Patent DE-2346617-A1 (DE)
Inventor: EICHELBERGER EDWARD BAXTER
IPC: G06F9/40
Filed: 1973-09-15
Abstract: Propagation delay testing is performed on a generalized and modular logic system that is utilized as an arithmetic/logical unit in a digital computer. Each arithmetic/logical unit of a computer is formed of arrangements of combinational logic networks and storage circuitry. The storage circuitry has the capability for performing scan-in/scan-out operations independently of the system input/output and controls. Using this scan capability, the method of the invention provides for the state of the storage circuitry to be preconditioned and independent of its prior history. Selected propagation paths through the system circuitry are sensitized by test patterns from an automatic test generator. By altering selected inputs and cycling controls applied to the networks of combinational logic and their respective associated storage circuitry, propagation delay indications through the selected paths are obtained to determine the status of these path delays through the logic system.

Patent DE-2427727-A1 (DE)
Title: Bedpan- and urine-bottle-rinsing appts. - uses single overall timer and automatically turned mixer valve
Inventor: MONES HARRY
IPC: A61G9/02
Filed: 1974-06-08
Abstract: The mixer valve supplies water to the rnsing nozzles for a period determined by the timer, which is of a conventional kind. A branch from the main flow takes part of the rinsing water through a throttle valve into a cylinder where it causes a piston to rise slowly against the pressure of a spring. The piston, in rising, turns the mixer valve to change the rinsing water from cold, through warm, to hot, and finally operates a valve to complete the rinse with a dash of disinfectant. The timer now shuts off the water supply from the mixer, thus allowing the control cylinder to empty itself and return the apparatus to its initial status.

Title: Noise-reducing screening in vibration mills - has sound-absorbing material applied right at the source of the noise
Inventor: HAUDE FRIEDHELM
IPC: B02C17/14
Filed: 1974-08-14
Abstract: In a vibration mill, the material to be treated is placed in an elastically-mounted horizontal tube, which is then vibrated. It is the vibration that produces the milling effect, as well as, often, more noise than is legally permissible. Sound-insulation methods which involve encapsulating the entire machine are rejected in favour of applying sound-absorbing steel-plastic or steel-plastic-steel laminated sheets (outside any thermal-insulation sheathing) directly to the vibrating horizontal tubes themselves, and thus confining the sound at its source. A mill tube (14, with lining 15) is sheathed with a sound-absorbing layer (23'), then with a thermal insulator (e.g. foamed polyurethane), then a further sound-absorbing layer (23). The polyurethane is replaced by a firmer material (16, in several different designs) wherever mounting clamps (3) are fastened round the tube.

Patent DE-2444066-A1 (DE)
Title: Coke from poorly coking coal - by agglomeration of fine coal with binder before normal coking
Inventor: WENZEL WERNER PROF DR ING
IPC: C10B53/08
Filed: 1974-09-14
Abstract: Coke with good mechanical properties is produced from coal of poor coking quality by (a) agglomerating the finely divided coal at 80-100 degrees C with a binder selected from heavy oils, tars and other high-boiling hydrocarbons to form pellets contg. 5-30 (pref. 20-25) wt.% binder, and (b) coking the pellets by standard methods, esp. in by-product ovens. The uncoked pellets can be stored and transported without breaking, and can be coked by conventional methods to produce lump coke with better cohesion and abrasion resistance than coke produced from the coal alone. Short coking times can be employed. Agglutination of the pellets during coking can be prevented by means of spacer layers (thickness 0.2-2, pref. 0.5 mm) of a finely divided material such as haematite, lime (which also acts as a desulphurizer) or coke dust. Instead of the coal/binder pellets other coal/oil agglomerates, e.g. coal briquettes with an oil binder, can be used. During coking, the heating can be accelerated by blowing hot gas (pref. coke oven gas) through the voids between the pellets from openings in the bottom part of the oven. The oil or tar recovered as byproduct can be recycled as binder, pref. after adding a cracking catalyst (e.g. AlCl3 or bentonite).

Patent DE-2515557-A1 (DE)
Title: Matrix printer with variable letter width - controlling use of gaps between matrix points varies width
Inventor: BABSCH ALFRED
IPC: B41J2/505
Filed: 1975-04-09
Abstract: Thematrix printer, which can, for example, use printing wires forming a 9 by 9 matrix, is able to print symbols whose width is varied at will. In an example the symbol N can be stored in a fixed value store (symbol generator) and printed with a gap between the vertical limbs and the diagonal part of the symbol. In a narrower form the symbol can be printed without these gaps so that the two limbs are closer together. This is achieved by using a gap program and a back-coupled register at the output to the symbol generator. When a broader version of the symbol is to be printed, the symbol is recalled from the symbol generator through the gap program.
Patent DE-2520465-A1 (DE)
Title: Electronic control for air conditioning systems - gives variable room temp. dependent on solar radiation and shade temp.
Inventor: HANSEN HERBERT
IPC: G05D23/24
Filed: 1975-05-07
Abstract: Below a preset value (U3) of shade temp. the control operates in one mode and switches to another mode above this temp. The desired value of room temp. is a linear function of the outdoor shade temp. with a positive slope in the lower range and a negative slope in the upper range. Both these characteristics are displaced parallel to themselves by changes in the difference (delta U) between the solar radiation and outdoor shade temps. Thus with rising outdoor shade temp. the room temp. is allowed to rise. This is consistent with comfort requirements and considerations of economy. In both operating ranges an increase in solar radiation for a given shade temp. increases the cooling.

Patent DE-2540847-A1 (DE)
Title: High speed hovercraft with extra lift - uses flaps to divert thrust from forward engine to under craft
Inventor: FISCHER HANS-OTTO
IPC: B60V1/22
Filed: 1975-09-13
Abstract: The high speed hovercraft has a shaped wing (1) to trap an air cushion between it and the ground as the craft is moved rapidly forwards by an impeller engine (3). To generate improved lift from the air cushion, flaps (13, 14) in the wing and behind the engine divert some of the thrust to the cushion. This enables the craft to ride over obstructions, without any complicated skirts. Pivoted flaps (8) under the leading edges of the wings limit the forward extension of the air cushion and enable a high pressure cushion to be used at low speeds. The flaps swing open as the static pressure builds up on fast forward flight.
