Patent DE-2846838-A1 (DE)
Title: Charging circuit for lead-acid battery - initiates charging at lower voltage limit and terminates it at upper limit using switch and rectifier
Inventor: MOHR PETER
IPC: H01M10/44
Filed: 1978-10-27
Abstract: The battery charging circuit disconnects the charging current when the battery voltage exceeds a given upper limit. The charged battery is discharged until a given lower limit is reached. The two limits are functions of temp. The relationship between charging time and discharging time depends on the battery state. The battery is connected via switch to a rectifier. The battery has its measured terminal voltage used to operate a trigger. The trigger output is amplified and controls the switch.

Title: Blow moulding oriented polyethylene terephthalate! articles - by axially stretching to a point where subsequent blowing causes strain crystallisation
Inventor: BRADY THOMAS EDWIN
IPC: B29C49/64
Filed: 1979-02-17
Abstract: An oriented polyethylene terephthalate article is made by heating a preform to a temp. in the molecularr orientation range (75-110 degrees C), axially stretching the perform to a pt. wher further stretching in another direction will cause strain induced crystallisation, and then blowing the axially stretched preform to the final shape, during which blowing, strain-induced crystallisation occurs to give a higly biaxially oriented article. For PET of average mol.wt. of 36000 and an inherent viscosity of 0.6 the min. axial stretching must be about 2.75. For PET of mol.wt. 65500 and an inherent viscosity of 0.9 the min. axial stretch is about 2.6. The size of the subsequent stretching in a different direction is of no consequence. The high molecular orientation achieved enables stronger articles to be formed for the same prior art. stretch and thickness, or alternatively, the same strength articles to be formed with less stretch and thickness.
Patent DE-2906628-A1 (DE)
Title: Sledge with steering system - has resiliently supported tilting seat and connections allowing runner to tilt for negotiating curves
Inventor: SCHEIB RUDI
IPC: B62B13/12
Filed: 1979-02-21
Abstract: The sledge has two runners (16) supporting two cross members (18) with central supports (32-38) which carry the seat (40). The cross members are also connected at each end to outer longitudinals (30) forming rectangular linkage with corner connections (31). This allows the runners to move so that one runner is advanced ahead of the other, for a short distance. The connections (20) between the runners and the cross members each consist of a U shaped strap (21) integral with the runner with sloping arms between which is retained a shaped block (22) integral with the cross member. A quick release pin (23) passes through the arms and the block, acting both as a securing device and hinge pin. The hinged connections allow both runners to be tilted by tilting the seat, when negotiating a curve. This action is assisted by the movement of one runner ahead of the other. The longitudinals (30) are used for gripping and steering. Resilient suspension is included.

Patent DE-2935000-A1 (DE)
Inventor: VIGNON LOUIS
IPC: D01H4/00
Filed: 1979-08-30
Abstract: The object of the process is to produce a yarn comprising a core of continuous filament and a sheath of staple fibers. The staple fibers are delivered to a suction surface comprising a perforated collecting surface exposed to relative suction in a suction zone, the fibers being conveyed in a current of air moving virtually at right angles to the surfaces of two counter-rotating friction discs having narrowly spaced opposing faces defining a gap. From the suction zone, the staple fibers are transferred, generally at right angles to the axis of the current of air, into the gap. The continuous filament is united with the staple fibers in the suction zone, and both components are twisted in the gap between the counter-rotating friction discs.

Title: Metal grid mat handling device - uses forwarding electromagnet positioned above mat pile carried by height adjustable table which is moved sideways for loading
Inventor: ANDERS HELMUT
IPC: B65G59/04

Title: Atmospheric condenser pressure and temperature protection equipment - has safety standpipe using condensate as barrier water
Inventor: PAWLIK HERBERT ING GRAD
IPC: F28B11/00
Filed: 1979-11-17
Abstract: The equipment protects atmospheric condensers from excess pressure and temperature, having a safety standpipe (1) in which condensate is used as barrier water. On blowing through as the result of excess pressure in the steam pipe (3), this water is fed into the condenser (2), typically via the breather pipe of the latter and a steam-and-water separator vessel (4). Dimensions of the standpipe, apart from those necessary to form a sealing water column and a passage for the maximum steam quantity, can be such that the volume of barrier water will always flood the condenser.
Patent DE-2947215-A1 (DE)
Title: Film-sound tapes drive synchronising unit - has slots set midway between sound tracks for sprocket wheel drive and direction sensing operational modes
Inventor: GIGGE REINHARD
IPC: G11B23/04
Filed: 1979-11-23
Abstract: To ensure synchronous drive of sound tapes with film tapes narrow slots are added midway between two sound tracks. These slots are not only used for driving the tape positively by sprocket wheels, but may also contain directional indicator holes or slots to sense the direction of movement. Intervals between holes are determined by the slowest tape speed of 4.75cm/s and may be made identical with the pitch used in film tape. Sound tracks would not be affected if the slot width remains below 0.7mm. The arrangement aids transverse alignment of the tape with the positions of the tape heads.

Title: Viewfinder for SLR camera - has both automatic and manual focussing, adjustable as required
Inventor: JEHMLICH HANS DR
IPC: G03B19/12
Filed: 1980-03-15
Abstract: An sLR camera with automatic focus has a manual override to provide special effects. The image is focussed on a matt screen formed by a liquid crystal plate which is normally transparent and changed matt by applying a control signal. The liq. crystal plate (5) is positioned along one face of the penta-prism (3) for optimum focus setting. A manual switch (8) inhibits the automatic focus control (7) and provides the matt signal to the liq. crystal plate. The signal can be a repetitive pattern to allow normal viewing as well as focus control.

Title: Integrated circuit including HV, UHF and T-squared-L transistors - has combined quasi-substrate and low UHF transistor capacity, and doped material forming insulation zone
Inventor: SCHWABE GERHARD DIPL PHYS DR R
IPC: H01L21/761
Filed: 1980-04-26
Abstract: This integrated circuit combines a high voltage planar transistor with a UHF and an I-squared-L technology transistor. Fabrication processes are minimised by producing a quasi substrate for the UHF- and I-squared-L transistors with the first diffusion process which produces the insulation zone of the high voltage transistor. Moreover, the UHF transistor capacity is reduced, thus increasing its frequency range. The doped material forming the insulation zone of the high voltage transistor is first diffused into the silicon substrate (1) and is extended into the region of the other two transistors before the application of the first epitaxial layer (2). More material of the insulation zone is applied to part of the second epitaxial layer (3) and diffused into part of the first applied insulation zone.

It may be used alone or in combination with an oestrogen as a contraceptive agent, esp. in women suffering from high blood pressure or in whom oral contraceptives cause hypertension. (I) may also be used for the treatment of premenstrual disorders. It is similar to progesterone in its combination of gestagenic and anti-mineralocorticoid properties, with the advantage of oral activity.

Title: Bottle washing machine preceding main washing machine - uses hot alkaline water discharged from main machine for bottles travelling in holders
IPC: B08B9/30
Filed: 1980-07-31
Abstract: The bottle washing machine has a conveyor which carries bottle holders containing empty bottles under washing fluid falling from above. It has a vessel under the conveyor to receive the washing liq. A pump sucks the liq. from the vessel and discharges it into the enlarged end of a discharge tube without generating pressure. The other end of this tube discharges above the bottle conveyors. The circulating liq. is alkaline hot water which is discharged from the main bottle washing machine which follows it, so that heat is saved.
