Patent DE-2444507-A1 (DE)
Title: Plastics tube continuously helically wound from strips on core - of end to end bars removed as tube is completed
Inventor: MIHIRA KAZUO
IPC: B29C53/82
Filed: 1974-09-18
Abstract: A device for continuously producing helically wrapped or wound tubes from lapped plastics strips comprises a revolving and axially travelling core bar, feed spools around it for the strips, and a cutter for cutting the finished tube into lengths. The core bar is constituted of a number of constituent bars joined end-to-end by spigot and socket joints with a region of reduced dia. at each joint. The constituent bars can be removed in succession and re-used as the tube is produced. The reduction in dia. at the joint makes the cutting position on the finished tube easily visible.

Patent DE-2552741-A1 (DE)
Title: Batch operated vacuum band filter - having cycle controlled by limiting reduced pressure in hook
Inventor: MILLER PETER ANTHONY
IPC: B01D29/09
Filed: 1975-11-25
Abstract: Control system for a batchwise vacuum filter process involves evacuating a filter chamber and then using the reduced pressure as a control parameter for the filtration and filter sealing operation. The vacuum is only produced by the vacuum pump connected to the filter unit. The rate of change of pressure in the vacuum chamber during the filtration is determined by a manometer the signal from which is used to control the feed value into the filter. After reaching a certain value, the inlet value is opened to commence the filtration. After the pressure in the filter chamber has dropped to a certain minimum value, the value is closed and the filtration terminated. The process ensures controlled feed, allows filtration even when seal is imperfect, keeps ingress of air to a minimum and ensures reliable termination of the sequence.
Patent DE-2553399-A1 (DE)
Title: Hair-care prepnns., e.g. shampoo, contg. polyamide - produced by polycondensation of adipic acid and triethylene-tetramine
Inventor: SCHEUERMANN FANNY DIPL CHEM DR
IPC: A61K8/88
Filed: 1975-11-27
Abstract: New hair-washing and hair-treatment agents contain (a) a slightly soluble, higher-molecular polyamide and (b) a tolerable non-toxic carrier. The slightly soluble higher-molecular polyamide is produced by polycondensation of approximately equimolar proportions of adipic acid and triethylenetetramine in a suitable solvent of 150-170 degrees C to a degree of polymerisation such that an aq. 45 wt. % soln. of the polycondensation prod. has a viscosity of 4000-6000 cP. The new agents improve the wet combing properties of the hair, and impart a soft pleasing feel to the dry hair. The hair can readily be styled, and static charging of the hair is reduced to a minimum. These beneficial effects are retained for a prolonged period, generally from wash to wash. The agents considerably increase the gloss of the hair, but rapid reoiling and the development of a stringy hair structure are inhibited and styling is held well. The agents are physiologically well tolerated, and there is no risk of irritation of the skin or ocular mucous membranes.

Title: Intensive care special power unit - has DC power supplied from isolated mains unit or HF AC supply well above mains
Inventor: ANNA OTTO PROF DR ING
IPC: A61B5/276
Filed: 1976-04-01
Abstract: The special power supply for the reduction of risk of electric shock is of special use in medical intensive-care units and generally meets the safety requirements of VDE 0107. The first method consists of a DC power supply supplied from an isolated mains unit remote from the operating a area, for powering electronic test gear, instruments, small motors, tools, lamps and the like. The second version entails a power supply using a special unit operating at a frequency well above mains 50 or 60 Hz i.e. in the region of 10 kHz so that in the case of accidental shock, no alternating currents at frequencies critical to the operation of human heart muscles are present.

Title: Semiconductor chip with controlled defects on surface - has uniform distribution of Hertzian fractures and microsplits
Inventor: SCHWUTTKE GUENTER HELMUT
IPC: H01L29/32
Filed: 1976-06-05
Abstract: A semiconductor chip which is manufactured with specific defects on one surface. This produces zones with an ordered arrangement of impurities, stacking faults, displacements, holes and other defects which can be reproduced and homogenously kept free. The defects are uniformly distributed across the surface of the chip and have a defined depth. The semiconductor material is made from silicon. The defects are in the form of Hertzian fracture cones and micro-splits. The surface is subjected to impact stressingly by placing a large number of spherically shaped objects on the surfaces which are then vibrated. The vibration frequently corresponds to the natural frequency of the chip.

Title: Aceto-acetate esters of butene diols - for use as copolymerisable monomers
Inventor: AREND GUENTER DR
IPC: C07C69/72
Filed: 1976-06-11
Abstract: Butene diol bis-acetoacetate esters are of formula CH3COCH2COO-R-OCOCH8COCH3 (I) (in which R is a gp. CH2=CH-CH2). (I) are prepd. e.g. by reacting a butene diol with diketene under base catalysis, pref. in inert solvent to reduce by-products from isomerisation of diketene. (I) are used as monomers for prepn. of copolymers capable of cross-linking reactions, e.g. with bifunctional ketones, aldehydes, acetals or hydrazides. They have less tendency for homo-polymerisation than known (meth)acryloyloxyalkyl aceto-acetate esters, allowing distn. of larger batches. They have higher copolymerisation rates than vinyl and allyl aceto-acetate esters, and smaller amts. can be incorporated for crosslinking of the copolymers, since each unit contains two reactive gps.

Title: Error signal display suppression arrangement - for multi-location dynamic visual display used with processor operating at two speeds
Inventor: MAEKAWA KOJI
IPC: G09G3/04
Filed: 1976-08-26
Abstract: An arrangement for use with display units for electronic processors with two operating speeds is designed for suppression of display errors. For processors dealing with large word lengths or complex computations a high operating speed is necessary. Display devices operate at lower speeds, so processors have a high speed operating mode and a low speed display interface mode. In order to inhabit display errors caused by the presence of two different pulse frequencies, the h. f. operating pulses are used to produce display blocking signals. The arrangement is partic. applicable to a multiple location dynamic visual display device.
Patent DE-2639120-A1 (DE)
Title: Temp. transducer for use in centrifuges - has fluid filled cell with refractive index varying with temp. in interference or Schlieren optical system
Inventor: HERMANNS BERND DIPL CHEM
IPC: G01K1/14
Filed: 1976-08-31
Abstract: The temperature transducer for use on rapidly moving specimens esp. in centrifuges, comprises a measuring cell (3) having two inner bores (1, 2) which are filled with a transparent medium. The medium in each cell chamber is such that its refractive index varies with temperature. The cell is placed in the ray path of an optical system (S) so that the differential temperature effect on the indices causes a shifting of the interference lines produced by the optical system. A detector converts the optical effect into a signal proportional to the temperature. Alternatively, a single chamber cell can be employed in which either interference or schlieren optics provide the output signal.
