Title: Disc filter with ring shaped discs - having central passage for slurry inlet and cake removal aided by vibration
Inventor: BROKHAGE JOSEPH DIPL ING
IPC: B01D25/168
Filed: 1977-02-19
Abstract: Separation of solids from slurries is carried out by a bundle of filter plates mounted in the form of a column in a housing. Each has a space between the next to allow cake to collect, and has passages through to allow filtrate to drain away. The housing has a slurry inlet and an outlet for the filter cake. Vibrators are fixed to the housing to vibrate the cake off the plates. The plates are clamped around their outer edge and the cake is vibrated towards the centre. The central holes form a passage for removal of the cake. Each plate is in the form of a ring and the free openings form the inlet for the slurry and the outlet for the cake. The process is for use filtering slurries. It gives a filter which is compact and simple in construction, in which the residual volume of unfiltered material is kept to a min and can be fully filtered in a short time. It produces a dry, pressed cake, easily removed from the filter housing.

Patent DE-2710145-A1 (DE)
Title: Windlass with coaxial rope drum - has drum and head on common drive shaft with freewheel and clutch
IPC: B66D1/74
Filed: 1977-03-09
Abstract: The windlass has the winder head coaxial to the rope storage drum. The head (2) and the drum (1) are mounted on a common drive shaft (4) with freewheel and slipping clutch. To give the necessary rope tension for the winch to operate, the difference in diameter between head and rum can be used, in conjunction with the slipping clutch. When paying out the rope (10), the freewheel can be arranged to allow the drum to turn freely in the unwinding direction while at the same time it is slightly retarded by a permanently functioning brake (8). The design avoids the need for a separate motor to drive the drum, giving a more compact arrangement.
Patent DE-2711653-A1 (DE)
Title: DC drive for e.g. submarine - has series resistances on motors for failsafe drive on circuit failure
Inventor: KRANERT KLAUS DIPL ING
IPC: B60L15/04
Filed: 1977-03-17
Abstract: The DC drive for a boat, especially submarine, has several DC supplies linked to several motors via common feed lines and controlled by a thyristor control for series and parallel drive. Each motor is fitted with an electronic control circuit incorporating a series resistance and a shunting loop. The shunt operates after a set time delay after the motor has started, so that the resistances prevent high initial current drain. Failure in the control circuits disconnects the drive so that a manual connection can be made to selective motors for series and parallel connection as required.

Patent DE-2723021-A1 (DE)
Title: Electricity generating plant with closed working cycle - uses ammonia as working fluid, in water or zinc-ammonia complex for energy pick=up phase
Inventor: SINGELMANN DIETRICH E DIPL ING
IPC: F01K25/06
Filed: 1977-05-21
Abstract: The electricity generating plant with a two-fluid energy carrier system uses a low latent heat of evaporation, high vapour specific heat, fluid such as ammonia as working fluid; water or e.g. Zn chloride-ammonia complex which absorbs, releases working fluid easily as auxiliary medium. The two are brought together in a cooled absorber, replacing the condenser. A feed pump conveys the mixture through an economiser into an evaporating, where the fluids reseparate under heat. The working fluid passes through a superheater before driving the turbine; the auxiliary fluid returns to the absorber via an energy exchanger. This comprises a heat exchanger using a circulating liquid which returns extracted heat to the mixture in the economiser, and a pressure energy absorber which assists the feed pump motor.
Patent DE-2723785-A1 (DE)
Inventor: SCHAEFERS HEINRICH B
IPC: B23B51/00
Filed: 1977-05-26
Abstract: The drilling tool has a tool shank which can be driven in a rotary and axial manner. The drilling shank (30) carries a drilling head (35) for drilling the cylindrical hole section as well as blades (47) which can be displaced axially and laterally outwards and are carried by blade carriers (44). Passages (38) open to the outside are cut in the drilling shank. Side blades (40) from elastic blade carriers (44) and carbide blades (47) brazed to the blade carriers are guided in the passages (38) in a longitudinally displaceable manner. The base of each passage (38) is curved in a slight parabolic shape and runs obliquely to the outside in the direction of the drilling head (35). To produce a tapered hole, the end of the blade carrier (44) carrying the carbide blade (47) slides over the curved section (39) in the base of the passage (38), in the course of which the carbide blade (47) increasingly emerges from the periphery of the drilling shank (30). <IMAGE>

Title: Material metering equipment from hopper - has three perforated plates in contact and sliding against each other to free central plate openings
Inventor: CHAMBON RENE
IPC: B65G65/48
Filed: 1977-07-14
Abstract: The system extracts, meters and delivers free-flowing material from a hopper, having a perforated plates moving in relation to each other so as to meter set quantities of the material and deliver it. When the plates (1, 2, 3) one above the other and in contact with each other, are set in motion, the material in the openings in the middle one is enclosed between the upper and lower units. The upper plate is then moved in relation to the other two, which are temporarily stationary, allowing material to flow into the openings in the middle plate. The lower one is then moved in relation to the other two, temporarily stationary, freeing the central plate openings so that material can flow out. The cycle is then repeated, to refill these openings via those in the upper plate.

Title: Pulsed radar with magnetron transmitter - has twin channel video stage with digitiser to replace coherent oscillator
Inventor: LIEM TIANG GWAN DIPL ING
IPC: G01S7/292
Filed: 1978-06-09
Abstract: The pulsed radar system is designed to reduce the need for compromise between stability and rise time when using a coherent oscillator.

Title: Heat insulating vertically perforated brick - has reduced staggering of holes in offset rows between internal partitions
Inventor: KELLERER JOHANN
IPC: E04B2/14
Filed: 1978-07-29
Abstract: A series of rows of holes (1-3, 5) aligned across the direction of heat flow have the separating inside stems mutually offset in the brick's lengthways direction, so that webs in one row are offset opposite hole columns in the next, in the brick which is vertically perforated, for max. heat insulation. Here the extent (v) of offsetting of inside webs (6) relative to each other is reduced by an interval from full offsetting. The extent may increase from a min. at one edge, at least, to a max. in the brick's centre area. The offset hole columns is pref. symmetrical relative to the central area. This ensures a min. number of holes in each row despite shrinkage resulting from quick drying.
