Title: Weather-resistant polyurethane foam with compact skin, prodn. - using foaming mixt. contg. aromatic poly:isocyanate and (cyclo)aliphatic poly:isocyanate
Inventor: MEYBORG HOLGER DR
IPC: C08G18/72
Filed: 1977-08-16
Abstract: Foamed articles having a compact outer skin and a cellular core and integral density distributing across article cross-section, are prepd. by forming a reaction mixt. contg. polyisocyanates, polyhydroxyl cpds. and blowing agents, opt. mixed with further isocyanate-reacting cpds. activators and further auxiliaries, in a closed mould. Novelty comprises using polyisocyanate mixts. of polyisocyanates (I) contg. aromatically bonded NCO gps. with polisocyanates (II) contg. aliphatically or cycloaliphatically bonded NCO gps., in mol. ratio (I):(II) 95:5 to 50:50 (esp. 95:5 to 80:20).

Title: Small heater esp. for dental laboratory or workshop - provides hot air jet and is pref. electrically heated
Inventor: BREUNINGER WILHELM
IPC: B01L7/00
Filed: 1977-10-05
Abstract: Appts. for heating small components or small quantities of materials comprises a tube equipped with an adjacent heater and connected to a compressed air source. The air blown through the tube is thus heated and the, hot, discharged air is used for the laboratory heating purposes. Used in any situation where a bunsen burner would commonly be used, esp. for dental mechanics, e.g. for melting wax in the mfr. of dentures. By using an electric air heater, the continual burning of the bunsen burner is avoided and thus a saving in fuel and excessive heating up of the laboratory is eliminated.

Title: Emergency lights test circuit - has timer triggered by simulated mains failure and controlling function checks
Inventor: STRAUSS MANFRED ING GRAD
IPC: G01R31/36
Filed: 1977-10-19
Abstract: The test circuit is used for emergency lights working off only one battery. It checks the functioning of the lights, the battery charger and the battery, under the control of a timer. The timer is started by a brief break in the mains supply lead for the lights or by operating an external test button shared by all the lights or by brief failures in the mains. During the simulated mains failure the lights are checked via the mains/standby changeover switch. The results of tests are retained in a store.
Patent DE-2747798-A1 (DE)
Title: Gelatin prepn. from animal waste - by alkali washing, reducing to a paste, neutralising, hydrolysing the resulting collagen and gelling esp. continuously
Inventor: OUDEM LEON
IPC: C09H9/02
Filed: 1977-10-25
Abstract: A process for prepf. collagen for gelatin mfr. from animal waste comprises treating the waste constituted by skin, sinews and tendons by the following successive operations. The material is first washed and defatted in soda soln. to expand the pores and facilitate the removal of blood and fat. Then the material is reduced to a paste by physical means. The paste is then neutralised, washed with cold water and pressed to remove any water leaving a cake of pure collagen. The collagen, opt. after drying and storing is hydrolysed to form a light density broth which gelled at low temp. and dried. A particular appts. feeds the broth near its gelling paint to a stainless steel band conveyor which circulates in an area kept at 0-10 degrees C esp. about 5 degrees C. From there, the film of gelatine passes to a second area via a series of belt conveyors passing from top to bottom; this area is maintained at 10-30 degrees C with a blower providing a feed of fresh air. The process which uses select waste materials enables a much shorter process time (1 -1 1/2 days, compared with 6-8 weeks, a continuous process, and much pleasanter working conditions.

One knife is movable by hydraulic actuators with respect to the other knife to define the elongated adjustable orifice. A crank and rack arrangement, carried by the head, is used to adjust the stroke of the hydraulic actuators, and thereby to regulate the orifice width.

Title: Delay control for instant picture camera - provides adjustable time delay for process rollers to avoid risk of vibration
Inventor: FAUTH GUENTER
IPC: G03B17/52
Filed: 1978-08-31
Abstract: The servo drive for the instant picture camera incorporates an electronic or mechanical delay timer to start the processing after the camera has been changed from the exposure mode. This gives the user time to lower the camera and reduces the risk of vibration. The time delay can be long enough to enable the user to operate a hold switch to prevent processing until it is convenient. This provides protection for the film in e.g. rain.

Title: Filament wound discs with stiffening rings - having twin discs wound together with windings round grooved side collars
Inventor: BANSEMIR HORST DR ING
IPC: B29C53/60
Filed: 1978-10-26
Abstract: Loads are applied to a structural component with collars wrapped with resin-impregnated filaments. A wound component is produced by winding round a rotating disc plus 2 collars which fit on axially, the resin-impregnated filaments pass continuously round the first collar on one side of the disc, over the edge of the disc, round the second collar on the other side, and back again over the edge of the disc; the finished assembly is divided into two mirro-image parts by cutting the filaments along the circumference of the disc and withdrawing the collar plus each half of the winding from the disc. The two collars are themselves wound round also. The windings round each collar produce a stiffening ring to distribute loads over the whole component, the number of such winding s is chosen to suit the loading which arise.

When the first thyristor conducts, the second thyristor also conducts and the capacitor and inductance form an oscillatory circuit, then the second thyristor is cut off first. The quenching voltage is stabilised by the section of the first thyristor.
Patent DE-2912391-A1 (DE)
Inventor: KORN VOLKER DIPL ING
IPC: A61B5/08
Filed: 1979-03-29
Abstract: For the measurement of functional respiratory volume, or respiratory capacities, apparatus are known including a respiratory bag which can be connected to a respiratory tube via a first valve system and which can be connected to test gas receptacles via an additional valve system and which exhibit gas analysis devices for measurement of the test gas concentration in the respiratory bag. Precise concentration measurements have been hitherto possible only discontinuously with chemical methods, or continuously with a large apparatus outlay (mass spectrometer). By way of a contrast, simple thermal conductivity sensors are unsatisfactory in measuring precision. According to the present disclosure, the concentration determination proceeds by means of a gas analysis device through continuous density determination of the mixture of test gas and respiratory air in the respiratory bag, for which purpose a measuring probe can be introduced into the respiratory bag by means of a separate connection, and the gas density-dependent measuring signal corresponding to the present test gas concentration, which signal has been tapped at the measuring probe can be directly displayed as the pulmonary function measured value (RV, FRC). In this manner the determination of respiratory volumes, or respiratory capacities, respectively, is substantially simplified.

Title: Electronic tester for coins - has staircase voltage generator with quartz controlled frequency and connected to counter of processor
Inventor: WOLFF WOLFGANG
IPC: G07D5/00
Filed: 1979-07-23
Abstract: Accurate electronic analysis of coins in game units rejects the incorrect coins using a staircase voltage generator (3) with quartz (1) controlled frequency. The coupled resonant circuits impart a phase shift depending on the time taken by the coin to pass the control station. This causes a change in the number of signals transmitted to a pulse counter feeding the data processor. The coded signals are transmitted to a resistances matrix through a gate connected to the constant voltage holding unit fed to the resonant circuits. Loading of the latter leads to the phase shift between the resonant circuits and the staircase voltage generator.

Abstract: The gripping tool is for the processing of sections of spectacle frames or similar. The object is retained by gripping segments, which are radially displaced in guides. The segments are sector-shaped, and are connected by elastic elements, to form a circular disc. The elements engage in the top of a guide block, and are together actuated by a central cone as in P2607506. The segments and the elastic elements are formed integrally, as an elastic solid cylinder. The upper-and lower side of the cylinder have radial notches, the depth and radial extension of which permit radial expansion of the cylinder, due to the central cone tension.
