Title: Grain drying plant regulating controls - has a three stage system for drying temperature, feed rate and air input mixture
Inventor: ZIEMS HORST
IPC: F26B25/22
Filed: 1974-03-02
Abstract: A three stage control system for a grain drying plant consists of an exhaust gas temperature probe delivering its result to potentiometer and comparing its value to a predetermined requisite value. If an imbalance occurs burner control activates burner proportionally and the rate of addition of damp grain is governed by control regulating feed conveyor and feed wheel. A third control circuit measures the moisture content of the dried grain and by comparison with predetermined values adjusts the air/heated air balanced flow by an additional control.
Patent DE-2416044-A1 (DE)
Title: Contact system for selectors etc. for transformers - comprises slip-ring, arc-shaped contact and movable contact system
Inventor: HEZ RUDOLF
IPC: H01H9/00
Filed: 1974-04-02
Abstract: The movable contact system consists of several, parallel connected contact bar pairs, mirror symmetrical to each other. They are resiliently mounted in an insulating supporting structure. The contact bar pairs spread out from a fixed contact to the slip-ring. Contact bar supporting springs in adjacent pairs are staggered with respect to each other. The contact bar pairs are separated by insulating spacers. The transference of heat to the cooling medium is thereby improved, and therefore the loading possibility is increased. The spreading of the bar pairs facilitates a larger flow of cooling fluid since the total cross section is enlarged.

Title: Reducing the gap between dough rolling machine bowls - erected automatically according to settingas dough rolling progresses
Inventor: ZOLLER ROLAND
IPC: A21C1/08
Filed: 1974-05-09
Abstract: The width of the gap between the bowls of a dough rolling machine is reduced in steps through a mechanism operated by an adjusting lever. Concentric rings of pegs on a support disc, act as stops for cams facing them. These are rotated relatively to the pegs in the radial groove of a disc with the help of the adjusting lever, which also serves to move them radially against the pressure of a spring and depress a plunger operating switches for the main drive and the reversal of the direction of rotation of the bowls. Each of the cams is also displaceable axially to the stops by an adjusting device with an eccentric finger which engages in a slot. Can be fitted as a modification to existing manually operated machines.

Title: Test piece heat expansion measurement - using laser beam interferometry to measure test piece dependent path length change
Inventor: LINSEIS MAX DIPL PHYS DR
IPC: G01N25/16
Filed: 1975-01-20
Abstract: The test piece is mounted in one of two grooves in a suitable carrier element, and a reflective quartz crystal is used to mark one end of the test piece in one groove and the other end in the other groove. A gas laser generated light beam is divided into two parallel beams, one down each groove. Each of these is reflected by the appropriate quartz crystal and directed to an inferometer by a semi-reflective mirror element. The interferometry patterns are then used in the usual way to detect path length changes, and thus to measure any expansion of the test piece.

Title: Corona discharge surface treatment of plastics sheet - by electrodes in direct contact with sheet permits reduced voltage
Inventor: LEEUWEN PETER VAN
IPC: B29C48/10
Filed: 1975-08-04
Abstract: A device for the surface treatment of a plastics sheet by corona discharge between two electrodes has the electrodes in direct contact with sheet as it passes between them. In one embodiment, the first electrode is a blade in edge contact with the sheet, the second electrode being the table supporting the sheet. In a variant of this, a roller is used instead of the table to support the sheet. Used esp. for treating a flattened tube where the rolls press the edges flat. This prevents a bulge forming at the edges. In all variants, a redn. in the applied voltage from about 10000-5000 V is possible by the use of direct contact. The direct contact does not prevent a correct corona effect, since this occurs alongside the contact point or line.
Patent DE-2550363-A1 (DE)
Title: Seals for the pistons of hydraulic accumulators - are arranged in axial contact in common grooves
Inventor: MUELLER HEINZ KONRAD PROF DR I
IPC: F16J15/3208
Filed: 1975-11-10
Abstract: The piston seals are arranged so that leakage of oil into the gas chamber is prevented. The soft seal of elastomeric material for the gas side and the tough seal based on PTFE for the oil side, which has a sharp lip facing the oil chamber pressed outwards by a soft expansion ring, are assembled in axial contact with each other in a common groove. Method ensures that as the piston moves towards the oil chamber, only the thinnest possible layer of oil is left on the cylinder surface, and that when the motion is reversed, the film of oil is not wiped into the gas chamber.

Title: System for blocking azimuthal angle of firearm - has angular range selectors preventing firing over certain angular ranges
Inventor: WEBER DIETER ING GRAD
IPC: F41G5/14
Filed: 1975-12-06
Abstract: The system is for preventing firing of a firearm within a given azimuth angle range. The boundaries of the firing angle range as well as that of the given blocked angular range are readily selected and rapidly changed. This arrangement can be used for example for blocking certain firing directions of a vehicle mounted firearm. The naval guns for example are also blocked from firing in certain directions. A first angle selector is provided and a second angular range selector subdivides the firing angle region into a number of sectors. One of these sectors is designated as a blocked sector. The output signal for instantaneous angular position is compared with the output signals of the first and second angular range selector. A logic circuit selects binary combinations for the blocked sector and the output signal from logic circuit is used for fire control.
