Title: A dental apparatus with a number of dental instruments connected to a common control circuit and a common operator unit
Inventor: HENRICHSEN FRANK
IPC: A61C1/00
Filed: 1981-06-12
Granted: 1984-07-19
Abstract: In a dental apparatus, in which a number of instruments (19 to 22) are connected to a common control circuit (23) which is further connected with a common operator unit (17) having a control member, which is planar movable out of a home position, auxiliary functions related to the instrument operation such as control of coolant composition and energization of an air blow may be energized by the means of the common operator unit (17) by actuating the control member thereof with a movement different from the instrument energizing movement. The energizing movement for an auxiliary function may have another direction than the instrument energizing movement, for example perpendicular thereto in the home position of the control member. In an embodiment in which a certain minimum duration is prescribed for the instrument energizing movement an auxiliary function may be carried out by a movement of shorter duration. The two possibilites may be combined so that also in case of a different direction related to the instrument energizing movement a discrimination may be made between actuation of auxiliary functions of a shorter or longer duration for the purpose for example of stepwise conrol of an auxiliary function.
Patent DE-3165280-D1 (DE)
Title: Cheese basin for the production of hard cheese
Inventor: QUILLIOU GUY
IPC: A01J25/15
Filed: 1981-11-24
Granted: 1984-09-06
Abstract: A cheese making apparatus comprises a rectangular vat, a pressing plate, a filtering sheet supported on the bottom wall of the vat for displacement in a longitudinal direction, and a transverse partition affixed to an end of the filter sheet adjacent a fixed end wall of the vat for simultaneous displacement with the filtering sheet in this direction. The partition defines with the side walls, the bottom wall and a mobile end wall opposite the fixed end wall an operating volume of the vat determining the amount of curds to be held in the vat for producing cheese from a pressed mass of the curds wherefrom the whey has been drained. Displacement of the partition changes the operating volume and the transverse partition is elastically compressible in a vertical direction whereby lowering of the pressing plate into the vat compresses the partition and permits the plate to apply pressure to the curds held in the vat.

Inventor: WALTERS ROBERT ERNEST
IPC: H04Q11/04
Filed: 1982-01-27
Granted: 1985-07-11
Abstract: A technique for transmitting data with digitally encoded speech samples involves replacing at least two of the least significant bits of each speech sample so that one of the bits is representative of the data to be transmitted and another is a control bit. The technique can be implemented using an interface circuit which includes a codec 61 for producing digitally encoded speech samples. Data signals from a data terminal are stored in shift register 72 and inserted bit by bit into the bit 7 position of each sample by circuit 68. A control bit is inserted into the bit 8 position using circuit 69. Data in incoming speech samples is sensed by circuits 84, 85, 86.

Title: Free piston internal-combustion engine with an independently driven cam
Inventor: ALLAIS EGIDIO
IPC: F02B71/04
Filed: 1982-10-18
Granted: 1985-10-31
Abstract: The engine comprises one or more units having a pair of pistons on a common shaft connecting two opposed cylinders and driving the permanent-magnet moving part of a linear alternator. The shaft carries two robust pegs engaging the rim of a cam driven by an independent eccentric motor. The cam rotates substantially in synchronism with the engine so that the pegs are in virtual contact with it and no energy loss is implied. The contact becomes positive if the piston rod overruns or if one cylinder misfiring fails to initiate compression in the other. The engine can be started by means of the independent motor without recourse to compressed air or use of the linear alternator as a starter motor.

Title: Re-enterable closure
Inventor: TIGHT TIM DEXTER
IPC: B29C61/02
Filed: 1982-06-15
Granted: 1987-01-15
Abstract: A recoverable wrap-around sleeve 4 secured by rails and channel 1,2 and which is used to seal a substrate can be re-entered and re-sealed in the following way. A central section of the sleeve is removed, after cutting away the rails and channel, leaving butts of the sleeve on the substrate. A new sleeve is then recovered across the butts of the old sleeve. If the new sleeve is to seal properly there should be no leak path between the old butts and the new sleeve. In order to avoid such a leak path, any gap between the remnants of the old rails must be filled with adhesive. This is achieved by providing means, such as deformations 7, at the base of one of the rails 1 or on a flap 3 adjacent one of the rails 1 which allows flow of adhesive 8 between the rails when the original sleeve 4 is installed.
