Title: Weaving frame - of light construction for hand weaving - with reed and hand-operated shuttle
Inventor: WILKE ELISABETH
IPC: D03D29/00
Filed: 1970-05-02
Abstract: The hand weaving frame consists of side pieces with extension to carry a roller and a serrated component to make up the frame and stretch the warp yarns.

Title: Trifluoroacetaldehyde isolation - from mixts with hf where in form of hf adduct by hemiacetal formation
Inventor: SIEGEMUNG GUENTER DR
IPC: C07C43/30
Filed: 1971-08-05
Abstract: The mixts., obtd. by chloral fluorination, and contg. CF3CHO.HF and HCl are reacted with Si(OR)4 or ROH and SiCl4 to form the hemiacetal of formula:- CF3CH(OH)OR (where R is 1-5C alkyl). The HCl and SiF4 formed are driven off by heating or inert gas and the hermiacetal recovered by fractional distillation. It is a convenient storage stable and transportable form of the aldehyde which is converted to the free aldehyde by reaction with H2SO4 or polyphosphoric acid.

Title: Tensioner for horizontal belt saw - has blade prestressed by spring applying force through wedge when handwheel is released
Inventor: SATO MASAO
IPC: B23D55/00
Filed: 1971-06-16
Abstract: The saw belt tensioner uses the combined functions of the pre-stress of a spring and a lifting - and wedge assembly. To tension the saw belt a trigger is pulled and the catch lifted off so that the lever snaps back into the starting position. By turning a handwheel anti-clockwise a carriage moves so that the centre of driving and driven discs are nearer to each other and the belt fitting is facilitated. When the handwheel is turned clockwise, the carriage moves in the opposite direction, the belt is tensioned and the reaction of the tensional force pulls the shaft and a tapered ring in the same direction.

Title: Continuous forming machine - with adiabatic expansion of the thermoplastic material
Inventor: HOSHI HIROSHI
IPC: B29C44/30
Filed: 1972-08-28
Abstract: Freshly produced synthetic resin contg. foaming agent passes into the machine which consists of two endless steel bands, whose gap narrows from the inlet towards the outlet end. Between the bands is a tapered heated chest. The resin is conveyed into the chest, so tht it is gradually compressed whilst the temperature rise and foaming proceeds. As the material emerges at the outlet of the chest, its pressure is suddenly released and adiabatic expansion takes place.

Title: Centrifugally cast hollow spheres - by mixing concrete or concrete/plastic in mould at low rotational velocity, and casting at higher velocity
Inventor: HAASE HARRY
IPC: B28B1/20
Filed: 1972-07-01
Abstract: Large dia. hollow spheres e.g. for use as storage vessels, are produced by centrifugal casting by (a) introducing into a spherical mould a moulding material based on concrete or a concrete-plastic mixt. e.g. a polyester mixt, without mixing, in a total amt. suitable for the mfr. of the sphere, (b) mixing by rotating the mould around 2 axes at a first low velocity, and (c) considerably increasing the velocity of rotation of the mould around each axis to obtain the centrifugal velocity, at which the mixt. is spread uniformly over the inner wall of the mould. Wall strength of the sphere can be controlled by varying the velocity of rotation.

Title: Flame cutting non-conducting materials - using direct current arc with current flowing in outer casing of torch
Inventor: KOSFELD GERHARD DR ING
IPC: B23K35/02
Filed: 1973-05-29
Abstract: The novel feature is that the arc is formed between the core-wire and the outer jacket of the torch, i.e. the complete torch is consumable, and can be used to cut brick, tiles, granite, armoured glass, ceramics. The torch consists of an outer steel jacket 0.5-4, pref. 1 mm thick surrounding an insulating filler, 4-20, pref. 8 mm dia. and a central core-wire 2-10, pref. 4 mm dia. The core wire is connected to the negative pole, and the outer jacket to the positive pole of a D.C. source. The insulating filler should contain organic materials, e.g. cellulose or sawdust for gas generation when the torch is working. The arc can be struck by dipping the end of the torch into iron powder and the torch can be used until both the core-wire and jacket have burned down to the arm used on the outside dia. for electric connection.

Title: Overhead transport system with variable speed motor - uses electric motor with vertical axis hung below channel shaped rails driving through gearbox
Inventor: UTTSCHEID GEORG
IPC: B61C13/04
Filed: 1973-07-06
Abstract: The electric motor is fitted with a flange and the gearbox is coupled to a worm and worm wheel output drive. The wormwheel is supported by an axle and rollers running in a double U channel rail system. Hanging from the motor-gearbox is the load carrying member.

Title: Hydraulically regulated nozzle for an injection moulding machine - opening and closing precisely, held closed mechanically during changeover
Inventor: HEHL KARL LOUEBURG
IPC: B29C45/23
Filed: 1973-07-16
Abstract: The needle valve stem of a nozzle for a plastic injection moulder, is operated, opening and closing the outlet to the mould, by a toothed lever pivoting in a recess of the nozzle body, and meshing with a rack on the valve stem. Lever is moved by the rod of a hydraulic piston. This is fed in common with the piston of the hydraulic device for injecting the plastic material into the mould, from the same pressure source. The forward sides of both cylinders are thus loaded together and the nozzle opens when pressure has built up in the injection line. Similarly, the annulus side of the hydraulic piston is fed in common with the pressure side of the hydraulic circuit for the motor turning the plasticising screw. When the spool on the control valve connects pressure feed to line the nozzle is closed and the screw rotates. A spring presses on the piston and keeps the nozzle closed. Simple and cheap design. Nozzle opens and closes with precise timing. Can if necessary be converted from a hydraulic to a spring-loaded mechanical operation.
Patent DE-2342904-A1 (DE)
Title: Directional aerial with small side lobes - removes masking influence on attenuation by widening aperture to transition zone
Inventor: REBHAN WOLFGANG DIPL-ING
IPC: H01Q19/19
Filed: 1973-08-24
Abstract: The directional aerial is used for propagation of very short electromagnetic waves such as in space satellite tracking systems. It has polar diagrams with suppressed side lobes. Initially the attenuation of the side lobe fields are unfavourably influenced by the masking by the aerial aperture. The shadow borders which include the outer edges of the aerial aperture are now expanded into transition zones. Within these zones the distribution in the direction of the shadow drops off to an approximately flat curve. The width of the transition zone will increase as the shadow zone increases, cancelling its effect to produce uninterrupted distribution.

Title: Rolling strip to close tolerances - using continuous measurement of both roll pressure and strip thickness to adjust gap
Inventor: NAGEL WERNER
IPC: B21B37/64
Filed: 1973-10-27
Abstract: The process and device are for the continuous control of the thickness of a rolled prod. by (in)direct alteration of the roll gap, where the pressure on the rolls is continuously measured and adjusted so a constant gap dimension is maintained. The roll pressure pref. generates a proportional electronic signal which is used to correct the gap and compensation is made for alteration in the width of the prod. It is also pref. to measure the thickness of the rolled prod. and to use separate electronic signals to correct any variation from the desired value. The pref. rolling mill uses hydraulic gap-adjusting cylinders fed by servo-valves using a servoamplifier. Provides very rapid response of hydraulic circuit so very close dimensional tolerances can be obtd.
