Patent DE-2539774-A1 (DE)
Title: Synchronizing quartz oscillator of clock - by determining phase differences used to adjust system
Inventor: HUMMEL HERBERT
IPC: G04C11/08
Filed: 1975-09-06
Abstract: A quartz oscillator of a clock regulating system, in which the frequency of the system is influenced by pulse rates or clock pulses derived from the oscillations of a quartz crystal is scynchronised by taking an effective signal from the oscillating system and determining, by phase comparison with the derived quartz pulses, the frequency deviations of the effective signal. The frequency of the oscillating system is then modified as a function of these frequency deviations.

Title: Holding method for signal plate in fused cartridge - involves signal plate which is ejectable, and held in cartridge central recess
Inventor: ANDERSSON PER ULF
IPC: H01H85/30
Filed: 1975-12-19
Abstract: The signal plate (6) is subjected to pressure by a leaf spring (7) and it is held in position by projecting elements (9), when the leaf spring (7) is held by a signal wire; the elements (9) project beyond the signal plate (6), and release it when the leaf spring is freed by melting of the signal wire (5) so that it is thrown out by the spring. The system is used to signal when a fuse has blown; the signal wire is connected in parallel with the fuse, so that after the fuse wire has melted, the entire current in the circuit flows through the signal wire which then rapidly melts.

Title: Electrically neutral or acid-resistant housing with lid - made by deep-drawing plastics-coated metal sheet
Inventor: KLASCHKA PETER
IPC: B65D25/14
Filed: 1975-12-19
Abstract: An electrically neutral and/or acid-resistant housing is in the form of a metal cup or container with an insulating or protective coating on both sides, and furnished with a closure lid. Both the container and its lid are produced by deep-drawing from metal plate laminated on both sides with the protective coating material. Pref. an aluminium plate with a plastics laminated coating on both sides is used. A rim or beading of conventional type may be used for fitting the lid onto the container. To produce an airtight seal, the two components may be welded together at their junction, esp. by H. F. seal welding. Grooves or other points of intentional weakness may be incorporated to ensure rupture at a predetermined place if internal excess pressure occurs. A silicone rubber sleeve may be introduced between the lid and the vessel. Used for acid-resistant containers, for foodstuffs containers or for electrically insulated housings and vessels. By comparison with previous practice, the lid as well as the vessel itself is simply manufactured from metal, esp. aluminium sheet coated on both sides with plastic material. This results in economic manufacture for mass prodn.

Title: Regenerating adsorber from effluent treatment - in multistage fluidised bed with decreasing gas speeds in successive stages
Inventor: GAPPA GUENTHER ING GRAD
IPC: B01J8/36
Filed: 1976-01-22
Abstract: Parent patent describes a method of operating a fluidised bed reactor for the thermal regeneration of activated carbon charged with constituents adsorbed during the purification of waste water. In the addn., the same reactor is used, but for the regeneration of inorganic adsorption agents. In the addn., the reactor is operated in each individual section of the fluidised bed with a fluidising gas speed which increases gradually from the adsorption agent outlet towards the adsorption agent inlet, and which is 1.2-3.0 (1.5-2.0) times the gas speed at a lift point for the fluidised bed. By keeping the gas speed at the above value in each stage, a minimum loss of adsorption agent during regeneration is obtd. The absolute minimum is normally reached at about 1.1 times the lift speed for the fluidised bed.

Title: Link for opposed cylinder internal combustion engine - has eccentric disc on crank between pistons which move in same direction
Inventor: NOLTEMEYER FRIEDRICH
IPC: F01B9/02
Filed: 1976-05-22
Abstract: The engine has two opposed cylinders (1, 2) on a common axis with a crankshaft (10) between them. Pistons (3, 4) in the cylinders are rigidly connected by a piston rod (7) so that they move in phase with each other. The piston rod has a bore containing an eccentric disc (9) having the same offset as the crank. This acts as a connecting rod. A disc (12) with twice the offset is attached to the crankpin (11) and is guided between parallel sides (13) of a slot in the piston rod (7). The slot is symmetrical to the bore in the piston rod. This provides a cardan type drive between cylinders which can be on the same axis without permitting the drive to rotate without motion of the pistons.
