Patent GB-2132751-A (GB)
Title: Ambient light control for artificial lighting
Inventor: PROUD GRAHAM BERNARD
IPC: H05B41/392
Filed: 1982-12-23
Abstract: An ambient-light operated On/Off control unit for a fluorescent lighting load 1 is mains operated and includes a zero-crossing, pulse-triggered triac 16 for controlling power supply to the lighting load. The ambient-light sensor is a photo-transistor 5 having a wide acceptance angle and an optical response which peaks in the infra-red region, the sensor feeding into an operational amplifier 9 with an hysteresis operating cycle, to avoid establishing a hunting condition when the lighting load is switched On. A capacitor 10 provides the ambient-light sensor circuit with a long time-response, to avoid operation due to transient ambient-light changes, and also provides a short lighting-load operating period when the control unit is initially powered to test the fluorescent starter units. At other times when the control unit is powered and the lighting load is not, a LED indicator 25 shows the "power-on" condition. <IMAGE>

Title: Emitters for emitting earth radiation
Inventor: SCHMIDT PAUL
IPC: G21G4/00
Filed: 1983-02-14
Abstract: An earth radiation emitter, especially for treating living organisms, plants and foodstuffs, comprises a housing 17 containing two sets of parallel conductor rods 22, 23. The rods 22 are held at one end in an insulating holder 20 which is fixed in the housing and the rods 23 are similarly held in a holder 21 which is pivoted on a vertical pivot pin 24. The rods 23 can thus be moved by a handle 25 against the action of a spring 26 between a position in which each rod 23 is parallel to and directly above one of the rods 22 and an angularly offset position as shown. When the emitter is set in a field of earth radiation, this radiation is concentrated and emitted from the free ends of the rods 22, 23 which are directed at the organism, plant or foodstuff to be treated. The strength of the radiation and its efficiency can be set to an optimum by setting the angle between the two sets of rods. The irradiation can have beneficial effects on illness in human beings and animals and on the growth of plants. <IMAGE>

Title: Process and apparatus for producing a fluted operative surface of a cam
Inventor: VOGLINO BERNARDO
IPC: B24B19/12
Filed: 1983-05-04
Abstract: A process for producing a fluted surface extending around a straight longitudinal axis and serving as the operative surface of a cam 3 comprises providing a grindstone 1 which rotates around an axis and has a cylindrical working surface, placing such surface in contact with the fluted surface 4 of the cam blank, rotating the cam 3 around its axis Y, imparting thereto an angular oscillatory motion around an oscillation axis V of fixed direction, imparting to the grindstone a displacement adapted to move the grindstone working surface in a rectilinear direction F, and also impart- to the axis of the cam a second angular oscillatory motion about a second oscillation axis Z and a second displacement of the grindstone in a predetermined rectilinear direction G. Control means link the angular oscillatory motions of the cam and the displacements of the grindstone, so that, in all the operative positions of the cam, that segment 5, 6 of its fluted surface 4 which is in contact with the grindstone working surface is disposed parallel to the grindstone axis. <IMAGE>
Patent GB-2120557-A (GB)
Title: Grip and method of making it
Inventor: ALDRIDGE JAMES STEWART
IPC: A63B53/14
Filed: 1983-05-23
Abstract: A moulded grip for a handle of a sports implement or tool when mounted on the handle has a conventional appearance with its outer surface having protrusions simulating that of a grip formed by winding a strip onto the handle (Fig. 2c). However the grip when moulded (Fig. 2a), has a substantially plain outer surface; protrusions (8) or the like are moulded in its inner surface. When the grip is mounted on a substantially plain handle, since it is of flexible material it distorts due to the presence of the protrusions on the inner surface and these become apparent on the outer surface (10, Fig. 2c). <IMAGE>

