Title: Warning alarm for mining machinery
Inventor: RAWLINS GRAHAM CLENTON
IPC: G08B21/00
Filed: 1983-01-07
Abstract: An advance warning alarm for indicating that a machine used underground in mines is about to operate, has an impeller (16) in a housing (10). The machine uses water as its operating medium and the impeller (16) is rotated by the water prior to the machine. When the impeller (16) is rotated by the water flow a cam (20) in its shaft (18) operates a piston (26) in a cylinder (28). Movement of the piston (26) co- operates with a control valve (34) to operate a device (40) and produce an audible alarm. <IMAGE>

Title: Ratchet
Inventor: MARSHALL DAVID WILLIAM
IPC: B25B23/142
Filed: 1983-01-19
Abstract: In order to provide a ratchet which can be made from inexpensive parts, it comprises a pair of discs (5 and 6) having ramps (5a, 6a) upset from a peripheral zone of the discs and terminating in shoulders (5b, 6b). The discs are loaded together by a spring 9 which enables the drive to be transmitted via the faces of the ramps (5 and 6) up to a predetermined limit before the discs separate and the ratchet clicks over. In the opposite direction the drive is transmitted through the shoulders (5b, 6b), which may then be inclined to provide a torque limitation. The ratchet may for example be used in wheel braces or in spark plug spanners. <IMAGE>

Title: Boiler
Inventor: BAINBRIDGE ALAN
IPC: F22B31/04
Filed: 1983-02-18
Abstract: A boiler capable of producing saturated steam or superheated steam at a low or at a high pressure comprises main (10) and a secondary (22) furnace of which at least the latter is controllable to the extent that it may raise or lower the temperature of gases discharged from the main furnace section (10), prior to passage past a stack of superheaters (24).

Title: Continuous silicon carbide whisker production
Inventor: BEATTY RONALD L
IPC: C01B31/36
Filed: 1982-12-14
Abstract: Methods and apparatuses for obtaining silicon carbide whiskers on a continuous basis. Coked rice hulls or other carbon - and silicon bearing feed materials are continuously fed to a heating zone (18) in an unagitated state in order to promote whisker growth. The heating zone is continuously purged with an inert gas (22a), such as nitrogen or argon. The inert gas carries away gaseous impurities through vents (25) which are located directly in the heating zone, and prevents oxidation of the whiskers. The feed materials are dried in a dehydrating furnace (14) and are fed in a dry state therefrom to the heating zone in order to prevent erosion of the furnace walls.

Title: Improvements relating to flashlights
Inventor: DALTON DAVID RICHARD
IPC: F21L4/04
Filed: 1984-04-27
Abstract: A flashlight comprising a body for housing one or more dry cells, a bulb holder 13, a head portion 11 detachably mounted on the forward end of the body and surrounding the bulb holder 13. The head portion 11 is capable, when detached, of receiving the rear end portion 10c of the body so as to form a base for supporting the body and bulb holder in an upright position. The head portion 11 includes a reflector and may be connected to the body by means such as co-operating threads 14 on the head portion 11 and the body. A rotational movement of the head portion 11 relative to the body about the lengthwise axis of the body, may therefore adjust the axial position of the head portion 11, and thus the reflector, relative to a bulb 12 mounted in the bulb holder 13 so as to adjust the shape of the beam produced. <IMAGE>

Title: Metal hose clip
Inventor: MCCABLE ALBERT GEORGE
IPC: F16L33/08
Filed: 1984-06-15
Abstract: A hose clip is provided in three separate parts: a screw 16, a housing 11 arranged so that the screw can fit completely within it, and a strip 13 of reasonably soft material, which may be cut off to length from a roll to suit the size of hose to be coupled. An indent is formed in an end of the strip for engagement with an abutment on the housing. The screw may be provided with a buttress thread so that it can form its own "thread" in the strip. Instead of a multitude of different-sized hose clips, all that is required to provide hoseclips in a workshop is a single supply of screws, a single supply of housings, and a roll of strip that can be cut to a length suitable for passing around the particular hose, and indented as required. <IMAGE>

