Title: Metal smelting furnace - with two interchangeable hearths on rails with rope drive
Inventor: SHARKEY LAURENCE MICHAEL
IPC: F27B3/06
Filed: 1977-11-04
Abstract: A metal smelting furnace to melt aluminium out of ferrous scrap metal consists of a furnace casing with burners and two hearths which can be moved in two positions. In one position one hearth is inside the furnace and the other is ready for removing the residue and charging outside. In the other position the two hearths reverse their location. This saves much manual work for raking the residue out of conventional hearths. The labour productivity is much improved.

Title: Programmable digital frequency divider for carrier-wave systems - produces symmetric output pulses using logic and two dividers
Inventor: SONNTAG FRITZ DIPL ING
IPC: H03K21/08
Filed: 1978-06-15
Abstract: The digital frequency divider produces symmetric pulses (duty factor = 1:1) irrespective of the denominator and is simple to program. The input is connected to an exclusive-OR gate (4) whose output feeds a programmable divider (1). The divider's output passes via a divide-by-2 divider (2) to the first input of an AND-gate (3). The AND-gate's output is connected to the second input of the exclusive-OR gate. The outputs of both dividers form outputs from the composite divider. A binary signal applied to the AND-gate's second input determines whether the denominator is odd or even.
Patent DE-2827198-A1 (DE)
Title: Steam-cracking of hydrocarbon mixts. - for prodn. of olefin(s) and synthesis gas
Inventor: VINKE ARTUR DIPL CHEM DR
IPC: C10G9/00
Filed: 1978-06-21
Abstract: Hydrocarbons in the propane to 360 degrees C ranges are cracked by spraying through one or pref. several nozzles into superheated steam to produce a homogeneous mixt. across the whole reactor section, in which thermal cracking, gasification and quenching occur in parallel. Compsn. of the product is determined by the feed compsn., temp. of the steam or steam/oxygen mixt., oxygen content of the mixt. and quantity of feed. For prodb. of lower unsatd. hydrocarbons above, the feed is sprayed into steam at 900-1600 degrees (1100-1400 degrees)C, while for simultaneous prodn. of synthesis gas, it is sprayed into a mixt. of steam and O2 and/or air at 900-1600 degrees (1000-1400 degrees)C. Quenching by a drop in temp. of 600-750 degrees C, due to endothermic vaporisation and cracking of the hydrocarbons occurs simultaneously with cracking, ensuring that the product compsn. at the high cracking temp. is frozen in. By homogeneous mixing, the oxygen present does not react directly with the hydrocarbon or hydrogen formed by cracking, but catalyses the cracking process, and by reacting with carbon gives higher H/C ratio in the product.
Patent DE-2842836-A1 (DE)
Title: Dialysis membrane comprising hollow cellulose fibre - with improved exchange surface in wavy form, mfd. from cuprammonium soln. of cellulose
Inventor: HENNE WERNER DIPL CHEM DR
IPC: A61M1/16
Filed: 1978-10-02
Abstract: A dialysis membrane of cellulose regenerated from cuprammonium solns. is in the form of a hollow fibre with a continuous empty space. The fibre surface shows periodic variations in the longitudinal direction (e.g. comprising longitudinal waves) and/or in the peripheral direction. Thus the cross-section, perpendicular to the fibre axis, varies periodically over the fibre length. The membrane can be mfd. by extrusion of a cuprammonium soln. of cellulose into an aq. caustic soda soln. through the annular slit of a hollow fibre die immersed in the aq. caustic soda soln. A liq. which will shape the empty space is extruded through the inner passage of the die. The ratio of the speed of drawing of the hollow fibre over the first drawing roller to the speed of extrusion of the cuprammonium soln. of cellulose from the annular slit is 1-1.05. The direction the fibre follows from the die to the first drawing roller forms an acute angle, pref. 15-70 degrees, with the axis of the die apertures. Subsequent treatment of the fibre is as usual. The membrane is used partic. in haemodialysis. The efficiency of dialysis is increased owing to an improved exchange surface.

Title: Pressure die casting or injection moulding machine - where reciprocating gripper removes casting or moulding residues and also lubricates dies
Inventor: DOBE WILFRIED ING GRAD
IPC: B22D17/20
Filed: 1978-12-27
Abstract: After casting or moulding, the upper piston(13) on the machine is raised and a ring gripper(11) is moved transversely onto the die axis. The lower piston(17) in the machine is then driven upwards to force the casting or moulding residue into gripper(11), which is then retracted so the residue(16) falls via a chute into a scrap bin(20). The reciprocation of gripper(11) is pref. synchronised with the movement of the upper and lower pistons in the machine; and the gripper pref. contains a ring nozzle feeding grease onto the lower piston each time the gripper is driven into the machine. Automatic removal of casting residue is combined with automatic lubrication of the casting or moulding machine.

Title: Synchromesh mechanism for vehicle gearbox - uses shortened mesh teeth on synchro ring in comparison to drive wheel
Inventor: TAKAHASHI KOTAI
IPC: F16D23/06
Filed: 1979-02-21
Abstract: The compat layout of the synchromesh in the gearbox has the synchro ring (42) fitted with clutch grooves shorter than the corresponding grooves on the drive wheel (20). The synchro travel is much reduced and results in a shorter transmission. The synchro travel is shorter and more positive, with less danger of slipping between gears. A quieter gearchange is also obtained.

Title: Phase controlled thyristor triggering circuit - reduces bulk by eliminating isolating transformer whilst keeping galvanic isolation between control element and thyristor power circuit
Inventor: LOB UDO DIPL ING
IPC: H02M1/08
Filed: 1979-04-04
Abstract: The circuit is for the phase control of a thyristor (2) or triac in series with a load (1) connected across an a.c. single phase power supply. The circuit reduces the bulk of the triggering circuit by eliminating an isolating transformer whilst maintaining galvanic isolation between the control element and the thyristor power circuit. A d.c. supply is derived from the single phase mains by means of a rectifier (7). This supply is connected across a switching transistor (9) and an auxiliary thyristor (8). An optically controlled transistor (10) provides the link with the control element setting the required trigger delay for the main thyristor (2). With no light signal, the switching transistor (9) conducts and there is no signal to the auxiliary thyristor (8) gate. A light signal brings the opto-transistor (10) into conduction turning off the switching transistor (9). A trigger voltage is then available to the auxiliary thyristor (8) and is turned on, triggering the main thyristor (2).

Title: Heat shrink sleeving sealing for cables - utilises shaped interlocking forms in longitudinal edges of sleeving
Inventor: MUELLER SIEGFRIED
IPC: B29C61/10
Filed: 1979-07-11
Abstract: The heat shrink sleeve is for cables or tubes and is wrapped around at the ends which are fixed together by C-shaped forms in the sleeve which interlock. An inner support overcomes difficulties of assembly of earlier methods and provides good retention of the longitudinal edges. A heat shrink sleeve (1a) has C-shaped swellings (4a, 5a) towards the exterior and close to both the longitudinal edges (2a, 3a). The thickness of material is constant including the area of the swellings. A reinforcing strip (7a) is inserted into the smaller swelling. This contains a wire (7c) which allows the material to give good resistance to compression. The smaller swelling is inserted into the larger when the sleeving is wrapped around the sleeved object. An inner section (7b) of the reinforcing strip is surrounded in glue (17) to provide sealing when heat is applied. The combined swellings are compressed by a C-shaped rail (6a).
