Patent DE-2705518-A1 (DE)
Title: Ironing machine for clothes - having motor-driven shoe and roller, and an epicyclic gear box, to which roller drive is locked to drive shoe
Inventor: WAHNSCHAFFE KLAUS-DIETER ING G
IPC: D06F67/10
Filed: 1977-02-10
Abstract: The motor-driven planetary pinion, meshing with an annulus, is mounted on an arm coupled to a crank for the drive to the shoe. The annulus, which is coupled to the roller, has a brake which is held off on the shoe encountering the roller by rotation of the arm. The arm can be coupled to the crank by a redn. gear, so designed to prevent reverse movement of the shoe with the roller running. The annulus can be coupled to the roller via a further redn. gear.

Title: Cooker inside brewing copper - enclosed by open=ended guide tube for reduced consumption of cleaning fluid spray
Inventor: WOLFSEDER ALFONS
IPC: C12C13/02
Filed: 1977-02-24
Abstract: A beer brewing copper, esp. for use as a wort pan, is equipped with a built-in tubular cooker. A guide tube, open at both ends, surrounds the cooker at acertain distance and can be lowered over it during the rinsing of the cooker by a cleaning fluid. This reduces the amt. of cleaning fluid (NaOH) required for the regular rinsing of the cooker and speeds up this process. The lifting of the guide tube in normal operation prevents any disturbance of the normal operation.

Title: Equal thrust control circuit for lifting loads - has working cylinder piston mechanically connected with piston of control cylinder
Inventor: THIELE HORST
IPC: F15B11/22
Filed: 1977-04-28
Abstract: The installation serves for lifting loads of different magnitudes uniformly. The installation according to the design adjusts itself automatically to varying loads regardless of viscosity interferences. The installation consists of multiple circuits laid out identically. Each circuit consists of working cylinder (2Z) with corresp. control cylinder (S). The cylinder is connected to the working line (A) and fluid supply line (01). Each circuit is further fitted control valve (V) and the installation is fitted with equal thrust gear (G) contg. cylinders (S11-S14) and pistons (K11-K14). If during lifting pressure in one of the cylinders fails, due to the mechanical connection with the control piston the control pressure increases and closes the control valve, so that the working piston cannot move.

Title: Purification of liquid stream by multistage contact with solids - using airlift pump to move solids from one cell to the next to give countercurrent contact
Inventor: EBERLE SIEGFRIED-HELMUT DIPL C
IPC: C02F1/52
Filed: 1977-07-09

Patent DE-2747268-A1 (DE)
Title: Vessel for bulk storage of hot water under pressure - consist inner welded shell with outer laminated interlocking reinforcement bands, useful as power station heat store
Inventor: KLOSKA GEORG DIPL ING
IPC: F16J12/00
Filed: 1977-10-21
Abstract: Multiple layer vessel consists of a series of profiled interlocking bands supporting an inner lining. This lining is made from plates of an easily welded material to form a leak free inner shell. The mechanical strength of the vessel derives from the outer support bands. These consist of very rigid, hardened bands, having interlocking teeth. In each successive layer, the bands are joined to each other. The inner vessel consists of a flat walled, welded structure with profiled bands welded onto the outer side. The support structure is built from this. Used for storing heat at power stations using water at 123 bar and 325 degrees C. It is uneconomic to construct large storage (10,000m3) using conventional pressure vessel techniques. However high strength steels weld poorly. The method described uses a relatively thin wall support vessel to act as the seal while the laminated structure in high strength steel provides the mechanical strength.

Title: Dual purpose double skinned light dome - has solar energy collector between skins with opaque part area insulating layer
Inventor: HANKEMEIER JUERGEN ING GRAD
IPC: E04D13/03
Filed: 1977-11-14

Title: Aperture setting control for cine camera - pulses signals from photocell using oscillator and measured film frequency
Inventor: MAYER HERMANN
IPC: G03B7/085
Filed: 1978-06-30
Abstract: Cine camera with lens aperture control operates by light reflected through the shutter mechanism onto a photoelectric cell when the camera is running. When the camera is stationary the continuous output singal from the photoectric cell is combined with the output of a chopper pulse oscillator at the input to the measuring circuitry. The output frequency of the chopper oscillator is the same as the running frequency of the camera shutter so that exposure measuring circuitry can operate according to a pulsed output from the photoelectric cell through the shutter when the camera is running, or chopped by the oscillator pulses when the camera is stationary.

Title: Overheating safety valve for solar energy collector - is thermostatically opened to circulate cooling air through storage tank jacket
Inventor: RAETZ GEB BURGERT ROTRAUT
IPC: F24D19/10
Filed: 1978-09-21
Abstract: Between the storage receiver wall of a solar energy collector system and the insulating jacket of the receiver, there is an air gap. The insulating jacket is formed by separate segments the inner surface of which is undulated, and the ribs between the undulations rest against the receiver wall and form the air gap which is open downwards to the outside, and is connected at the top a flue closed by a thermostatically controlled flap valve. When the temp. of the water in the receiver reaches say 60 degrees, a bellows attached to the wall opens the valve and prevents a build-up of vapour pressure which would be damaging to the system.

Filed: 1978-10-10
Abstract: Rotor is mounted on a vertical shaft rotating inside a container, with rotary cutter or comminuter, esp. for machines for working up, comminuting and/or regenerating thermoplastics scrap. There are 2 disc segments which are rigidly connected or connectable with each other in such a way that >=1 segment of 1 disc faces the other disc so that a slot is defined between the discs as they rotate. Both discs are composed of segments that are complementary w.r.t. one another at least near the cutters.
