the line-portions (4) extending beyond its periphery to maintain constant impedance. The shoulders between these two line-portions aid location of the ferrite disc (5) during manufacture, and this circulator reduces tolerance problems generally. <IMAGE>

Title: Constant current source
Inventor: DORFMEISTER GEORG
IPC: H02J7/02
Filed: 1984-04-02
Abstract: A circuit for operating a load, for example, for charging an accumulator 7, from a blocking-oscillator-type converter comprising a transformer 2 with a primary winding 4 in series with a transistor 1, a secondary winding 6 supplying the load via a rectifier 3 and a transistor 12 for turning off the transistor 1, the base of transistor 12 receiving signals from current sensing resistors 5,8 respectively located in the primary circuit of the transformer 2 and in the load circuit. The mean load current is thereby maintained approximately constant with variation in the input voltage to the converter, eg. for inputs in the range of about 100 to 250 V. A motor 21 may be energised by the accumulator 7, or the converter may simultaneously supply the accumulator 7 and the motor 21, current sensing resistors 8,23 then determining the magnitude of the constant charging current and constant motor current. A network 9,10,11 provides feedback from the secondary 6 to the base of transistor 1. Where a low voltage accumulator 7 is used, the network 9,10,11 may alternatively be connected to an additional secondary (24), (Fig. 2), of transformer 2. <IMAGE>

Title: An inductor
Inventor: MOLYNEUX-BERRY ROBERT BEWES
IPC: H01F30/08
Filed: 1984-11-26
Abstract: An inductor is formed by four coils 9A, 9B, 9C and 9D arranged alongside each other and connected in parallel, adjacent coils being wound in opposite directions. The coils are supported against electromotive forces tending to pull them together by insulating strips 10. The coils are enclosed within an electromagnetic shield formed by a conductive cabinet 1. Because of the arrangement of the coils the magnetic field generated by them is confined to a region in the close vicinity of the coils and this reduces to a minimum losses which would otherwise occur as a result of the proximity of the shield. <IMAGE>
