Title: Vehicle rubber tyre with anti-slip tread - which contains sharp steel, quartz, plastics or granite particles
Inventor: LINDER ALFRED
IPC: B60C11/14
Filed: 1976-01-26
Abstract: The running tread of a rubber tyre contains, embedded in it, relatively sharp-edged and -pointed particles, such as steel, quartz, plastics, granite, to impart anti-slip characteristics to the same. As the tread is gradually worn off in use, these rough particles are laid bare and improve the road holding of the tyre. They are claimed to successfully replace prior-art spikes on tyre treads, which are now prohibited (in W. Germany). The tyre tread construction does not add to the price of a tyre nor is its wt. increased.

Title: Strip material dipping device - with low speed entry and higher speed exit to and from trough
IPC: C23G3/02
Filed: 1976-03-27
Abstract: The device is for dip treating, painting etc. of flexible strip material. The strip is fed into the container (1) through motor (70) driven rollers (3) and forms loops round two longitudinal rollers (5, 6). These rollers are driven so that the loops move along them, the strip being dipped at least partially into a liquid in the tank (1). The average speed of the strip is controlled by alternating two modes of drive. The first mode has the input speed slightly greater than the removal speed, resulting in an increase of the length of strip in the tank. The second mode uses a much higher rate of removal, resulting in a rapid decrease in the length of strip in the tank.

Title: X:ray appts. imaging transverse section - has overlapping detectors interrogated at twice signal frequency
Inventor: LUDERER GUNTER DR ING
IPC: A61B6/03
Filed: 1976-06-10
Abstract: The invention applies to an apparatus in which a flat, fan-shaped pencil of X-rays is received at a set of intensity detectors placed behind the object under investigation. The object is X-rayed from many directions in succession, and the received signals converted into a visual image of the section. The detectors (41, 42....) overlap, and are to be interrogated by the image converter (50) at a sampling frequency equal to twice the signal frequency. The sampling frequency thus accords with the sampling theorem.
Patent DE-2628128-A1 (DE)
Title: Thermal storage warm air heater - has vertical air inlet of larger cross section than outlet to give uniform flow through horizontal heating passages
Inventor: HOENIG BRUNO
IPC: F24H7/04
Filed: 1976-06-23
Abstract: The heater has a thermal core in which electric heater elements are embedded. Air is supplied by a fan at the bottom of the heater into an inlet passage which runs vertically up through the core. It is connected by horizontal heat absorbing passages which discharges warmed air through the bottom of the heater. The inlet passage has a larger cross section than the outlet passage. This increases the static pressure in the inlet passage and reduces it in the outlet passage. As a result the pressure difference causing flow through the horizontal passages is more nearly the same for all the passages and flow through them is more uniform.
Patent DE-2640160-A1 (DE)
Title: Foam separator with internal baffle - being vessel with vapour space and liquid space and narrow gap between
Inventor: BOB REINHOLD ING GRAD
IPC: B01D19/00
Filed: 1976-09-07
Abstract: Separation of gases or vapours from a liquid with a tendency to foam is done in vessel with upper vapour space and lower liquid space, together with feed line and lines to remove liquid and vapour. Immediately below the feed line is a device over the surface of which the incoming feed is spread to form a liquid film. This serves to divide the vessel into the gas and liquid spaces. The two spaces are separated by this device. The inlet pipe is directed down on to a distributor which spreads the feed over the conical device. It enters from the side but turns through 90 degrees and lies on the vessel axis. There is a circular slot which forms the passage between the two zones. For use in separating vapours from liquids with high foaming tendencies because of their low surface tension. The use of packings is known, but these have high pressure drops, tend to block and become unsterile food and pharmaceutical applications. The system described avoids this.

Title: Fruit pectin deriv. prepn. - from low esterified pectin mixt. with phosphate in aq. acid soln. by addn. of metal salt
Inventor: FOX GERHARD
IPC: A23L29/231
Filed: 1976-10-29
Abstract: A fruit pectin deriv., esp of apple pectin, for making jellies having a partic. low dry solids content, is prepd. by using a pectin raw material having a metal bonding capacity of 30-140 g. metal salt, calculated as CaCl2, for each kg. pectin at degree of esterification 30-40 (35-38)%. A soln. having pH 4.4-4.8 is prepd. from the pectin raw material, water and phosphate, at 10-90 degrees C. A determined metal salt quantity is added to the sln. and the pectin deriv. formed is pptd. from the soln. and dried. The phosphated Ca pectinate obtd. is soluble in cold and warm water, and forms a soln. having low viscosity, which allows easy working. The Ca-phosphate Cpd dissociates at a given pH in cooking, to form the original low esterified pectin in a defined Ca- and buffer concn. A uniform Ca pectinate gel is formed. The pectin deriv. is similar to amidised pectin as regards Ca- and pH-dependence.
