Title: Replaceable seatings for shut-off valve - incorporated in high pressure expansion valve for natural gas in stages
Inventor: DREIDEMIE EUGEN
IPC: F16K41/00
Filed: 1973-08-04
Abstract: The expansion valve is of cascade type capable of reducing pressure from 400 atmospheres to zero by expansion through a series of stages, used particularly for natural gas. An outer body has a screwed cap which holds the removable insert ring. The inner conical part of the valve lies within packing ring. The inner conical part of the valve lies within the body projecting outward through the open top. It also is made in two parts screwed together to clamp a ring with a seating face to close onto the seating face of the ring. In use erosion and corrosion of the seating faces occur and by manufacture as inserts, which may be of austenitic stainless steel or of tungsten carbide cost can be saved.

Title: Hydrophobic solid carriers - contg inorganic non absorbent cpds and silicones, suitable for pesticides
Inventor: MURRAY PETER HUGH
IPC: C05G3/00
Filed: 1973-10-23
Abstract: Solid, hydrophobic carrier materials consist of a mixt. of (a) one or more finely divided inorg. cpds. with (b) one or more silicone cpds; the inorg. cpds. or substances being (pref. talc. pyrophyllite, kaoline, chalk flour, ground slate, kieselguhr) with a particle size 0.075mm. The carrier materials are partic. suitable for pesticidal substances (e.g. insecticides, fungicides or anthelmintics), herbicides and fertilizers.

Title: Hair washing machine with warm water supply - has three-way valve draining off initial cold water
Inventor: SIEDLER KLAUS
IPC: A45D19/00
Filed: 1974-01-16
Abstract: The hair washing machine which supplies water at a sufficient pressure to wash and massage the head and hair has a thermostatic three-way valve mounted at the inlet side of the spray nozzles. In order that cold water does not spurt out onto the user's head, the water remaining in the pipes, from the warm water supply to the spray nozzles, and which has now cooled down, is drained away. The heat-sensitive element in the warm water supply at the three-way valve gradually displaces the ball of the valve as warmer water is supplied until the inlet to the spray nozzles is released and the drainage opening is shut off. The water which is drained off can be recirculated back into the pressure-less warm water container where it is reheated.

Title: Enamelled, sheet steel cooking pans - with uniform metal thickness, and bottom expansion-compensating enamel layer, preventing distortion
Inventor: MESSMER ERNST
IPC: C03C8/18
Filed: 1974-06-05
Abstract: Enamelled cooking, baking or frying pans having a concave bottom, made from sheet steel and provided with ground enamel layers on both sides, a top enamel layer in the inner of the utensil and on the outer side of its side walls, and an expansion-compensating, metal powder-contg. enamel layer on the underside of the bottom, are improved in that the compensating layer is made from enamel contg. as additives finely dispersed graphite, SiC (opt. partly replaced by quartz sand) and a metal powder. The thickness of the compensating layer decreases from the centre (=1.5 mm) to the periphery of the bottom correspondingly to its concavity. The expansion-compensating enamel layer prevents deformation of the bottom of the pan at elevated temp.; the necessity of a thicker bottom being eliminated, and the utensil being made entirely from a uniformly thick steel sheet (0.8-1.5 mm). Process is thus simplified and less steel is used.

Title: Automatic fitting seat belt - with safety catch on movable belt mounting for collision protection
Inventor: BLUEGGEL ERWIN
IPC: B60R22/06
Filed: 1974-09-25
Abstract: The automatic fitting seat belt has the shoulder strap mounting fitted to slide along a guide rail along the top of the car door, and is operated by cable drives on either end of the slider. The slider moves on guide wheels and the release cable is coupled to the slider by means of a pivotted lever which is spring loaded to swing outwards. As the slider is pulled backwards into the belt on position, with the other cable (release) slack, the lever drops into a cut-out in the side of the rail to lock the slider in position, so that it cannot be displaced by any collision forces. To release the slider the release cable is pulled to pull the lever flat and also pull the slider.

Title: Androsperm- or gymnosperm- enriched sperm prodn - utilizing the higher motility of androsperms
Inventor: SOKOL KURT DR MED
IPC: A61K35/52
Filed: 1974-12-03
Abstract: In a process for obtg. sperm enriched with andro- or gymnosperms in amts. sufficient for insemination purposes in which the sperm fromone ejaculate is contacted with a tract of a spermatozoa motility stimulant and after a prolonged contact time the tract is divided into two parts, the part nearest the start point having an increased gymnosperm content and the part remote from the start point having an increased androsperm content, the sperm is divided among several tracks simultaneously and the motility stimulant is formulated as a cryobiologically active protective colloid by adding suitable additives. Immediately after the sepn. of each of the several tracks into 2 parts, each part is frozen. Further ejaculates from the same donor are subjected to the same procedure until the collected andro- or gymnosperms contain at least 30-60 x 106 sperms/cm3 (i.e. the amt. required for an acceptable insemination success rate). Immediately before insemination, the collected androsperm or gymnosperm-enriched material is thawed, pooled, and opt. concd. by removing as far as possible the carrier consisting of motility-increasing material and protective colloid. The procedure makes effective use of the finding that androsperms have greater motility than gymnosperms in order to give sperm enriched in either of the two sex determinants. This permits an infant's sex to be predetermined at the time of insemination, which can be desirable on social or (in the case of animals) economic grounds. In addition, the procedure permits the accumulation of an effective amount of sperm in the case of prospective fathers who are infertile due to low sperm counts.

Title: Semiconductor component with diode - has planar transistor structure on substrate rated for max. inverse current amplifying
Inventor: SCHWARZ JOACHIM ING GRAD
IPC: H01L29/08
Filed: 1975-04-15
Abstract: The integrated semiconductor component has a planar transistor structure on a substrate, the component having parallel connected emitter and base zones operated as a diode. The transistor structure is so rated that its inverse current amplification is as high as possible. Preferably the junction surfaces between the emitter (4) and the base (3) zones are also selected as large as possible. The surface ratio between the emitter and base zones are chosen to approximate the value of unity as much as possible. The maximum possible inverse current amplification reduces considerably the lossy current. The p-conductive base zone is preferably deposited in a n-conductive island (2), forming the collector zone.
