Title: Laser reproducer for video disc - restricts detector aperture so that effective light reception is less than distance between adjacent optically projected tracks
Inventor: KANAMARU HITOSHI
IPC: G11B7/12
Filed: 1976-11-19
Abstract: A reproduction system for an optical long-play video disc uses laser scanning, in which the effective light receiving width of the photodetector is equal to, or less than, the distance between adjacent optically projected tracks (B1, B2..) on the record. The effective length of the photodetector is one third to one fifth of the shortest recorded wavelength on the optically projected image. These dimensions may be derived from a light screen (16) with slits (16a) in the light path to the detector. The arrangement reduces crosstalk between adjacent track and raises the signal to noise ratio.

Title: Dough stress-release time reduction process - by briefly exposing dough to microwaves to give temperature rise
Inventor: SCHNEE WALTER ING GRAD
IPC: A21D6/00
Filed: 1976-12-20
Abstract: After a first mechanical shaping process, e.g. rounding off, the articles are exposed to a micro-waves for a max. of 10 secs., so as to give a temp. rise between2 and 3 degrees C. The micro-wave energy can be exerted both from above and below, simultaneously or nearly so, by means of suitably mounted emitters. Small-diameter articles can be treated either from the top or the bottom only. Micro-wave treatment can be carried on the articles passing between a rounding machine and a lengthwise roller. The process reduces the stress release time of mechanically-processed ad pre-shaped articles of dough, e.g. to be made into loaves of bread.

Title: Synthetic resin sockets for large diameter pipes - formed by enveloping elastic, silicone rubber mould on conical arbor
Inventor: MARUGG NIKLAUS
IPC: B29C33/50
Filed: 1977-02-03
Abstract: Sockets of synthetic material for connecting the ends of large diameter pipes, are manufactured by applying synthetic resin with reinforcement fibres, on to an arbor an allowing it to set. A mould of elastic, heat resistant material, e.g. silicone rubber, is first of all fitted on the arbor, and after the resin has set, both mould and socket are removed together from the arbor. The mould is then compressed and folded inwards, and withdrawn from inside the socket. Provides an arbor without segments, much lighter in weight, so that it can be handled without lifting tackle and the associated risk of accidents to the personnel. Grooves for seals, etc. can be formed inside the sockets as necessary, and the mould removed without difficulty.
Patent DE-2707688-A1 (DE)
Title: Protein(s) continuously concentrated from soln., esp. animal blood - by atomising in superheated steam and recycling of steam; used e.g. to produce fertiliser
Inventor: FIEDLER JUERGEN ING GRAD
IPC: B01D1/18
Filed: 1977-02-23
Abstract: A method for the continuous prodn. of solids, esp. proteined concentrates from aq. solns., esp blood, utilises live steam which is brought into contact with the soln.. The soln. is atomised in superheated steam and thus simultaneously dried, the protein concentrate is collected and removed and the cooled steam is again superheated and re-used in the process. Used esp. for the drying out and simultaneous sterilisation of animal blood, e.g. for use in a nitrogen-containing fertiliser. The contact time is extremely small due to the fineness of the atomised droplets; this reduces energy consumption and moreover results in min. decomposition of the protein. By recycling the steam from the atomisation process, there is no waste to present problems of disposal. Prodn. of odour is minimised.

Title: Laminated stator yoke made of steel strip - is constructed using two sub-yokes with strip in mutually perpendicular planes
Inventor: HEERLEIN MANFRED
IPC: H02K5/04
Filed: 1977-05-10
Abstract: The application is to stator yoke for electrical machines. The yoke is made as a continuous winding of steel strip or ribbon as in 2630806. The object of the present modification is to increase the mechanical properties of the finished yoke with respect to stiffness and stability. The yoke is constructed of two concentric sub-yokes. The inner concentric sub-yoke is wound by bending the steel strip on edge, giving axial lamination. The outer concentric sub-yoke is wound with the strip flat and thus gives radial lamination. The outer yoke may be made axially longer than the inner one in order to give a spigot for end shields.

Title: Braking cylinder with electrical switch - which is operated when piston moves too far and indicates excessive brake lining wear
Inventor: SIEBOLD MANFRED
IPC: F16D65/22
Filed: 1978-10-26
Abstract: The braking cylinder operates an electrical warning lamp when the travel of its piston (6) becomes unacceptably large. An electrical switch (18) is located on the outside of the cylinder and normally remains unoperated. The switch is operated when the piston travels too far as a result of excessive wear to the brake lining. The braking cylinder (1) pref. for use in compressed air brakes. If brake lining wear is dangerously large, the driver is warned of this fact by a lamp (25). The switch can be used both on the usual braking cylinders as well as on storage-spring braking cylinders. The switch is a simple conventional switch readily available commercially. Also, the current carrying parts of the braking cylinder do not have to be employed.

Title: Refrigeration plant used as heat pump - where heat of soln. created by dissolving ammonia gas in water is used as heat source
Inventor: BROCKS KLAUS-DIETER
IPC: F25B33/00
Filed: 1979-03-23
Abstract: The plant includes a film evaporator, which is pref. fed with an aq. soln. of NH3 and heated via. a burner; exhaust gases from the burner are used in a heat exhcnager. The NH3 formed in the evaporator flows into a liquefier and then into a collector in which the liq. NH3 is at e.g. 7-15 bars. The liq. NH3 is next fed intoa heat exchanger used to remove heat from another medium, e.g. air, and the resulting NH3 gas flows into a mixer head fed with the soln. leaving the film evaporator after most of the NH3 has been removed. The mixt. is then fed into an absorber; and the heat of soln. created in the absorber is used in a heating circuit. The soln. obtd. is then recycled to the evaporator. Refrigeration plants generate a large amt. of heat which is normally wasted; the invention is designed to exploit this inexpensive source of heat.

Title: Waste heat recovery of animal stables - by water spray nozzle mount in air extn. duct
Inventor: SIEMERS JUN BERNHARD
IPC: A01K1/00
Filed: 1979-05-04
Abstract: Parent patent No. 2727593 described a preheater which is built into the air extra system, esp. in henhouses for poultry farms, and is used to heat water. In a prefd. version, the preheater is designed as an air scrubber. Spray nozle on top of the extrn. duct sprays atomised water in counterflow to the ascending air. funnel of V-shape in a spherical section of the duct collects the heated water together with any solids washed out of the air. Suspended solids thus cannot clog the preheater; their removal ensures that no pollution is caused to the environment.
