Patent DE-2364975-A1 (DE)
Title: Continuous flow electrical heater - has heating element forming flow channel covered with hood
IPC: F24H9/20
Filed: 1973-12-28
Abstract: Bare helices in the channel are cooled by the running water, and are connected to a cut-out which disconnects them in case of danfer of overheating. A photoelectric cell monitors the helices and responds to visible radiation if they become incandescent in case of an overload. The cut-out is controlled by the above photoelectric cell. The heating element consists of a translucent or transparent material. The photoelectric cell is mounted at the narrow end of a funnel shaped light protecting tube whose wide end is close to the heating element. Should a heater from opaque material be preferred or necessary a light conveyor can be fitted with one end directed towards the heating coil and the other to the photo-electric receiver.

Title: Small vessel filling process - freezes filling liquid into tablet for insertion into vessel before sealing
Inventor: FOELLER WERNER DIPL ING
IPC: B65B63/08
Filed: 1974-02-08
Abstract: The process fills the vessels with the exact desired quantity of fluid before they are hermetically sealed. The fluid is frozen into tablets of the desired size, and in this condition is inserted in the vessel while still open on one side. Thereupon the vessel is sealed shut by application of its last wall section. The walls can be secured together by welding or soldering, and the process can be used for the production of thermostat capsules, or handling volatile liquids. The tablet can be enclosed in a wrapping impervious to liquid, which releases the contents before or on reaching operating temperature or pressure.

Title: Beer tank gas release valve - spring-loaded closure member allows gas to escape through single discharge tube
Inventor: WORCZINSKI GUENTHER
IPC: B67D1/12
Filed: 1974-06-28
Abstract: The valve for releasing gas from the inside of a beer tank is incorporated in a plate (12) mounted over the outlet (13) in the top of the tank, and has a single tube (1) through which passes a spindle (10) with a closure member (3) at the bottom, the spindle being pushed down by a spring (8) at the top, exerting pressure on a piston (9) attached to the top.

Title: Decorative band of flattened wire - has segments of S-shaped cross section bounding, and interengaging in, channels
Inventor: GANDELMAN MORRIS DAVID
IPC: A44C5/02
Filed: 1975-01-15
Abstract: Wire is wound into a flattened helix for decorative use as a band with an outer surface and a braided inner surface. In cross section, the wire has the shape of a stylised S. A planar segment forms the outer surface and another forms the inner surface. A middle segment extends transversely to the segments forming the surfaces and connects them together. The segments bound channels, opening oppositely, in the wire. Each channel has opposed inner sidewalls. The channels are wide enough w.r.t. the thickness of material of the wire, to permit successive flattened turns of the end segments to engage in the channels, but are narrow enough for the end segments to contact at least parts of opposed sidewalls of the channels, to bring successive turns of the planar segment forming the outer surface one on another and in a common surface.
Patent DE-2502784-A1 (DE)
Title: Phase-locked interpolating for continuous path machine tools - using selected frequency dividing ratios in closed loop controller
Inventor: TIETZE ECKART DIPL ING
IPC: G05B19/416
Filed: 1975-01-24
Abstract: A phase locked system for the interpolation of co-ordinate data for a numerically controlled machine tool system provides full synchronisation of control pulses. The interpolator consists of a pulse generator coupled to a filter-multiplier supplied with velocity data from store. The output frequency is therefore proportional to feed velocity and is passed over a selector controlled by a synchronising circuit to frequency reducing stages with the ratio 1:5, 1:6 and 1:7. A phase lock regulator receives the pulses and is coupled to interpolators for each co-ordinate axis, that provide multiplication by factors read in OR and AND gates generate outputs to the control circuit to close the loop.

Title: Pebble bed reactor vessel is closed by keyed blocks - with monitoring of second redundant key to detect failure of first
IPC: G21C13/08
Filed: 1975-03-14
Abstract: A redundant connection between two adjacent blocks of the top closure of a prestressed pressure vessel comprises two or more keys or pins; it is so designed that one key (or pin) only transmits the forces between the blocks under normal conditions, the second key constituting a reserve which comes into action only if the first key fails. The upper face of the upper, outer key is separated by a gap from the corresponding face of both the blocks; if the inner key fails, then the resultant closure of this gap is observed through inspection openings. Used esp. for a gas-cooled pebble-bed reactor, where the vessel closure comprises cast iron or concrete blocks. The observation of a change in the state of the outer key enables failure of the inner key - the first line of defence - to be detected.

Title: Coating chipboard with different materials - by applying glue to rough cut side, then coating with any material
Inventor: LANGNER GERHARD
IPC: B32B21/04
Filed: 1976-03-13
Abstract: Process for coating chipboard with different materials is performed by applying a suitable glue to the rought cut side of a chipboard panel which is coated on both sides with the same material, then adhering a coating by any material to the glue. Pref. the chipboard panel is coated on both sides with plastic material, then a wood veneer is adhered to one of the plastic coatings. The resulting chipboard is partic. suitable for kitchen cupboards. By not applying the glue directly to the chipboard, the latter cannot become warped. By using a conventional PVAc glue which is applied thinly, the glue does not penetrate e.g. a thin wood veneer coating, although the roughened plastic coating is impermeable to the glue.