Patent GB-2129247-A (GB)
Title: Signal sampling circuit
Inventor: FILLIMAN PAUL DEAN
IPC: H04N9/72
Filed: 1983-10-13
Abstract: A signal clamping and sampling circuit wherein signals to be sampled are applied to a voltage amplifier (52). The output of the voltage amplifier is coupled in common to the inputs of first (53) and second (57) matched operational transconductance amplifiers (OTA's). During an initial clamping reference interval, the first (53) OTA conducts to form a feedback clamping network for establishing input and output reference bias conditions for the voltage amplifier. The second (57) OTA conducts during a subsequent sampling interval for processing signals to be sampled. The output reference bias of the voltage amplifier determines substantially identical input bias conditions for both the first and second OTA's, thereby significantly reducing the likelihood of signal processing offset errors being produced as between the clamping and sampling intervals when the first and second OTA's are respectively conductive. A level shifting network may be used for applying the signals to the voltage amplifier for providing signals compatible with the input requirements of the amplifier. <IMAGE>

Title: Hydraulic control system
Inventor: SCHWERIN GUNTHER
IPC: F15B13/02
Filed: 1984-07-23
Abstract: A hydraulic control system (10) for controlling a lifting mechanism on an agricultural vehicle has a proportionally acting directional control valve (11). A throttle valve (13) has a throttle slide (18) with two control chamfers (31, 29) influencing the connections from the inlet space (23) to the adjacent spaces (22, 24) and in a pressure space (21) located opposite a spring space (25) receiving the spring (26) is subjected to the pressure in the outlet space (24). When the directional control valve (11) and the following directional valve (77) operate in parallel, with pressure conditions different from one another, the throttle slide (18) always keeps constant the pressure gradient effective on the control slide (37) and the pressure gradient available for the control stream to release the shut-off unit (15), so that the proportional action of the directional control valve (11) is maintained even when there are higher load pressures on the second hydraulic motor (79). <IMAGE>

Title: Improvements in or relating to chain and sprocket gearing
IPC: A24B7/14
Filed: 1946-01-10
Abstract: 588,981. Chain gearing. DEARSLEY, G., and MOLINS MACHINE CO., Ltd. Jan. 10, 1946. No. 847/45. [Class 80 (i)] [Also in Group XXX] To reduce wear and extend life in chainconveyer gearing, particularly for feeding tobacco in a tobacco-cutting machine as described in Specification 365,997, [Group I], the driving contact between the chain and sprocket-teeth is restricted to the last tooth on the leaving side of the chain by making the pitch of the chain and sprocket-teeth dissimilar, the former being the lesser when the sprocket drives the chain and the larger when the chain drives the sprocket, the tooth-gaps 7 in the sprocket 1 being wide enough circumferentially to prevent face-contact with the chain-teeth 6 at other points, whereby the tendency of the chain to climb the sprocketteeth as wear occurs is avoided for a long period and in addition the chain is supported tangentially against the pressure of the conveyed material adjacent both entry and leaving sides by plates 30, which fit into axially-spaced circumferential grooves in the sprocket. Arcuate sprocket tooth-crests 8 support the complementary chain-links 9 radially on the sprocket and the tooth-gaps 7 have arcuate sides joined by a flat base. Specifications 4303/97, [Class 80]; 244,087, [Class 80 (i)], and 546,434 also are referred to.

Title: Knife
Inventor: DAVIS ROGER IAN
IPC: B26B1/08
Filed: 1986-07-08
Abstract: A knife of the kind having a blade (14, 43) and a handle has an extendible and retractable blade edge guard (16, 45). When the blade (14, 43) is extended, any violent movement of the knife with the cutting edge in a leading attitude acts inertially to disengage a detent (27, 55) from a recess (28, 57) in the guard (16, 45) so that a tension spring (17, 46) quickly extends the guard (16, 45) into its projecting, operative position to guard the blade edge (21, 50) and prevent at least serious injury. When the blade carrier (13, 42) is fully retracted, its engagement with a part (31, 58) of the guard (16, 45) causes that also to retract and be engaged again by the detent (27, 55) due to spring-bias.
