Title: Water damage preventing valve - has diaphragm actuated by spring loaded pilot valve controlled by collapse of water soluble prop
Inventor: HUBER HEINRICH
IPC: D06F39/08
Filed: 1973-10-11
Abstract: The valve is intended for use in dwellings for prevention of water damage due to burst pipe or connecting hose. Prior designs work mostly on sudden changes in pressure or flow velocity following a pipe failure. The present arrangement works on the indication that water is present on the floor as a consequence of a burst pipe. The valve is installed in a riser and is fitted with a sensing box the top side of which is mounted level with teh floor. The box contains a spring loaded lever arrangement connected to a pilot valve and propped up by a water soluble element. The box top is provided with openings flush with the floor and water present on the floor enters the box, dissolves the prop, the pilot valve drops and closes the equalising orifice in the membrane in open position.

Title: Tensioning device for hydraulic hose on extending crane arm - has rod fastened at one end to arm and two pulleys at other end
Inventor: DEMLEITNER HANS
IPC: B66C3/20
Filed: 1973-10-20
Abstract: The main crane arm carries an extending arm. The winding drum controls the lowering and raising of the gripping fork by means of the cable passing over pulleys. A hydraulic cylinder is fixed to the gripping fork fed with pressure for closing the fork along the hydraulic base. The cylinder contains a return spring for opening the fork. For control of the hose, to avoid kinking, a rod is fastened at the outer end of the arm and carries at its other end two small pulleys between which the hose passes. Fixed to the cable drum is a half-size cable drum carrying a cable attached through a spring to another pulley over which the hydraulic hose passes. The slack in the hose is therefore controlled correspondingly with the movement of the hoisting cable.

Title: Low vibration, low noise flow mechanism - has mechanical structures affecting flow state advantageously in flow path
Inventor: MEIER GERD E A
IPC: F16L55/027
Filed: 1974-03-04
Abstract: Flow mechanism with low vibration and low noise for compressible and incompressible flow media, especially in the form of a throttle device where mechanical structures which prevent or eliminate variable flow conditions of the flow medium or which vary to the flow conditions for which the resulting vibrations or noise are tolerable, are exposed to the flow medium, have dimensions determining the flow condition and are arranged in or at the flow path. Specifically, the structure is one with small Reynolds number i.e. much smaller than 104 and specifically in the region of 1. Additionally the structure is so shaped that irregular variation in the flow medium parameters are prevented, especially on the downstream side of a cross-sectional variation in the flow path.

Title: Hydraulically operated clutch and brake - achieves low moment of inertia by housing springs in hub
IPC: F16D67/04
Filed: 1974-03-14
Abstract: The housing encloses the clutch and the housing encloses the brake. The hub is bolted at one end of the cover plate and at the other end to the hydraulic cylinder. The hub is provided with a number of axial holes which house the actuating springs. The periphery of the hub is provided with axial grooves to suit the clutch plates. The cylinder has similar grooves for the brake plates. The springs keep the brake engaged but when hydraulic fluid is supplied under pressure through the hole the piston overcomes the spring load, releasing the brake and engaging the clutch.

Title: Time recorder for clocking-in cards - printing head operated by card insertion into printing position
Inventor: TRISCHLER GUENTER DIPL ING
IPC: G07C1/06
Filed: 1974-05-17
Abstract: The clocking-in card is inserted perpendicularly into the time recorder, with a card carriage forming a stop for the inserted card, and an interrupter actuated by displacement of the card, to allow operation of the printing head, as the card reaches the printing position. A series of stops are combined to form a first element, defining the possible positions of the card carriage and the bolt cooperates with the stops and movable relative to the latter element with the card carriage. The engaged position of the bolt and the stop element is dependent on the card insertion and they are moved from this position by the card carriage as it reaches a stop, to actuate the interrupter.

Title: Overhead transmission line insulator suspension system - single and double insulator strings carry three phase circuit
Inventor: MORS HEINZ DR ING
IPC: H02G7/20
Filed: 1974-05-17
Abstract: On high voltage overhead lines carried on transmission towers, especially those of the portal type, it is required to guard against some of the consequences of a broken insulator string. The carrying system comprises a pair of insulator strings (2, 102), each consisting of two parallel assemblies, attached to the tower cross member (12), and a single string (3, 103) attached either to the same cross member or to a side member (17, 18) and to the free end of the pair. Also attached to the latter point is a V-shaped string (4). The conductors (8, 9, 10) are fastened respectively to the point of the V (5) and the common points of the strings (6, 7). Failure of one of the main suspension strings (2, 102) does not result in a line swinging against the tower thus causing an earth fault.

Title: Reducing copies photographically without development - with very high resolution capacity involves projection onto silver halide crystal
Inventor: HENIG GUENTER
IPC: G02B21/36
Filed: 1974-06-11
Abstract: Copies are reduced photographically by interposing between object and image carrier a reducing lens in the form of a microscope. A transparency of the object is subjected to short-wave and/or long-wave light which after passing through the reducing lens is directed onto the image carrier which is in the form of a single doped, photosensitive silver halide. By projecting the object onto a ground glass screen, a self-illuminating image may be produced: alternatively, the object may be focussed onto the reducing lens so that the short-wave and/or long-wave light fractions impinge upon the image carrier. The transparency may be in the form of a negative which is reproduced as a positive with short-wave light, or in the form of a positive which is reproduced as a positive with long-wave (lambda > 420 nm.).

Title: Undecenoic acid esters with hydroxy acids - prepd by reacting undeceonoyl halides with hydroxy carboxylic acid esters in the presence of a base
Inventor: KAISER KLAUS DR
IPC: C07C69/675
Filed: 1974-11-29
Abstract: Esters of formula CH2=CH-(CH2)8-CO-O-A, (I), (where A is the residue of a mono- or dihydroxy mono-, di-or tricarboxylic acid ester, the no. of C-atoms in the hydroxy carboxylic acid being 3-6, and one or both OH groups being esterified in the case of a dihydroxy acid), e.g. undecenoyl-lactic acid ethyl ester, have microbistatic or microbicidal properties, and inhibit the growth of pathogenic germs on the skin surface. They also inhibit undesirable development of the normal skin bacterial flora, thus preventing the decomposition of perspiration by bacterial action and consequently having strong deodorant properties due to inhibition of the formation of unpleasant-smelling perspiration decomposition products. The toxicity of (I) is low, and the cpds. are well tolerated by the skin.
Patent DE-2509785-A1 (DE)
Title: Extraction of viscous oils from bitumen- and tar-sands - by flooding with gaseous mixts of solvent and carrier gas
Inventor: ALLEN JOSEPH COLUMBUS
IPC: E21B43/40
Filed: 1975-03-06
Abstract: Highly viscous hydrocarbons are extracted, esp. from bitumen- or tar-sand deposits, by mixing a solvent which is liquid under the conditions in the deposit, with an inert carrier gas to form a gaseous mixt., which is injected into the strata through a bore-hole. The fluid produced, contg. crude oil, solvent and gas is removed through the same or another bore-hole. Cheap and readily available solvents can be used, including paraffinic types, which cannot be used alone, owing to blockage of the pores in the sands with pptd. asphaltenes. Advantages of gaseous and liquid solvents are combined injection of a non-condensable gas raising and maintaining pressure in the strata, increasing penetration rate and uniformity, and reducing the amount of solvent used.
