Title: Improvements in or relating to drafting machine heads
IPC: B43L13/08
Filed: 1981-02-02
Abstract: A drafting machine head is provided with a rotatable drawing ruler carrier whose angular position on a graduated circle is incrementally detected by means of scanning elements and is converted into displayable angular valves by an up/down counter, and with one or several electronic data stores, characterised in that it contains an electrically actuable locking unit (10, 11) for the rotary movement of the drawing ruler carrier (13), which unit is active in any angular position and is connected through an electronic comparator (25) to the data store or stores (23) in such a way that the values detected on the graduated circle (12) and the values contained in the data store (23) trigger the locking unit if they are in coincidence. By this means a drafting machine head is provided which can be set to a higher degree of accuracy and is less subject to wear than is known from the prior art. <IMAGE>

Title: Fluid Conducting Spigot and Socket Connector Assembly
IPC: F16L37/14
Filed: 1981-04-14
Abstract: As assembly for connecting together fluid-connecting spigot (5) and socket (1) members employs a U- shaped locking clip (11) with parallel legs (12) sliding in chordwise passages (9) of the socket member. The spigot member has an external groove (8) which is engaged by the legs of the locking clip when the spigot is inserted into the socket and the clip is slid into its operational position. The clip can be retained in this position by the "snap" engagement of the base (13) of the U with a transverse groove (14) in the face of the socket member. The assembly is particularly useful for connecting a demand valve (3) into the facemask of a breathing apparatus. <IMAGE>

Title: Track vehicles
IPC: B60T7/12
Filed: 1981-05-14
Abstract: An underground track vehicle has an hydraulic circuit including a pump (20) driven in accordance with speed of movement of the vehicle along the track, and a piston and cylinder assembly (22, 24) controlling movement of pivotally mounted fork members (26, 28) engageable into the ground when moved to an operable position so as to retard the vehicle when movement of the vehicle exceeds a predetermined speed. A valve (32) (see Figure 4) controls the flow of fluid to the assembly (22, 24) and return of the members (26, 28) to a non-operable position is controlled by a changeover valve (64) in the hydraulic circuit.

Title: Injection moulding
Inventor: HENDRY JAMES WATSON
IPC: B29K105/04
Filed: 1983-05-11
Abstract: A process of producing an injection moulding of plastics material comprises introducing the plastics material in the form of a molten stream into a mould space, and at one or more selected positions injecting a predetermined, finite quantity of a non-plastics fluid under pressure into the stream of plastics material at a controlled rate, the fluid being injected through means (19;90) around which flows the stream of plactics material whereby the fluid is injected directly into the plastics material, the fluid thereafter flowing simultaneously with the plastics material between the mould surfaces to fill the mould space (12) and exerting a pneumatic pressure on the surrounding plastics material (8) to pressurise the plastics material outwardly towards the mould surfaces. 
<??>The invention further provides an apparatus for producing an injection moulding in accordance with the process, and an injection moulding produced thereby.

Patent GB-2182456-A (GB)
Title: Display systems
Inventor: BANBURY JOHN RANDOLPH
IPC: G02B27/01
Filed: 1983-09-13
Abstract: In a head-up display system light from an object (14) is deflected on to a collimator (16) and superimposed on an external view through a combiner (10) from an observing position (11). Relay optics (17) in the path of light from the object (14) has spaced apart elements (L1, L2) which produces first and second exit pupils (P1, P2). Exit pupil volumes (V1, V2) overlap to give an extended field of binocular view. In a further arrangement (Fig. 3, not shown), light from a head down display is reflected by mirrors (39,40) to cross the optical axis of the head-up display between the lenses (L1, L2) of the relay optics. <IMAGE>

Patent GB-2133503-A (GB)
Title: Valve
Inventor: ZETTIER KARL-HEINZ
IPC: F16K17/02
Filed: 1983-12-02
Abstract: The cream discharge of a centrifuge for skimming milk is adjusted to the desired concentration value by means of a valve 1 having a variable throttle cross-section which is set to a minimum by an adjusting screw 3. An axially movable valve member 4 is subject to product action in chamber 17 and compressed air action in chamber 12, the pressure in chamber 12 being initially set to that in product chamber 17, which can be read off monometer 18. If the pressure on the product side increases, the valve member 4 is displaced towards the compressed air side, so that the throttle cross-section 7 is increased and the pressure is again reduced. This prevents inadmissibly high cream concentration. In the case of a partial or complete emptying of the centrifuge, a piston 5 is pressed by compressed air against a conical shoulder 13 of valve member 4 and holds it in position until the end of the emptying process so that the correct setting is immediately obtained when separation recommences. <IMAGE>

Title: Axle suspension for a vehicle
Inventor: FUCHS DIETRICH
IPC: B60G9/02
Filed: 1984-05-16
Abstract: The suspension, particularly at the rear of a bus, has a so-called open-A axle suspension frame having two arms (4). Straight portions of the arms (4) are formed by closed hollow portions having an evenly continuous contour such that no stress sources occur. The two arms (4) thus each form a flexural torsional beam. Inasmuch as the two arms (4) can independently absorb the forces transferred to them, they are preferably designed as a split arrangement. A transverse link, preferably in the form of a wishbone (8) is arranged between the rear axle (1) and the chassis frame independently of the arms (4). The outer end of each arm (4) has a support (5) for an air spring and a shock absorber. <IMAGE>

Title: Infra-red intrusion detector
Inventor: SCHOFIELD ROY ALAN
IPC: G08B29/04
Filed: 1984-06-04
Abstract: To monitor that an infra-red radiation detector element 22 within a housing 10 has not been disarmed, for instance by rendering opaque to infra-red an infra-red transparent element 16 masking a window 12 in the housing 10, through which infra-red radiation 26 from an intruder enters and is focussed by an optical system 18 onto the element 22, an infra-red radiation generator 32 comprising for example a low-temperature lamp 34 is mounted externally of the housing 10 so that element 22 receives radiation therefrom and provides a signal to a processor 30. The latter will provide an alarm in the event of absence of radiation reaching the element 22 from the generator 32 and/or change in the radiation reaching the element 22 commensurate with the approach of the intruder. <IMAGE>
