Title: Direct currents series motor for washing machines - which limits spin drying motor current to lower value than for washing
Inventor: SCHMIECHEN ARMIN
IPC: D06F37/36
Filed: 1975-04-11
Abstract: A direct-current series motor for the drive of a domestic washing machine with a slow washing speed and a high spin drying speed includes in its control circuit a unijunction transistor which is fired later to pass a current to a pulse transformer for the thyristor firing so that the motor current during the spin drying setting is limited to a lower value than during washing. In the washing setting, a smooth start control raises the motor current gently from the starting moment to its full value. The control ensures a smooth and jerk free acceleration of the washing drum and is gentle with the laundry. Little electronic appts. is required and the motor runs with a minimum of noise. The brushes have a long service life and satisfactory radio interference suppression can be achieved.

Title: Blocking castor for hospital bed - uses central shaft to operate wheel brake and pivoted ratchet brake for castor swivel
IPC: B60B33/02
Filed: 1975-05-06
Abstract: The support shaft for the castor is fitted with an internal operating shaft (17) which is moved axially by a control cam (25) at the upper end between braking and free settings. The bottom end of the shaft presses a brake pad (47) onto the outside face of the castor wheel to block it. At the same time the shaft operates on a collar (48) pivoted on a horizontal axis alongside the shaft, to move a blocking ratchet (52) into a fixed gearing (53) machined on the lower flange of the bearing support. This blocks the swivel action of the castor. The ratchet is adjustable on the collar to ensure accurate location of the ratchet and gearing. The whole assembly is designed to operate safely and with a minimum of components.

Title: Fibrous material press - has pressing rams dividing material into sections with division lines tangential to central circular hole
Inventor: STEFFENS BERT
IPC: B30B11/00
Filed: 1975-05-07
Abstract: The overall circular shape of the compacted body is divided into several sections by a corresponding number of suitably shaped check plates arranged in such a way that the division lines between the adjacent sections are positioned tangentially to a central circular hole. During the opening of the assembly the sections move relatively against each other along their adjacent division lines and form in the open position a polygonal bore with number of corners equal to the number of the pressing rams. The tangential sections around the circular hole and their centre enclose identical angles with each other. Used for compacting natural and artificial fibres, cellulose products, grasses etc. The compacted material after removal from the press retains its shape even if it increases in size.

Title: Sealing pinch bottom bags with welded seams - using tool for small scale application which makes joints isolated from contents
Inventor: THEINER FRIEDRICH
IPC: B65B51/14
Filed: 1975-05-09
Abstract: Process and appts. are claimed for welding bags across their mouths, the bags having two inner (1,2) and two outer (3,4) layers laid out so that the folding over point (K) at the top edge of one outer layer (3) can be overlapped by the two equally long inner layers (,2) to form a welded seam (14), whilst the other outer layer (4) extends beyond the inner layers, so as to form a sealing flap (5) which has a coating (6) of a material melting when heated to bond to the other outer layer (3) to enclose and reinforce the welded seam (14). According to the novelty the welding takes place under pressure with simultaneous heating, the ends of the layers (1,2) to be welded together being laid over a heating and welding blade (16) which prevents their being welded on the side of the folding line (K) turned away from the inside of the sack.

Title: Rotating frequency converter with air cooling fan - has controls in upper chamber with labyrinthine air flow path
Inventor: PILLER HANS DIPL ING
IPC: H02K9/06
Filed: 1975-06-26
Abstract: The rotating frequency converter is particularly for use in supplying power at 400 Hz derived from a normal 60 Hz supply, for computer installations. The converter is intended for use at high power levels and runs at 3000 to 3600 rpm with an audible noise level of 67 db. The sound level is minimised by the use of a fan driven ventilation system employing sound absorbent cladding in the ducting and casing. The ventilating fan is mounted on the shaft of the converter which is in a chamber below an upper chamber, the chambers being connected by an end passage. The upper chamber has control and switching units on either side of a central partition parallel to the converter shaft. At the ends of the upper chamber are vertical partitions extending upwards and downwards from the base and roof of the chamber respectively to define a labyrinthine air path to the end outlet.

Patent DE-2604369-A1 (DE)
Title: Screw connection tightening method - in which blows are given to the connection to bed down surface roughness
Inventor: HAAS NORBERT
IPC: B25B21/02
Filed: 1976-02-05
Abstract: After the screw connection has initially been tightened up, the connection settles and gradually becomes looser over a period of days or weeks. This is due to flattening of surface roughnesses in the screw threads or the parts to be connected and also to the fact tht relatively soft packings are sometimes included in the parts to be connected. Due to this settling down process, screw connections often become loose after a product has left the factory. To avoid this, blow are given to the connection in the direction of the centreline of the screw, this flattens surface roughness and avoids the bedding down with time.
Patent DE-2607777-A1 (DE)
Title: Dyed fabric steam fixing unit - with an evacuated entry chamber to prevent the ingress of air into the steam zone
Inventor: SCHIFFER GUENTER
IPC: D06B19/00

Abstract: In a process for applying a continuous steaming to textile piece goods, using saturated or superheated steam, partic. to fix dyestuffs, the fabric passes into the treatment chamber through an evacuated zone to give a press. lower than the ambient atmos. As there is no air in the treatment chamber, no time is lost by expelling unwanted air, and a more intense steaming action can be applied to the material.
