Patent DE-2623385-A1 (DE)
Title: Tube drawing system with dies and mandrels - pulls tube through successive dies using floating mandrels of different sizes
Inventor: UHLMANN OTTO
IPC: B21C1/32
Filed: 1976-05-25
Abstract: The tube drawing machine has a drawing die (6) and a floating mandrel (4) held within the tube in the region of the die. The tube is drawn through the drawing units consisting of dies and floating mandrels and drawing elements. The drawing method is economical due to favourable ratio between the drawing and the idle time. The series connected mandrels are inserted into the tube in relation to the die positions. The tube length is pulled through the first die until the first die first mandrel reaches its correct position. The other mandrels are then separated from first one and guided to the next drawing stage. These operations are repeated up to the last but one drawing stage. The tube is dented behind each die to such an extent that the depressions contacts the given mandrel. These mandrels can be connected by snap-connection or with a magnet.

Title: Lysine prodn. from (1)-alkoxycarbonyl-(2)-alkoxy-piperidine - by reacting with hydrogen cyanide and ammonia and hydrolysing the product
Inventor: WARNING KLAUS DR
Filed: 1976-07-29
Abstract: In the prodn. of lysine salts, a 1-alkoxycarbonyl-2-alkoxypiperidine of formula (I): (where R1 is 1-4C alkoxy and R2 is 1-4C alkyl) is reacted with at least equimolar amts. of HCN and NH3 and opt. CO2 in aq. or aq. -alcoholic reaction medium at 70-150 (90-120) degrees C under substantially autogenic pressure and the reaction product is hydrolysed. In an example, 17.3g (I, R1=OCH3, R2=CH3), 5.4g HCN and 15.8g NH4HCO3 in 60 ml water are autoclaved 4 hrs. at 100 degrees C. After cooling, 5-(4-methoxycarbonylbutyl)hydantoin, m.pt. 146 degrees, crystallises out in a yield of 12.3g. Conventional hydrolysis with conc. HCl gives lysine in 93.2% yield.

Title: Sheet lifting mechanism from stack - is controlled by pneumatic switch actuated by pressure alteration in suction piping
Inventor: KISTNER HERMANN
IPC: B65H3/08
Filed: 1976-08-25
Abstract: The mechanism lifts off and extracts individual sheets from a stack, having a lifting device with suction cups moving down onto the topmost sheet and up again. Its drive is controlled by the vacuum in the supply piping, which is in turn dependent on the presence or absence of a sheet at the cups. Operation of the lifting device drive (24) is controlled by a pneumatic switch or valve (29), actuated by pressure alteration in the suction piping (34). The drive can be an electrically-controlled crank mechanism, with a pneumatially-operated control switch. The crank can perform a single revolution at the time, lifting the cup off the stack and returning it. The rise in pressure in the pipe when a sheet is pulled off the cups actuates the switch.

Abstract: The box end cover automatically unfolds under pressure, and is for boxes of hexagonal cross-section. It comprises a hexagonal flap (20), attached to the end of one of the sides, and of the same size as the box end. This flap is glued to an erection flap (21) opposite to it that as the two opposite sides (3, 6) to which they are attached are pulled further a part, the two flaps are pulled into a position at right angles to the other sides (2-7). The erection flap can be glued roughly to the centre of the main one, and can be the shape of half of it. The sides adjacent to the flaps (2, 4, 5, 7) can have supporting flaps glued to each other, to form an end support.

Title: Remotely controlled external vehicle mirror - has servo driven shaft to mount jointed stalk which allows manual adjustment
Inventor: UHLIG HELMUT
IPC: B60R1/062
Filed: 1976-10-13
Abstract: The external driving mirror (11) is mounted on a servo driven shaft (2) at a set angle, so that when the shaft is rotated the mirror assumes different viewing angles. The mirror stalk is further jointed (7) so that a manual adjustment (10) provides coarse settings, while the servo drive provides the fine adjustments. A single servo motor is used (3) with only a reversing control. The mounting linkage is simplified and the combination of coarse manual, and fine servo control allow rapid and accurate setting of the mirror.

