Patent DE-2616789-A1 (DE)
Title: Tanks and pipes cast of aluminium alloy - with reduced wall thickness and casting skin left on inner surface
Inventor: HELLING WERNER DR ING
IPC: B22D21/00
Filed: 1976-04-15
Abstract: The wall thickness is reduced by at least 50% from the outside by machining, and pref. the workpieces are mfd. by sand casting, using Al-Si alloys adjusted to 760-840 degrees C prior to casting. The mould section which forms the outer surface of the casting is pref. structured so as to allow little or no reaction to take place with the molten metal. Machining may be performed by recessing to form reinforcing ribs, with direct extraction of the shavings at the cutting tools by means of channels. The components may be annealed at 520-540 degrees C and lacquered or coated with plastics on the machined surface. Components such as facing panels, frames, wheels and mast segments can be mfd. thus.

Title: Hairdressing comb for side and neck hair - has semicircular base, pointed main teeth and shorter gripping teeth
IPC: A45D24/36
Filed: 1976-06-16
Abstract: Semi-circular hairdressing comb, partic, for use in conjunction with an electric hair trimmer, for cutting and shortening hair in the nape of the neck and in the vicinity of the ears.

Title: Control circuit for electronically commutated DC motor - has two input differential amplifier in mirror connection to detector voltage outputs of Mall generators
Inventor: SOERENSEN ROBERT
IPC: H02P6/30
Filed: 1977-06-18
Abstract: The control circuit has at least one Hall generator detecting the instantaneous motor rotor position. Each semiconductor control element has a preamplifier in the form of a differential amplifier with two outputs. These are mirror-like connected to the detector voltage outputs of the Hall generators. Each detector voltage output of one generator leads to one amplifier plus input, and to the other amplifier minus input.

Title: Solar energy collector of all glass construction - giving a performance suitable for cold climates with no corrosion problems
Inventor: WILDE GERRIT DE PROF
IPC: F24S10/40
Filed: 1977-07-23
Abstract: A glass solar energy collector tube comprises an elongated cylindrical glass jacket in which is mounted a U-shaped glass absorber tube through which a heat storing fluid circulates in and out of the jacket. The lower half of the jacket internal surface is coated with a reflective lining, e.g. Al effectively forming a mirror which focuses energy on the inlet branch of the absorber tube. The remainder of the inner jacket surface is coated with a one way light transmitting substance to prevent re-emission of energy. The absorber tube may be blackened in one of several ways to improve absorption. It enters and exits from the jacket through a seal in a neck provided at one end of the jacket and is located and connected to the wall of the jacket by a set of glass ribs at the other end. The inlet branch of the tube is offset after entry so that is lies at the focus of the mirror while the outlet branch lies between the inlet branch and the axis of the jacket. The jacket is evacuated after assembly. The all glass collector is capable of being mass produced and has high evacuation and insulation capabilities which will withstand long periods of cold and cloudy weather. Heat loss is minimised and best use of the available solar energy is made. Problems due to corrosion are avoided by the all glass construction. The operating efficiency of the collector is independent of the element, temp. which is partic. important in cold climates.
