Title: Low pressure preliminary dewatering of bagasse - with multiple rearrangement of fibre layers and uninterrupted pressure cylinder working
Inventor: KAETHER WILLY
IPC: C13B15/00
Filed: 1978-05-05
Abstract: In a process for reducing the moisture content of bagasse, the cane is treated by passage through a diffuser followed by dewatering mills working at high pressure. The sugar content is washed out in the extrn. zone of the diffuser by spraying with extn. fluid in countercurrent. At the outlet of the diffuser, the cane is subjected to a preliminary dewatering operation by large dia. cylinders exerting low pressure. During the uninterruptedly progressing pressing operation, the bagasse layers are subjected to multiple displacement and rearrangement, and it is fed through differently constituted, successive, interrupted pressing zones. As distinct from the preceding flat pressing and screening surface, the following screening surface is a curved one, and the originally flat package of bagasse in the flat pressing zone, has imparted to it, a curved form, under the influence of the curvature of the low pressure cylinder. The interrupted transition zone between the flat and the curved pressing zones, is positioned where the highest degree of longitudinal thrust of the package of bagasse deformed by the low pressure preliminary dewatering cylinder occurs. Improvement relates to special measure and their use in combination so as to ensure an uninterrupted, and smooth transition of the mass of bagasse, from the flat to the curved pressing zone, and to make possible an additional dewatering in the transition zone. The special measures are required in the zone at the ends of the chains where there is no screen. They consist on the special corm of the start of the curved pressing zone; the positioning of the transition zone relatively to the low pressure cylinder and its height relatively to the flat pressing zone.

Title: Spent nuclear fuel caskets - with releasable clamping lugs for remote control of lid raising
Inventor: DANNEHL GUENTHER ING GRAD
IPC: G21F5/12
Filed: 1978-09-11
Abstract: Casket has a lid which is fixed by screws to the top flange of the container. On arrival at the depository, a six-armed spider is applied to the top, with clamping lugs underneath the flange.

Title: Analogue voltage or current comparison transformer - has core with sharp transition from linear to saturated condition
Inventor: KRAUS PETER DIPL ING
IPC: G01R19/20
Filed: 1978-11-25
Abstract: A circuit for comparing analogue electrical voltage or current signals is applicable to monitoring devices in transportation, reactor technology, or air and space travel. It delivers a signal when one or more of its components fails which enables the integrity of the monitored system to be maintained. The signals (S1, S2) being compared are delivered to coils (W3, W4) of a transformer (2) with a core (3). When the signals have the demand values the coils induce opposite polarity mutually cancelling magnetic fluxes in the core. The transformer is also subjected to periodically alternating magnetisation whose magnitude determines the permissible deviation of the compared signals. It has an output coil (W2) connected to a switching stage (6). The hysteresis curve of the core material has highly linear edges and a sharp transition into saturation.

Title: Reusable cable junction box - with adhesive fusible strips joining split cylinder and caps to cylinder
Inventor: KUNZE DIETER DIPL ING
IPC: B29C61/10
Filed: 1979-09-18
Abstract: A cable junction box consists of a split cylinder and two caps with the cable seals, both made of a heat shrinking plastic. The cylinder slit ends overlap and are sealed by a fusible adhesive strip. Rings of the same strip near the cylinder ends seal the two caps. To complete the seal, mechanical clamps are applied and the strip zones are heated to the adhesive fusion temperature which is below the shrinking temperature. If the junction box has to be opened, these zones are heated enough to fuse the adhesive so that the junction box can be used many times, replacing only the adhesive. The cylinder can be made of perfluoroethylene propylene or of an elastomer such as ethylene-propylene-diene or flurorubber.

Title: Gasification fuel produced from coal dust - by mixing oversize with pelletised undersize contg. much dust
Inventor: RICHTER ARTUR
IPC: C10L5/04
Filed: 1980-01-05
Abstract: Fuel for the gasification under pressure in a fixed bed gasifier is produced from smalls which are classified into an oversize fraction of 2-9 mm and an undersize fraction of 0-2mm. The latter is pelletised by the addn. of sulphite liquor and hardened, at least on the surface, before pellets and oversize fraction are merged on the fixed bed. Before the pelletizing operation, fines of under 0.1 mm are added in considerable quantity, e.g. 35%; the fines may be derived from aspirated dust and may be supplemented by filter sherry. This reduces the consumption of binder and produces high-quality pellets in spite of this.

Abstract: The mortars are used for walls or facings, and may be transported via lorries etc. The binder consists of portland cement, blast furnace cement, iron portland cement, special cement, PM- binder, and/or CaO. Various additives are pref. added during or after mfr. of the binder. In the prior art mortars with long setting times are made by mixing binders, sand, water, and addns., e.g. retardants; but the wt. of the addns. is often inaccurate, and sometimes the wrong addns. are employed. These problems are avoided by mfg. a binder which already contains the desired addns., which may include water retention agents and polymers.
Patent DE-3000960-A1 (DE)
Inventor: ECKERT KONRAD DIPL ING DR
IPC: F02M59/26
Filed: 1980-01-12
Abstract: A fuel injection apparatus for internal combustion engines, in which the onset and end of injection are determined by a hydraulically actuated control slide. The injection pump of the apparatus, which is preferably combined with an injection nozzle to form a pump/nozzle unit, has a pump piston embodied as a differential piston, whose section having the larger diameter serves as an auxiliary pump piston and generates a control pressure (pS) actuating the control slide. During its compression stroke the control slide, in order to initiate the onset of injection, closes an overflow line leading out of the pump work chamber; and during its return stroke, which is effected by the pressure drop in the control line, the control slide relieves the overflow line in order to control the end of injection. The control pressure (pS) in the control line necessary for actuating the stroke movement of the control slide is controlled by the closure of this line by means of a control device and is built up during the compression stroke of the auxiliary pump piston.

Title: Plug-type pipe union - has catch lever with leaf spring on sliding sleeve engaging in peripheral recess
Inventor: NECKERMANN WALTER
IPC: F16L37/50
Filed: 1980-01-21
Abstract: The plug-type union is for the quick connection of a pipe end to a sealing cap or other component. It has a radial spring clamping catch locked by an axial spring on one end, engaging in a locking recess in the other. The locking recess (4) is formed in the periphery of the pipe end or a sleeve fitting round it (1,3), while the catch is a lever (13) with a leaf spring (14) rocking on a sliding sleeve (12) fitting over the cap etc and spring-loaded (8) in the axial direction away from a stop (9) on the latter. This causes the catch when engaged in the recess to press against a stop in the latter, and exerts a set pressure on the sealing faces (5,7) via a joint ring (6).

Title: Ribbon transporter mechanism tensioner - has loop-type spring in frictional contact with enclosed spool hub
Inventor: HANENKAMP HORST
IPC: B41J35/08
Filed: 1980-02-02
Abstract: The belt transporter mechanism tensioner is particularly for a typewriter eraser ribbon. It has a spring acting via a friction brake on a storage spool turning about a fixed axis, so as to exert a force opposing that indexing the ribbon from the spool. The loop-type spring encloses and is in friction contact with a hub supporting the spool (9), which pulls it as it turns until the free end (27) of its arm (37) encounters a stop (39) fixed to the frame. A further spring (29), under tension, extends between the other end (25) of the first spring and the anchor point (33) in the mounting (1), and is placed under further tension as the ribbon is pulled off, exerting in the process a torque in the opposite direction so as to keep the ribbon taut (11).
