Title: On-site fittable telecommunication cable mountings - flexible mounting by a clip and tongue arrangement
Inventor: FORBERG HORST
IPC: H02G15/02
Filed: 1972-07-19
Abstract: The cable sockets allow for adjustment of the socket union and thereby of the cable axis to be decided at the installation site. The difficulties associated with the fitting of several mountings into little space are reduced and the contacting of the cable screening improved during the introduction of cables with layered mantles. The cable socket is clamped onto the cable by a jubilee clip. The mounting consists at the clamping site of several longish tongues and carries cross ribs to fix the clip and to fix the posn of the cable. The mounting is provied with a fixing flange forming a single unit with the tongues. A cable screening contacting device is provided, which automatically adjusts itself to the cable axis and is formly connected to the jousing of the mounting. The device consists of a support ring and two clip like half rings. Two fixing flaps are connected to each half ring of such dimensions, that their twisting due to a movement of the cable caused by a turning of the cable socket mounting makes them cover the cable axis and the axis of the contacting device. This is achieved by having the apex of the angle through which the cable can move lysing in the centre axis of the opposite fixing flap. The cable mounting is pref. made from a tension-free workable thermoplastic e.g. cellulose acetate.

Title: Forklift truck safety device - has load measuring device in tilting mechanism stopping truck travelling
Inventor: TAAKE MANFRED
IPC: B66F17/00
Filed: 1974-01-04
Abstract: The device is for use with a truck having a tilting mast, and in the parts of the tilting mechanism affected by the load, a measuring device, is fitted. In the event of overloading, or the centre of gravity of the load being too far forward, this switches off the truck travel motion. The measuring device can be connected to a signal amplifier and a limit switch, which transmit the signals received to a solenoid valve controlling the travel motion. The mast tilting ram can have a measuring chamber separate from its main one, in which a measuring device, typically a bellows-type diaphragm connected to the ram mounting on the truck chassis is accommodated.
Patent DE-2404884-A1 (DE)
Title: Spacing control between vehicles in column - error signal introduces acceleration or retardation for predetermined period
Inventor: RAHN WOLF DIPL ING
IPC: B60K31/16
Filed: 1974-02-01
Abstract: The control of relative position between vehicles moving in a column is effected by comparing actual position with a predetermined reference value. A controller provides a reference input for the comparator stage of a regulator. If the comparator generates a difference output that exceeds a predetermined value, a filter ensures that a correcting signal is generated. The correcting signal is generated by adding in either an accelerating or retarding signal for a predetermined time duration. In this way the actual position is adjusted to the ideal reference values. Other vehicles can join the regulated column. This is easily accommodated since the spacing between vehicles can safely be reduced to a minimum.
Patent DE-2406922-A1 (DE)
Title: Voltage monitor for emergency supply - has monitoring relay switched, during AC failure from main- and sub-batteries to main
Inventor: STEIN HANS-GUENTHER DIPL ING
IPC: H02J9/06
Filed: 1974-02-14
Abstract: The voltage monitor, for emergency power supply systems, has its voltage-monitoring relay switched from the main and sub-batteries to the main battery when the a.c. supply fails and switched back again to the main and sub-batteries when the a.c. supply returns. All the batteries are connected over DC/AC converters to the a.c. supply. This manner of switching the relay keeps the maximum change in the load voltage during switch over as low as possible, i.e. keeps its change smaller than the voltage swing between the batteries' lowest discharge voltage and the constant charging voltage. In a further embodiment a protective resistance is provide for each opposed contact of the switching relay to limit the current in the event of a short circuit.

Title: Washing machine spin-drying process - has an intermediate water introduction phase to loosen clothing from drum mantle
Inventor: BLANK MANFRED
IPC: D06F35/00
Filed: 1974-04-03
Abstract: In a washing machine, with a horizontal drum, the spin-drying phase is interrupted after 100-200 seconds, and when the drum is at rest it is filled with water until the lower sector of the clothing clinging to the drum mantle is awash. When the water has been pumped out, the clothing is loosened by intermittent drum rotation at washing speeds, followed by rotation at spin-drying speeds for a further 200-300 seconds. The process gives a short drying time with the clothing loosened and dry.

Title: Blanking parts from cold-rolled steel strip - using electron beam for local heating of the contour to assist blanking
Inventor: BECK GUENTER DR ING
IPC: B21D28/00
Filed: 1974-04-23
Abstract: The continuous strip is heated to below the m. pt. by an adjustable beam of energy in prescribed zones, and the resulting structural boundaries are used to trigger the subsequent blanking or sepn. process. The strength of the steel is pref. reduced by heating to below Ac1 along the entire contour of the part being made, followed by punching-out or precision blanking along the weakend contour. The steel may also be heated in prescribed zones to form austenite followed by controlled local cooling and blanking so that the part contains prescribed hardened zones along selected regions of the contour. Used for the blanking of a very wide variety of parts, e.g. for office machines. The localised softening of the contour being blanked results in longer tool life, in addn. the contour of the blanked part may be locally hardened.

Title: Theftproof display box esp for music cassettes - has open top and bottom and surrounding walls with lips
Inventor: DOEBELI HEINZ W
IPC: B65D73/00
Filed: 1974-05-29
Abstract: A frame for a box-shaped object comprises a base plate with a holder surrounding the object in the form of walls standing up from the base plate and having suitable clearance between them to permit easy insertion of the object; mutually facing walls have, at their top edges, inwardly projecting webs which reach just sufficiently far inwards to bridge the clearance of the object from the walls and prevent it from being removed. In a preferred arrangement, where the object to be contained is rectangular, the walls constitute a box open at the top and bottom, with the base plate projecting outwards, esp. with recesses of general trapezium shape in the centre of each side so that the full width and length of the base plate occurs only at the corners. It is used for display of music cassettes and similar articles in a shop. The frame is sufficiently large to prevent shop lifters from removing it without being seen.
