Title: powder coating chamber powder recovery system - has bottom of chamber formed as entry to cyclone separator with suction tube
Inventor: SCHAAD HANS J
IPC: B05B14/48
Filed: 1978-09-12
Abstract: The spray cabin (14) for coating components with plastics powder, has its floor shaped as a funnel with a side outlet (5) which forms a cyclone separator (5) for recovery of excess powder. The side outlet (6) from the bottom of the cabin is a suction opening forming the entry into the cyclone. The cyclone chamber can have a vertical suction tube (10) fitted with a filter (11) for separating residual powder before discharging through a vertical section (13) to an overhead discharge point. In one design, the bottom of the chamber can have a set of side by side cyclones across the bottom. They can be connected to a common suction pipe alongside the chamber. The separator system can use a quick action colour changeover system.

Title: Holding down a sodium-cooled fast reactor fuel element - by suction device through which coolant flows to prevent damage resulting from fuel melt-down
Inventor: GROETZBACH GUENTHER DIPL ING
IPC: G21C3/12
Filed: 1978-10-05
Abstract: Fuel element comprises a channel box contg. fuel rods and connected in leaktight manner to the lower grid plate. The box can be removed upwards out of the reactor vessel. The foot of the box or an insert which seals it to the lower grid plate contains a hydraulic holding-down device consisting of a lower and an upper tubular part connected respectively to the insert and to the fuel element foot or channel box by means of 2 sets of hollow ribs and which thus connect the interior of the holding-down device to the zone outside the channel box which is at lower coolant outlet pressure. The relative suction inside the holding-down device prevents uplift of the fuel element by the upward flowing coolant. The connection to the upper hollow ribs is provided by an upward tubular extension of the upper half of the holding down device, so that the openings of the two connections to the low pressure zone are as far apart vertically as possible. Natural or forced convection through the inside of the hydraulic holding-down device is afforded, so that it is kept cool, even if there is a fault which might cause molten fuel to drop onto the holding down device. Molten fuel would thus be kept inside the fuel elements and not allowed to spread.
Patent DE-2843399-A1 (DE)
Title: Heating system using natural power source - has high pressure pump delivering frictional heat from water circulating through immersed coil
Inventor: RAUTH PHILIPP
IPC: F24J3/00
Filed: 1978-10-05
Abstract: The method of obtaining heat for e.g. room heating can use a natural source of power to drive a wheel to operate a high pressure pump. This forces water through a closed circuit so that heat is produced by friction. A valve may be used for throttling the water, and another valve for increasing the pressure. The friction heat generated heats up water in a tank in which the coil forming the closed circuit is immersed. This is pumped around a circuit to heat up radiators for the room heating. A system can be designed to produce steam instead of hot water. The pump may be of rotary, piston, geared or membrane type, and the material can be cast metal, heat resistant plastics or steel. Other power sources are wind, water or solar power, and heat from a range of types of engines and heaters can also be used.
Patent DE-2846094-A1 (DE)
Title: Winder for optical fibre - has rotatable horizontal ring with fibre-receiving channel in top and guide roller on swivel arm above channel
Inventor: EITH GERHARD
IPC: B65H54/76
Filed: 1978-10-23
Abstract: The mechanism winds and unwinds optical fibre on to and from a roller. The roller is a hollow ring rotatable in a horizontal plane, in the upper surface of which an annular channel is provided into which the fibre is introduced via a guide roller which is in rolling contact with the ring over the channel. The roller may be carried on a swivel arm movable in a plane tangential to the channel. The arm may be adjustable radially to the ring by the amount of the width of the channel. This arrangement enables optical fibres to be wound and unwound with a min. of strain so that relatively simple spools can be used.

Title: Tennis racket handle - is covered with amine-cured bisphenol=A di:glycidyl ether which deforms ergonomically but recovers initial shape after use
Inventor: WHITTINGHAM GRAHAM
IPC: A63B49/08
Filed: 1978-11-06
Abstract: Handle, e.g. for a tennis racket, is relatively easily deformed when gripped so as to fit the shape of a hand, but reverts to its initial shape when released. The handle comprises a resin having Shore-D hardness 50-85, esp. 60-75 at 15-35 degrees C. The resin is an amine-hardened diglycidylether of bisphenol-A, and is directly cast upon the handle core, or may have been moulded as a strip or casting that is subsequently applied to the handle core. The resin is covered by a bushing.
Patent DE-2855412-A1 (DE)
Title: Electric coffee machine with flow heater - has specially designed fresh water container ensuring constant level of water column
Inventor: TRAUNSPURGER GUENTHER
IPC: A47J31/057
Filed: 1978-12-21
Abstract: The machine is fitted with a regulator (16, 18) which includes the fresh water container, so as to maintain at the inlet side of the heater (4) the height of the fresh water column acting on the heater at a constant level. This is possible if the fresh water container is designed like a bird drinking trough, or if it is mounted on springs. Alternatively, the regulator can have an intermediate container which is connected between the fresh water container and heater and which has a supply valve controlled by a float. The constant level of the water column ensures even brewing temperatures and reduces the noise hitherto caused as the container empties. Steady, even water percolation is also attained.

Title: Control circuitry for telephone exchange - operates PROM according to whether microcomputer, acting as de-centralised control, receives commands from central processing unit
Inventor: SCHOENE LOTHAR
IPC: H04Q3/545
Filed: 1980-05-09
Abstract: A decentralised, microprocessor-assisted telecommunications control (DSE) receives - over receiving line groups (E1 to En) - the command signals (SB). These are connected to a data receiving circuit (DE), consisting of addressable multiple registers, and to a programmable read-only memory (PROM 1) having address input terminals (A to H). According to the address selected, a definite output word appears on one of the output terminals (Qo to Qn). These output control words are constructed to suit the local requirements of the decentralised exchange system and are consecutively received by the microprocessor (DSP) via the data receiving unit (DE) in a sequence determined by address-enable inputs to AND-gates (UGO to UGn). By adding one further bit to the command words of the central exchange, the data store (PROM 1) triggers a monostable flip-flop (MF) with a short set-reset period during which a relay (RL) is closed through which any coincident information (on output Qo) is given priority by the microprocessor.
