Patent GB-2016940-A (GB)
Title: Emulsion generator
IPC: B01F5/04
Filed: 1979-03-14
Abstract: The narrower end of a frusto-conical chamber 2 is divided by a circular wall into a central aperture and an annular aperture for communication with two sources of liquids to be emulsified. The flow of the liquids is accelerated through the aperture 4 in order to reduce their pressure to the vapour pressure of one of the liquids to be emulsified, thereby creating a cavitation zone, followed by a progressive increase of the pressure along the chamber 2, until the atmospheric pressure is reached. <IMAGE>
Patent GB-2045731-A (GB)
Title: Closure application machine
IPC: B67B3/20
Filed: 1979-04-03
Abstract: In order to ensure that closure caps 1 are placed squarely onto the necks of containers 8 without hooking under threads 8b, there is provided a placement claw 10a in continuation of a closure feed track 2, 3a and 3b. As closure 1 passes along the feed track, it engages plate 10 carrying placement claw 10a so as to lift the latter into alignment with the terminal horizontal portion of the track 3b. The closure 1 is thus fed into and maintained horizontally by the placement claw 10a. As the trailing end of the closure 1 leaves the feed track, the placement claw drops, while maintaining the closure 1 substantially horizontal, until the cap is supported by the threads 8b. The container, with applied closure 1, then passes to a pre-tightening device 15, 16. <IMAGE>

Title: Disc record preform and method of making a disc therefrom
IPC: B29B11/14
Filed: 1980-04-11
Abstract: A preform 10 for use in making a video recorded disc comprises a body of plastics material having substantially flat top 12 and bottom 14 surfaces and a peripheral surface 16 extending between the top and bottom surfaces. The peripheral surface includes a first portion 18 intermediate the top and bottom surfaces and of a peripheral size greater than that of the top and bottom surfaces. Second 20 and third 22 portions extend from the first portion to the top and bottom surface, respectively. Each of the second and third portions has a dimension which decreases from that of the first portion to that of the top or bottom surface so that the surface of each of the second and third portions is angled away, e.g. angle D, from the top and bottom surfaces, respectively. When the preform is engaged by the molds in a record making press 30 the angled surfaces of the second and third portions serve to minimize if not eliminate the trapping of air and gasses along the surface of the record being formed which cause defects in the record surface. <IMAGE>

Patent GB-2078184-A (GB)
Title: Driven roller conveyor
IPC: B65G47/26
Filed: 1981-05-11
Abstract: In driven roller conveyors it is necessary to enable the drive to slip when an accumulation takes place. This has conventionally involved both noise and wear. In accordance with the invention the drive from a longitudinal drive shaft 3 is passed to a roller 2 by means of a driven wheel, preferably a bevel gear 4a, engaging a contact surface, preferably an annular gear 5a, of a driven wheel 5b in driving contact with the roller 2. The contact surface 5a is provided with one or more gaps 6a which enable the drive transmission to be regularly interrupted and restored, so that on accumulation, the transmission only needs to slip until the gap 6a reaches the wheel 4a where the drive wheel 5b will stop. <IMAGE>

Title: Electrical signal generation
Inventor: ARTHUR JOHN WILLINS
IPC: H03B23/00
Filed: 1982-03-02
Abstract: For digitally generating a chirp signal. a ROM 5 stores digital numbers representing successive values of the chirp, and a counter 8 is driven by pulses derived from a timing and clock unit 6 so as to cause the ROM 5 to output the digital numbers in turn. A digital to analogue converter 12 converts the signals into an analogue output which is mixed with a Carrier signal derived from a local oscillator 18.

IPC: B23Q9/00
Filed: 1982-03-23
Abstract: A pair of spaced apart flanges 3, 4 mounted on a chain saw fit snugly over a guide bar 2 which is attached to the work. When the operator forces the cutter bar 27 of the saw into the work by raising the handle 14 of the saw, the reaction may be absorbed by the lower teeth of the chain saw claw 12 or by a pwal and rack device 16, 17. The chain saw may be attached to a carriage, which is constrained to run along a guide bar of various sections. The carriage holds the chain saw at the correct cutting angle as it is winched along the guide bar, thus relieving the operator of the necessity for holding the saw. <IMAGE>