Abstract: A fluid valve arrangement (20) includes a valving element (30) in the form of a freely slidable poppet (22), a freely slidable pilot piston (40) having an elongated integral pin (44) extending axially toward the poppet (22), but unconnected thereto, and an integral elongated spear (52) with a frusto-conical portion (50), extending axially in the opposite direction. The amount of opening of the valve 20 is determined by the position of throttle 80. In a spool valve, Fig. 2, not shown, the spool is the valving element and has the above elements at each opposite end of the spool, namely a pilot piston with an integral pin unconnected to the spool at the inner end of the pilot piston and an integral spear, with a frusto-conical portion at the outer end of the pilot piston. <IMAGE>

Title: Method of measuring depth of skin wrinkles and device therefor
Inventor: ABE TAKEHIKO
IPC: A61B5/107
Filed: 1984-09-18
Abstract: The method utilizes a video camera 1 which magnifies the skin surface by 10-100 times and is connected to a tape recorder 6 and a monitor T.V. 7. The magnified video signal is then dual-valued by a video pattern sensor 9 and projected on to a monitor TV set (8). A manual control device (10) for establishing luminosity values is then operated to measure the difference between the value on an indicator (11) when the darkest part on the monitor TV picture (8) becomes white and the value on the indicator (11) when the lightest part becomes dark (difference in luminosity). By multiplying the difference in luminosity with the conversion factor of the difference in luminosity and depth, the depth of wrinkles can be calculated. <IMAGE>

Title: A device for automatically finding a required point of a magnetic tape in a video recorder and/or audio tape recorder
Inventor: ZIMMERMAN HORST
IPC: G11B15/00
Filed: 1985-02-21
Abstract: Automatic forward or backward winding of a cassette tape and to a point determined by a selected elapsed time entered by keyboard (1), is effected. A subtractor (8) coupled to the outputs of a tape length counter (6) and a tape remainder counter (7) provides an output indicating the elapsed playing time corresponding to the wound state of any given inserted tape cassette. A store (2) coupled to the output of the keyboard (1) has an output coupled to one input of a comparator (9), the other input of which is coupled to the output of the subtractor (8). Signals from corresponding outputs of the comparator (9) are utilised to provide, in response to a starting signal from a switch (3), signals controlling the forward or backward winding, and stopping of the tape. A comparator (14) having inputs connected to the tape length counter (6) and the keyboard (1) is arranged to inhibit actuation of the logic circuit via switch (3), when the elapsed time entered via the keyboard (1) is greater than the available playing time of an inserted tape cassette. A warning indicator (18) provides a corresponding signal. <IMAGE>

Title: Carton for liquid
Inventor: HILL MERVYN BEVERLEY
IPC: B65D5/74
Filed: 1985-05-13
Abstract: A carton 1 for containing a liquid such as milk or fruit juice comprises means for defining two spaced orifices 2 and 3 for providing a controlled flow of liquid from the container. The container 1 is formed from a blank which, when assembled to form the container, provides two folded back arrangements which when pulled out form the orifices 2 and 3 when a part of the container is cut or torn off along oblique cut or tear lines indicated on the exterior of the container, which also carries instructions for the user. When the container is tilted to dispense the liquid contents, a steady controlled flow of liquid is achieved from dispensing orifice 2 which can be targeted at the desired target area, without "overshooting", slopping or spilling. <IMAGE>

Title: Wrap spun yarns
Inventor: HUNT ROBERT JOHN
IPC: D02G3/28
Filed: 1986-03-19
Abstract: A yarn having the advantages of a wrap-spun yarn but considerably enhanced appearance is formed from two separate wrap spun yarns which are first wrap spun with opposite directions and different numbers of wraps per metre. The resultant yarns, which may be wound side by side on a common package, are then twisted together in the direction that the lesser wrapped yarn is wrapped, e.g. by using the common package as the supply source in a conventional two-for-one twister or ring twister. Over a wide range of twist, it is found possible to obtain a resultant balanced yarn.
