The combustibles have a potential energy of approximately 6,000 BTU's per gallon.
Patent DE-3042366-A1 (DE)
Inventor: CAP HEINRICH ING GRAD
IPC: G11B15/48
Filed: 1980-11-10
Abstract: The winding and rewinding of the audio tape in magnetic-tape apparatuses must take place as quickly as possible. In this respect, stopping the tape plays an important part. Mechanical brakes are subject to high wear and electrical brakes are very elaborate. What is problematical in this case is detecting the standstill phase, which until now required quite complex electronic equipment. The invention specifies a circuit of simple design for braking to a standstill when winding or rewinding, to be precise by ensuring storage of the last given winding command by a logical input combination of gates (Q1, Q2) and only connecting through the output of the gates (Q1, Q2) when the winding command has been cancelled. <IMAGE>

Title: Data registers with josephson contacts - interferometer and josephson contacts being linked to enable setting, resetting and data shift
Inventor: MISCHKE GERALD DIPL ING
IPC: G11C19/32
Filed: 1980-12-24
Abstract: These shift registers which use interferometers with Josephson contacts include circuit elements which allow setting and resetting of individual storage cells and shifting of data. This is achieved by linking inductive interferometers in branches along the register and Josephson contacts across the register with other interferometers via one of more Josephson contacts. Current induced in a cell (6) by a write current (Jw) divides into currents (IAK,IBK) via Josephson contacts (2,4), with the greater part flowing to the inner circuit (2). This results in charges remaining in the cell. A shift current (Is) induced in the neighbouring cell (K) produces a data shift to this cell.

IPC: E04H7/26
Filed: 1981-04-09
Abstract: A flat silo for the ensilage of fodder comprises at least two walls, located opposite one another and laterally limiting a silage space, and a covering foil, by means of which the silage space can be covered on top. For an air-tight closure of the silage space, the two side walls are each provided in their top side with a liquid-sealing gutter, in which the covering foil can be fixed at the edge. On the end face, the silage space is limited by two end walls which are located opposite one another and which are likewise each assigned a liquid-sealing gutter for fixing the covering foil on the end face in an air-tight manner. In this way, an ensilage of fodder, especially wet grain silage, can be carried out by very simple means, with air being shut off completely from the silage space, whilst at the same time the adverse effects of odours on the environment during the fermentation process are avoided by means of the sealing gutters filled with liquid.

IPC: F16P3/02
Filed: 1981-05-16
Abstract: A circular cross-cut saw has a safety guard (5) for the rotating saw blade (2) pivotably mounted in a perpendicular plane. The safety guard (5) is closed except for the requisite working section of the saw blade (2) and is fastened to a bearing arm (6) pivotable on the machine frame (1). The working section left free by this safety guard (5) is covered by means of a guard segment (9) when the saw blade (2) is lifted out of its working position. The guard segment (9) is in turn moved about the saw-blade axis (8) under the action of a control rod (10). In order to accelerate the closing movements of the guard segment (9) and thereby increase the operating safety of the circular cross-cut saw in accordance with the regulations, the control rod (10), at its end remote from the guard segment (9), acts on an articulated lever (11) which starts from the machine frame (1) and is connected in its centre area to the bearing arm (6) of the saw blade (2) via a curved guide (12). Consequently, the desired rapid closing of the guard segment (9) is obtained when the saw blade (2) is lifted by pivoting the bearing arm (6). <IMAGE>

Abstract: A contact arrangement (1) is described which permits the automatic opening of a moving contact member (5), with a current limiting effect, in the event of high currents suddenly occurring. To this end, a lever arrangement, which comprises two bell-crank systems, is provided between the moving contact member (5) and a support (3). The first bell-crank system consists of a bent lever arm (12) of the moving contact member (5) and of a lever (14) which is a component of a further bell-crank system. The latter consists of the lever (14) which is connected to the bent lever arm (12) and of a lever (15) which is connected in a hinged manner to the support (3). A contact force spring engages on the bell-crank hinge bolt (16) of the second bell-crank system (14, 15). During dynamic contact opening, the first bell-crank system increasingly approaches the extended position, while the second bell-crank system becomes increasingly far from the extended position. In the limit position, the extended position of the first bell-crank system is exceeded and, under the influence of the contact force spring, the contact members assume a stable switched-off position with a large opening angle. The described contact arrangement is suitable for single-interrupting and double-interrupting low-voltage protection circuit breakers. <IMAGE>
