Title: Protection of pharmaceutical tablets, pills, etc. against moisture - by coating with wax or oil without solvent and then further coating in known manner
Inventor: SUWA KANAME
IPC: A61K9/28
Filed: 1976-04-01
Abstract: The process avoids the alterations in shape or compsn. which can occur when H2O or an organic solvent is used in the coating medium. Suitable waxes are ceresin, wool wax, paraffin wax, and hydrogenated castor oil. Suitable oils are acetylated monoglyceride and liquid mixts. of satd. triglycerides. In an example, 9,800 ascorbic acid (I) tablets, consisting of 50 mg (I), 200 mg lactose, 5 mg maize starch and 1.25 mg magnesium stearate, were treated in a coating vessel with distilled acetylated monoglycerides ("Myvacet 9-40) and 2.5 g finely powdered hydrogenated castor oil ("Cuture HR"). The vessel was allowed to rotate or 5 mins. The treated tablets were then coated with a suspension of 1.0% carboxymethyl cellulose, 1.0% polyvinyl pyrrolidone ("Collidone 25"), 50.0% saccharose, 1.0% finely divided silica, 6.8% talc, 2.5% CaCO3, 2.0% gum arabic 6.0% colouring lacquer and 29.7% H2O. After storing for 4 weeks at 40 degrees C the (I) content of the treated tablets was 99.3% compared with 93.2% for untreated tablets.

Title: Readily released locking system for projectile fuse cone - has locking pin held in a deep hole and readily depressed
Inventor: HARGELL PER
IPC: F42C19/02
Filed: 1976-04-05
Abstract: The closing component for the projectile fuse housing consists of a nose cap which is held by a screw thread in the threaded hole in the fuse housing. These fuse components are prevented from rotating relative to each other in assembled state and the gap between them is sealed. However the fuse can be readily dismantled by using simple tools should this be necessary for example for replacement of parts or for modification. The nose cap (5) and the fuse housing have opposite end faces (4, 6) which come into contact on assembly. A hole (13) is drilled through two components at their edge and this hole passes through the contacting faces. A locking pin (12) driven into this hole is shorter than the hole depth in the fuse housing and is driven into the fuse housing if it is necessary to unscrew the fuse cap. A new pin is readily installed.

Title: Spark pistol with spectral analyser - for determining the composition of metal samples using TV display
Inventor: STRICKER FRIEDRICH DR
IPC: G01N21/67
Filed: 1976-06-11
Abstract: The chemical compsn of metals is determined by objective spectral analytical technique. Metal vapour is produced by hand held spark gun, the radiation from which is transmitted to a spectroscope by means of a flexible light conductor cable. The spectrum produced by the refraction prism is fed onto the light sensitive layer of a TV camera. It is then re-produced on a monitor screen. Here it can be compared with a reference spectrum produced by an auxiliary device. This consists of a reference object which is also sparked and the signal fed back by means of a flexible light conductor. A reference spectrum can also be reproduced by a video recorder. Used esp. for use in stainless vessel warehouses where a large variety of different grades of steel are stocked.

Title: All-weather combined harvester - uses waste heat to warm fresh air for grain drying
Inventor: BIESTERFELDT HARALD
IPC: A01D41/12
Filed: 1978-06-19
Abstract: The all-weather combined harvester has a device for utilising the waste heat for grain drying or straw predrying. The hot exhaust gases, coolant etc. are fed through one or more insulated pipe systems to an insulated container, in which are liquid or solid heat-storing materials which are heated. Fresh air cavities pass through the container. The fresh air is heated in the cavities and fed to the grain drying equipment by a thermostatically controlled blower. Alternatively, the resulting heat energy can be fed through cavity systems through the grain drying plant. In this case, heat demand, speed etc. are controlled automatically and manually.
Patent DE-2833412-A1 (DE)
Title: Vertically perforated heat insulating brick - has hole dividers offset extent reduced to counteract shrinkage effects
Inventor: KELLERER JOHANN
IPC: E04B2/14
Filed: 1978-07-29
Abstract: A number of rows of holes are aligned transversely to the direction of heat flow, in the brick with vertical perforations. The intervening internal stem pieces are offset. The extent of offsetting of these stem pieces relative to each other is reduced, compared with full offsetting, to fill gaps. It may increase from a min. extent on one edge, at least, to a max. in the brick centre area. This prevents any increase in the area of overall perforation inside the outer stem pieces relative to hole alignment, in spite of shrinkage consequent on rapid drying, without complications in manf.

The pivots are fitted with fixed discs around which are looped flexible drives in crossed loops between the two systems so that a pivot action on the one section causes the other to pivot in the opposite direction. No complex gears are required with the flexible bands transmitting the torque. The operator is able to sit facing the direction of travel while using his body to pull the sweeps rearwards for maximum effect.
Patent DE-2839995-A1 (DE)
Title: Absorption refrigerator with heated discharge - has refrigeration output controlled by quantity circulated by jet pump
Inventor: LANGENBACH ROLF DIPL ING
IPC: F25B15/00
Filed: 1978-09-14
Abstract: The increased pressure and temperature of a refrigerating agent provides discharge of vapour from absorption agent. The latter is then liquefied in a cooled condenser at discharge pressure, but lower temperature, dissipating heat in the process. The agent then passes via a regulator valve, reducing the pressure, to a vaporiser, where heat is absorbed. The vapour-free agent flows through a return pipe to an absorber, and there draws in a liquefies the vapour from the vaporiser. Condensation and solution heat released in the absorber is conducted away be a coolant. A pump returns the agent from absorber to discharge, increasing the pressure. The return pipe incorporates a jet pump, actuated by the vapour-free agent. The degree of refrigeration is controlled by regulation of the quantity of refrigerating and absorption agent circulated by the jet pump.