Patent DE-2659280-A1 (DE)
Title: Seal ring for plug-in pipe connection - has triangular seal rolled into position between coaxial pipe ends on assembly
IPC: F16L21/025
Filed: 1976-12-29
Abstract: The plug-in pipe connection has a stepped location hole (12) which provides a radial gap between the two assembled, coaxial pipes (2, 17). The radial gap allows the location of a static seal ring (1), whose cross section is basically triangular. On assembly, the seal ring is placed at the front end (15) of the location sleeve (2). When the straight tube end (17) is pushed into the location bore (12), the seal ring (1) is trapped between the inside and outside diameter of the two tubes. The ring is thus rolled-over about its profile axis so that after assembly of the pipe connection, it is placed in the middle of the joint.
Patent DE-2708231-A1 (DE)
Title: Large food processing vessel fat separator - has surface jets, helical conveyor and heated collector tank
Inventor: WEILER WALTER
IPC: B01D21/24
Filed: 1977-02-25
Abstract: Floating matter is removed from the surface of the water in the separator for e.g. a large food processing tank by jets (18) which propel the matter towards a conveyor. Intended particularly for the removal of floating fat, steam or hot water jets are used. The helical conveyor (9) is housed in an enclosure (6) of semi-circular cross-section which may be rotated to adjust the height of the rim (7). The solid matter passes from the conveyor into a tank which is heated periodically for removal of the fat. The process facilitates simple, non-manual disposal of fat without the heavy water consumption of homogenisation.

IPC: B60T7/04
Filed: 1977-04-16
Abstract: The brake and accelerator pedal are combined into a single, large pedal which is tilted about its middle line, to either side to operate either the brake or the accelerator. The driver's foot does not have to leave the pedal at any time. The pedal has a convex shape, with a seam separating the two sections and defining the tilt line. The driver can feel the tilt line with his foot. The brake section is wider than the accelerator section for a failsafe operation.
Patent DE-2717148-A1 (DE)
Inventor: HOFER-BRUNNER EUGEN
IPC: H03F9/02
Filed: 1977-04-19
Abstract: In the magnetic amplifier, a reactor coil (2) is connected in anti parallel with a series circuit of a control coil (4) and of a control device (5) which can be a control resistor, a control reactor or a control capacitor. The start (As) of the control coil (4) is connected to the end (EDR) of the reactor coil (2) and the control device (5) is connected between the end (ES) of the control coil (4) and the start (ADR) of the reactor coil (2). Furthermore, the anti parallel circuit (2, 4, 5) is connected in series with a differential coil (3) in such a manner that the end (EDF) of the latter is connected to the end (EDR) of the reactor coil (2) and the start (AS) of the control coil (4). This magnetic amplifier does not need any premagnetisation and does not cause any unwanted delay in operation. It can be used in control technology, particularly when controlling metering systems in chemical industry, in control systems for temperature, air humidity and fresh air in airconditioning systems, in automatic controls for machines, for example machine tools, or in controlling alternating currents and electrical powers, in controls for light and heat and in computer controls. <IMAGE>

Title: Journal bearing with low length to dia. ratio - has support body with bore formed by load carrying and radially offset shaft control parts
Inventor: PIATT JAMES ARTHUR
IPC: F16C33/10

The sidewall of the bore is formed by a load carrying part and a shaft control part which is offset radially from the load bearing part by a shoulder. The load carrying part of the bore sidewall includes a segment which directly bears the shaft load. The control part of the bore sidewall includes a segment which is located across the bore from the segment of the load carrying part of the bore which bears the shaft load. This segment of the control part of the bearing is for restricting lateral movement of the shaft within the bearing bore so as to control the location of the shaft.
