Title: Sequential ignition and extinction for gas burners - uses circuit with sawtooth versus variable threshold comparison to operate gas valve and spark ignition for safe low temp. cooking
IPC: F23N5/20
Filed: 1980-11-28
Abstract: The system uses alternate flame on/flame off periods in which the gas supply is automatically turned on or off with automatic spark ignition. A rectified supply drives a ramp generator which, in conjunction with a voltage comparator generates a saw tooth voltage wave form at an input of a second comparator where the sawtooth is compared against a DC threshold level set by the operator. When the sawtooth crosses the threshold a thyristor circuit operates a valve to supply gas to the burner, the gas being ignited by a spark plug. The spark generator is triggered by the same signal as operates the gas valve. When the sawtooth waveform returns across the threshold the gas is turned off. The relative ON/OFF times are determined by the threshold level in relation to the sawtooth waveform.

Inventor: SCHMIDT MANFRED
IPC: A61C1/00
Filed: 1981-05-14
Abstract: In order to control dental instruments, including a multi-function syringe, in conjunction with a dental treatment apparatus whose instruments can be controlled using a foot control element and whose syringe handpiece does not contain any valves for its working media, a device is proposed with which both a foot control of all instruments including the syringe handpiece can be carried out using the foot control element, as well as a hand control of the syringe handpiece using a manually activated function selection and signal transmission unit accommodated in the syringe handpiece. The alternative foot control and hand control of a multi-function syringe without valves for its working media in conjunction with the foot control of the further instruments is improved to the extent that the hand control of the multi-function syringe can be guided exclusively on the syringe handpiece.

Title: Power cable involving both polyethylene and rubber insulation - using ground copper strip as an intermediate metal layer requiring radial flexibility
Inventor: CHAMPOMIER RENE
IPC: H01B7/22
Filed: 1981-10-02
Abstract: In the construction of an electric power transmission cable for medium voltage distribution (up to 60 kV), a metal (copper) screen, located a paper cover on a multistrand core cable having crosslinked polyethylene (XPE) insulation between extruded semi-conductor screen layers, is made of strip material previously impressed with transverse grooves and laid up helically to a short pitch. The grooved metal strip is overlaid with a helically wound textile tape and further layers of insulating rubber with an interlayer of steel braiding. The grooves in the metal layer increase its radical elasticity to compensate for the relatively high coefficient of thermal expansion of the crosslinked polyethylene layer, allowing heat cured rubber external insulation to be used on lay-ups involving both metal and (XPE) layers. The short radial pitch also improves the longitudinal flexibility of the composite cable.

Title: Mobile index for slide caliper, gauge etc. - has complementary mobile index for sliding base to permit retention of scale when used in places of difficult access
IPC: G01B3/00
Filed: 1981-10-16
Abstract: The mobile index is mounted on a slide caliper or a similar measuring gauge in order to be able to take measurement in places of difficult access. The index is such that it is moved by the slide when taking a measurement. The graduations on this index then coincide with the graduations on the slide. When the slide is moved back, in order to remove the caliper from the measurement place, the index stays in place so that the operator can still read the value of the parameter. The operator can take with a high accuracy a measurement in a place whose access is difficult, then remove the caliper and read the measurement without the relative spacings being disturbed.

Patent FR-2498936-A1 (FR)
Inventor: LEICHTFRIED FRIEDRICH
IPC: A63C7/10
Filed: 1982-01-29
Abstract: The invention relates to a ski brake in which the brake arms are mounted in a pedal, which can be pivoted counter to spring force, so as to be adjustable in such a way that they can be retracted into a position of readiness above the ski surface. Such a ski brake is to be constructed by the invention in a particularly simple manner and of few parts. This is achieved according to the invention in that two wire springs forming the pivot axis of the pedal are accommodated in the pedal, each having a limb which projects from the pedal parallel to the longitudinal centre plane of the ski and on which the brake arm is eccentrically mounted via a holding body. The retraction of the brake arm takes place by means of stops which are arranged on the ski surface at such a point that they pivot the respective holder inwards when the pedal is pressed down.

Title: Cooking meat esp. ham in plastics mould serving as package - and having cover pocket which is cut off after collecting meat juice
IPC: B65D81/34
Filed: 1982-04-23
Abstract: Cooking meat esp. ham in plastics containers which serve both as mould and packaging for the cooked prod. is described, the meat being vacuum-packed prior to cooking. The plastics container has an all-round, external flange at the top. A heat resistant, food quality plastic sheet is seamed to a first edge flange of the container. The sheet is longer than the distance between the first edge flange and the second, opposite edge flange. The plastics sheet is folded up and over, upon itself and the free edge of the sheet is seamed to the second edge flange of the container. The open edges of the folded sheet are seamed together and an intermittent seam made between the sheet and the first edge flange. This leaves a pocket overhanging the first edge flange and in communication with the container space via channels through the intermittent seam of sheet to first edge flange. During cooking, juice exuded by the meat is expelled from the container into the pocket. After cooling, the intermittent seam is made complete and the pocket of juice is sheared off. The juice exuded by the meat during cooking is removed from the meat to improve its quality and value. This is achieved without handling the prod. or opening the seal on the container which is always accompanied by risk of prod. contamination.

Abstract: The winding roller (1) for strip material has one or more flats (2) machined on it, so that fittings can be attached for securing the end of the strip at the start of a winding operation. Flats can be equally spaced around the periphery and can also be spaced along the periphery along a line parallel to its axis of rotation, for a distance equal to the width of the strip. Incorporated in the fittings are small dia. rollers (4) supported so that they do not extend beyond the dia. of winding roller. The ends of the small rollers can be retained by shaped blocks (3) attached to the flats, or by members shaped as frames, holding the rollers in position. A wide range of alternative devices to retain the rollers include magnets, spring loaded locking elements and other fittings.
