Title: Moulding workpieces - in moulding boxes moving from first posn to second posn on transport belt
Inventor: ULRICH WERNER
IPC: B29C44/34
Filed: 1971-12-03
Abstract: Workpieces are produced by moulding or foaming in a moulding box with upper and lower parts, a closing device, and >=1 de-aeration channel, this moulding box moving on an endless transport belt. The moulding box is first at least partly filled with the liquid material for the workpieces in a first position in which the mould sepg. plane defined by the upper and lower parts is approx. horizontal, closed by oppositely moving the upper and lower parts, and is then swung into a second position around a predefined angle dependent on the geometrical shape of the finished workpiece and its arrangement in the moulding box, so that the inlet cross section of the de-aeration channel on the inside of the moulding box reaches its highest possible position, in which the enclosed air can escape, the liquid material in the moulding box solidifying in this second position. Air enclosed in the moulding box is completely removed during moulding.

Title: Castor with inner ball bearing - has castor tyre firmly connected to ball bearing outer race
Inventor: HARTMANN EWALD
IPC: B60B33/00
Filed: 1972-07-04
Abstract: The castor wheel consists of an inner ball bearing to whose outer race is firmly connected the castor flexible outer part and has a simple set of ball bearing shells, without any special moulded tracks. The rubber tyre is bonded directly to the outer race of the ball bearing. In order to absorb axial forces, without jamming the castor, the inner bearing race is made narrower than the outer one, while the outer shell has the same width as the tyre. This simple design provides for an economic, mass produced castor.

Title: Drying of cracking gases with organic liqs. - with hydrogenation of absorbed diolefins in the liq. before regeneration, to prevent polymn.
Inventor: BRANDL ANTON
IPC: C10G45/32
Filed: 1973-01-31
Abstract: Gases contg. polymerisable unsatd. hydrocarbons e.g. styrene, 1,3-cyclopentadiene and other diolefins, as obtd. from cracking processes, are dried with org. liqs. e.g. glycols and the charged liq. is hydrogenated before regenerating by heating to remove water. Pref. part of the hydrocarbons are removed from the drying liq. by pressure release and stripping before hydrogenation stripping may also be carried out during hydrogenation in a catalytic reactor. Hydrogenation of diolefins prevents formation of polymer deposits in the regenerating column, esp. when operated at 180-210 degrees C to obtain a residual water content of 0.1 wt.%.

Title: Cement firing shaft kiln - with adjustable bank and controlled draw rate of gases through the charged material
IPC: C04B7/44
Filed: 1973-03-13
Abstract: The vertical shaft kiln is stepped at the bottom where it comprises a bank for the charge material to temporarily settle on so that the flames from a burner can be directed at the exposed surface. The backing wall in this zone behind the charge material consists of a porous plate behind which is a collection box to which continuous suction is applied to ensure controlled rate of drawing of flue gases across the kiln shaft. The porous plate is pref. sloped at the same angle as the exposed surface of the banked material. The method results in uniform firing of the charge material which may be cement, lime, magnesite dolomite etc.
Patent DE-2332169-A1 (DE)
Title: Electronic guidance control of face cutter for coal mines - avoids cutting into roof material above seam
Inventor: ADDISON GEORGE THOMAS
IPC: E21C35/08
Filed: 1973-06-25
Abstract: When a cutter passes up and down the face it carries a radioactive device to measure the density of the material remaining after each pass. The roof material caves easily and these cables can be detected and the information used to control the knife. In the electronic apparatus the frequency of the output signal of the detector is fed to two circuits, the first of which has a long time constant and is used to guide the machine normally. The second circuit with its shorter time constant can detect the relatively higher frequency signals when the detector passes a cave. This circuit can then take over the control of the cutter, stopping it until the lower frequency signal is detected again. The system operates reliably in damp or dusty atmospheres.

