Patent DE-2403076-A1 (DE)
Title: Heat consumption meter - for heating costs distribution, compares individual installation heat consumption with total consumption
Inventor: LOEWENHOFF PETER DIPL ING
IPC: H03M1/00
Filed: 1974-01-23
Abstract: Analogue electrical signals corresponding to heat consumption of individual consumers, are compared with the output signal of a digital-analogue converter common to all consumers, pulses from a common pulse generator are allowed to pass or are prevented from passing to pulse counters in each apartment, depending on which of the signals is the greater. The digital-analogue converter is controlled by an electronic counting circuit, in which the counting sequence is continuously repeated; for larger apartment blocks, or whole city districts the digital-analogue converter and/or the pulse generator output signals are amplified, in order to be able to cope with a greater number of meters.

Title: Easily manipullable necklace clasp with eyelet - has incomplete annular body adjoining decorative cover and resiliently movable to receive eyelet
Inventor: BURKHARDT ALFRED
IPC: A44C11/02
Filed: 1974-03-11
Abstract: The necklace clasp is designed with an eyelet or the like attached to the two ends of the necklace or the like which are to be placed on an annular body which has at least one break and is firmly connected on one side of this break to the covering decorative element. On the other side of this break the annular body abuts resiliently and radially outwards against a support member which is also firmly connected to the covering decorative element.

Title: Redundancy-type protective switch - has dummy cct. switched in by failure current magnetic field which shorts supply lines
Inventor: LAUERER FRIEDRICH DIPL ING
IPC: H02H3/33
Filed: 1974-05-24
Abstract: The redundancy-type protective switch has a means of switching in an additional artificial failure current (circuit in response to the magnetic field produced by a failure current, e.g. an earth or short circuit current. The artificial circuit affects the sum current transformer or the cut-out element, and/or short circuits the supply lines in front of the protective switch contacts. The artificial failure current and/or the short circuit current are preferably delayed before they become effective. The artificial failure current may assume a value that leads to the cutting-out of an overload protection element, connected in series. The time dependent increase in the artificial failure current may be provided by negative temperature coefficient resistor.

Title: Hydraulic brake system for bicycles - has separate circuits for forward and rear brakes with simultaneous operating system
Inventor: WILLIAMS LYNN A
IPC: B62L1/16
Filed: 1974-12-05
Abstract: The brake operating mechanism exerts greater force on the front wheels than the rear wheels, the proportion being between 52:48 and 70:30, typically 55:45. The brakes are side operated and in each hydraulic circuit there is a hydraulic intensifier. This is operated by an adjustable pressure plate acted on by the pivoted hand lever.

Title: Strip material shredding machine - of which the cutting rotor is stopped when feeding funnel and cutter insert are removed
Inventor: FREY ROLAND
IPC: B02C18/14
Filed: 1974-12-20
Abstract: The shredding machine consists of a housing, a cutter insert which can be removed from the housing, a cutter rotor, a roller which feeds the material to be cut to the rotor and a gear drive for roller and rotor. The filling funnel for the cutter forms, when it is in its working position, a stop for the cutter insert. When the funnel is removed, the cutter insert can be removed. The coupling which drives the rotor, mounted inside the cutter insert, is disengaged when the cutter insert is removed. The operator is therefore safeguarded against being cut by the rotor. The rotor coupling is in the form of a pin which engages with a V shaped slot in the driving part.

Title: Bending and tensioning of concrete prestress components - uses belt stressing member in tubular socket over pulley-type arches
Inventor: SCHLEICH JOSEF DIPL ING
IPC: E04C5/08
Filed: 1975-04-26
Abstract: The process, used in work with steel-reinforced concrete, is for the prestressing of site-concrete or prefabricated structural components, for exerting pressure on the cross-sectional areas subjected to tension. The stress member runs like a belt, from prestressing anchorage to terminal anchorage, in tubular sleeve sockets for subsequent pressing out. It is then deflected over the back of an arch, like a band pulley, and runs back again, to meet the end of the stress member in a band pulley configuration, and here the closed linkage for pre-stressing anchorage is produced. The prestressing process is reliable, simple and economical.
