Patent DE-2525289-A1 (DE)
Title: Straightening unit on bar peeling machine - has roll centres and angles adjustable and rolls replaceable
Inventor: LINDEMANN HANS
IPC: B21D3/04
Filed: 1975-06-06
Abstract: Two-roll straightener for bar-shaped materials is distinguished by being able to vary the distance between the straightening rolls (1,2) and the angle between the axis (4) of the straightening rolls and that of the bar-shaped material (3), so that material of a much larger diameter can be polished. The hyperbolic straightening roll (1) is replaced by at least one roll whose application angle is smaller than that of the hyperbolic straightening roll (1) and its mating roll (2). The hyperbolic straightening roll (1) is replaced by two rolls of cylindrical or slight barrel shape so that guides are not necessary.

Title: Appts. making air holes in plasticised paper bags - using needles on drum containing heating elements or liquid
Inventor: URBANCZYK GABRIEL
IPC: B26F1/24
Filed: 1975-06-20
Abstract: The method is for introducing air outlet apertures in paper bags protected by means of intermediary layers of plastic sheeting. The needle puncture is effected at a temperature which is over the melting or welding temperature of the plastic. The method is applied by means of revolving cylinders or cylinder sections with counter holders, on which groups of needles are fitted. The cylinder or cylinder sections have hollow spaces in which heating elements are fitted and/or in which a hot fluid may be introduced. The rear ends of the needles project into the hollow spaces, and temperature adjustment and control devices are installed for the heating elements or hot liquid.
Patent DE-2533410-A1 (DE)
Inventor: MORIYA TOKIO
IPC: G04G9/12
Filed: 1975-07-25
Abstract: The liquid-crystal display device includes electrodes (2a and 3a) deposited in the form of transparent layers on the internal faces of the upper and lower plates (2 and 3). The electrodes (2a and 3a) serve, for example, to show a day of the week indication at a location which corresponds to the current day. The area occupied by these electrodes is delimited by the frames (5) affixed to the external faces of the two plates (2 and 3). These frames are permanently visible impressions. Affixing them to the two external faces of the device has the effect of avoiding, as far as possible, parallax when reading the indication of the day of the week. <IMAGE>

Patent DE-2612142-A1 (DE)
Title: Roller shutter locking device with alarm - has hook within roller shutter profile engaging with guide on lifting
Inventor: HERMANN BRUNO
IPC: E06B9/80
Filed: 1976-03-22
Abstract: The roller shutter locking arrangement consists of a simple hook fitted into one of the roller shutter profiles. This arrangement prevents lifting of the roller shutter from outside for breaking in purposes. It also triggers at the same time an alarm by a a contact on the guide rail. The hook (1) is guided into the roller shutter through a slot. When the roller shutter is lifted upwards then the spacing of the profile is reduced and the upper sloping part of the hook is turned into horizontal position. This pressure forces the hook into the guide rail and hence blocks the upwards movement of the roller shutter. The alarm arrangement contact is actuated at this point and the contact can be connected for electrical outside illumination or to mechanical ringing alarms.

Title: Programmable controller with graphic display - has profiled screen inserted between capacitor plates as impedance selector
Inventor: KOCH ARNIM DIPL ING
IPC: G05B19/12
Filed: 1976-05-08
Abstract: The programmable controller comprises a number of presettable impedances operating as a programme memory which are switched between a h.f. signal source and an impedance transformer. The rectified output of the transformer is proportional to the settings on the controller. The required programme is provided by a profiled, insulated metal screen (9) which gives a graphic display of the control levels. The sheet is inserted between pairs of capacitor plates of equal length and width (8/i - 8/xii). The plate is earthed. The capacitors thus formed are selected by switch combinations and connected between the signal source and the impedance transformer circuit. The number of switches required is kept low by grouping the input and output plates.

Title: Rectangular vessel for boiling beer wort - has heated base sloped up to central longitudinal ridge to improve wort circulation
Inventor: WOLFSEDER ALFONS
IPC: C12C13/02
Filed: 1976-07-23
Abstract: A beer wort boiling vessel of rectangular, horizontal cross-section. The vessel is of the type having a sloping base which can be heated to raise the temp. of the vessel's contents. The base of the vessel rises between the vessel sides in the form of a single ridge roof with its apex running parallel to, and pref. centrally between, the two longitudinal sides of the vessel. Pref. each end of the ridge does not reach the end wall of the vessel; instead it is joined to the bottom edge of the end wall by an inclined surface set at a slope which is steeper than the longitudinal sides of the ridge. The side slopes of the ridge are pref. symmetrical about the longitudinal centre-line of the tank. Each side slope pref. has a lower section at 10-20 degrees to the horizontal blending into an upper section at 10-20 degrees to the horizontal. Pref. all round the raised area of the base, a drain gully is formed at the lower edge of the end and side walls. The heated slopes to a central ridge of the base give rise to a convective circulation of the wort which tends to rise like a fountain above the ridge. This produces highly efficient heat transfer, improved coagulation and vaporisation. Additional heating surface is provided by the sloping up to the ridge.

Title: Drive and braking network for magnetic tape cassettes - provides accurate drive speed sand rapid braking using two independent spool drive motors
Inventor: SCHLOSSBAUER HUBERT DIPL ING
IPC: G11B15/48
Filed: 1976-08-13
Abstract: The drive and braking network is for use in magnetic tape decks and particularly for magnetic tape cassette decks. The transistor drive circuit and two independent reversible spool drive motors provide accurate speeds and very rapid braking. Two independent motors (2, 3) one for each cassette (1)spool are driven by a transistor amplifier which incorporates a feedback network monitoring the back e.m.f. of the motor being driven to establish an accurate running speed. When a brake switch (9) is closed a pulse is fed through a capacitance (13) into the feedback amplifier (6, 7) and simultaneously a constant current pulse (10, 11) is fed to the other motor (2). The tape is thus rapidly arrested.

Title: Drop=out recognition circuit for video tape recorder - has control voltage derived from periodically recurring frequency and used for threshold stabilisation
Inventor: SCHOLZ WERNER DIPL ING
IPC: G11B20/06
Filed: 1976-09-25
Abstract: The carrier for a visual display unit is modulated by the useful signal with a specified swing, and is demodulated in an f.m. demodulator which delivers a drop-out marking pulse when the carrier frequency exceeds a certain threshold, or drops below it. A control voltage (UR) derived from a frequency periodically recurring in the carrier, is used for stabilisation of the threshold (f1, f2, UT). The feedback loop producing the control voltage passes through an integrator (5) and an amplifier (6). In a more elaborate arrangement, a return signal from the control voltage line (UR) is passed through to a Schmitt-Trigger, in series with the frequency demodulator on the output side of the line.