Title: Removing dust from tanned skins such as chamois - permeable conveyor belts support skins held at full width
Inventor: TRIET HANS
IPC: C14B1/00
Filed: 1973-09-11

Title: Rapid fruit and vegetable juice fermentation - by lactic acid bacteria or yeast addition and fermentation at higher temp.
Inventor: GOEBEL ARMIN
IPC: A23L2/42
Filed: 1973-10-26
Abstract: A rapid fermentation system for fruit and vegetable juices is based on a concentrate of microorganisms which, in the case of lactic acid bacteria, are added at a rate of 5000 to 20,000 mill./cm3 (10,000-20,000 moll./cm3). The juice is left to feremtn at 36-38 degrees C for 50 to 90 min. until the pH-value has dropped to 4.0-4.2. The fermentation is then interrupted and the juice is pasteurized (80 degrees C) or cooled. This greatly reduces the otherwise required fermentation time of 12-16 hours. It does not affect the taste or colour of the beverage.

The first control circuit for one direction consists of two transistors controlled by a manual switch; the second control circuit for the opposite direction consists of two further transistors controlled by a second manual switch. A third switch switches off the supply to the motor, as does an overload protection transistor.

Title: Multi-layered insulated wall construction element - with smooth finished outsides fixed to inner insulating layers and filler layer
Inventor: KOCZMAJEWSKI BRUNO
IPC: E04B2/86
Filed: 1974-03-26
Abstract: The sandwich-type element incorporates hard outer layers and immediately adjacent insulating layers inside these. The two former layers are smooth on their outer sides, needing no plastering and ready for the direct application of paint. On the inner side they are firmly bonded to the layers of insulating material. This in turn has a bonding or cementing structure, producing connection between the inner layers and the filler layer, in the assembled condition. Spacing of the inner layers is effected by spaces embedded in them, in the required symmetrical plane. For use as an external wall component the weather-exposed outer layer may incorporate a water-repellent compound. There may be intervening hollow spaces for service ducts. Such elements are easily manipulated, hoisted and transported.

Abstract: The gas-cooled thyristor stack is fitted with a heat sink on each side of each disc thyristor. Each heat sink is provided with a tube along the sides of the thyristor stack. The free end of each heat sink has cooling fins. Each of the two tubes is L-shaped and together they form mirror images about the longitudinal centre axis of the stack. The two tubes are connected to a T-joint by two short flexible sections of tube. The structure of the stack improves the conduction of heat away from the thyristors and at the same time is compact.

Title: Cauterising rig for instrument sterilisation - with rotatable turn table passing articles through gas heated zone
Inventor: SCHULZ PETER DR MED
IPC: C12M1/26
Filed: 1974-04-23
Abstract: Kolle loops and other instruments used in serology and bacteriology are sterilised and cauterised in a motor-driven turntable in which the instruments are mounted in an inclined vertical position. They revolve around a central gas burner and pass through the zone of heat at a speed adequate to burn off organic matter. When cool they are removed from the turntable and replaced by others. This saves the tiresome manual sterilisation of the instruments. It saves labour which may total 2 to 3 hours per day.

Title: Water cooled reactor fuel can with internal oxide coating - preventing metal water reaction if can bursts
Inventor: HOFER GERHARD DR
IPC: G21C3/20
Filed: 1974-06-19
Abstract: A fuel rod for water-colled nuclear reactors comprises a zirconium or niobium alloy fuel can contg. a pure nuclear fuel filling; the inner face of this can, in addn. to the outer face, has an oxide coating at least 2 mu thick, to prevent a reaction between the can material and water penetrating into the fuel rod in the event of a fault. Partic. in the case of a burst duct, leading to loss of coolant and consequent temp. rise in the fuel rods, the provision of an intentional oxide coating on the inner face, in addn. to that normally present on the outer face, ensures that the reaction which takes place between water and the can material anove 900 degrees C is considerably slowed down or arrested. Thus further excessive damage to the can is prevented.
