Patent DE-3017099-A1 (DE)
Title: Crash helmet with fastening groove - which is open on inner helmet side with closed ends, and has padding with bead at outer edge
Inventor: ZAHN CHRISTIAN
IPC: A42B3/12
Filed: 1980-05-03
Abstract: The slip-on crash helmet has a fastening part around its edge for detachably holding a padded part. The fastening part is formed as a groove which opens radially from the inner side of the helmet, but is closed at the ends by the side walls. The padded part has a resiliently deformable reinforcement attached to the curved outer edge so that it fits into the groove under tension. Since the groove opens inwards and not upwards the closing end side walls prevent the padded part from moving and slipping out of the groove, thus ensuring secure fastening.

Title: Roof safety anchor without cold bridge - has heat insulating tubular shaft filling and sheath, with anchor plate underlay
Inventor: KORFF HANS-KLAUS
IPC: E04G21/32
Filed: 1980-06-12
Abstract: The bottom of a metal shaft is fastened to a protruding metal anchor plate and its open end forms a head for detachable connection of a separate attachment device. The shaft is a tube (1), with a filling (8) and sheath (4) of heat-insulating material. The connecting head has a thread (7) for screwing on a threaded attachment device. There is a heat-insulating underlay panel (3) on the bottom of the anchor plate (2). The sheath is enclosed in a weatherproof sleeve (5), fastened to a protruding tube end section, and forming a laterally protruding collar (11) at an interval from the plate. This prevents formation of a cold bridge to the flat roof concrete.

Title: Monitoring condition of burner system - uses control system which indicates which of several detectors has operated first
Inventor: CADE PHILLIP J
IPC: F23N5/20
Filed: 1980-08-14
Abstract: The condition of a furnace burner is monitored by a number of detectors. The problem of deciding which detector was operated first is overcome by an electronic control circuit. This inhibits indication of an abnormal condition for a predetermined period after starting to allow operational values to be attained to eliminate parasitic effects. A control circuit (16) monitors a series circuit of interlocks (30) and also the pilot and main fuel flows. Each monitoring circuit (34) comprises a current limiting resistor (36) in series with a luminous source of an optical coupler (38). Associated indicator circuits (18,19) each containing an LED (15) remain lit to indicate cause of stoppage of the burner. These circuits respond to signals from a control circuit.
Patent DE-3031036-A1 (DE)
Title: Thermally insulating panel to underfloor heating - has edge laps coated with adhesive to bond to adjacent panel
Inventor: DREIER JUERGEN
IPC: E04F15/18
Filed: 1980-08-16
Abstract: A thermally insulating tile or slab is intended for underfloor heating systems, to be laid over the structural (concrete) floor, the pipes being then laid on the thermally insulating panel and embedded in the floor finishing layer. Each panel consists of upper and lower plates of identical shape, bonded together with a diagonal stagger, so that a projecting overlap zone exists along the sides. This overlap zone is also coated with adhesive, which remains permanently active. More specifically, a melting adhesive, for example thermoplastics rubber contg. a resin and filler is used. With this arrangement, when the tiles or slabs are laid, their overlapping joints bond together; this prevents subsequent displacement during the rough treatment of laying the underfloor heating pipes. Furthermore, the sealing effect through this layer of panels to prevent penetration of the floor rendering or finish through to the structural slab, is improved.

It has a plumbline detector, whose output signal is fed to a unit controlling the sieve opening width. This can be arranged to increase the latter when travelling uphill and to decrease on downhill. The detector and the control unit can be hydraulic. As a further alternative the detector can be an oil-damped pendulum on a fixed part of the combine harvester.

Title: DC load supply using AC power - has auxiliary thyristors, commutator chokes and capacitor reducing total number of main thyristors required (SE 5.7.82)
Inventor: LIENAU WOLFGANG DIPL ING DR
IPC: H02M5/45
Filed: 1980-12-06
Abstract: A supply circuit for a d.c. load supplied from a single or multiple phase a.c. source via a mains transformer contains a two stage two quadrant controller. The main thyristors carry only load current during their conducting phase. A central discharge device and simple drive are used. Main thyristors are connected between the diode bridge connections on the d.c. side. A commutator choke and decoupling diode are connected in each conductor between the d.c. connections of the diode bridges and the common point of all parallel bridges. A series circuit contg. an auxiliary thyristor, a commutator choke and a common commutation capacitor is connected to each connecting conductor after the first commutating choke. The arrangement requires fewer main thyristors than usual without increasing the feedback to the mains or degrading the smoothing characteristic.

Patent DE-3134540-A1 (DE)
Inventor: YASMASHIRO OSAMU
IPC: H02M3/07
Filed: 1981-09-01
Abstract: According to the present invention, the voltage of a battery is supplied to an electronic circuit such as a watch circuit through a step down circuit which is constructed of capacitors and switching MIDFETs. The step down circuit performs a current converting operation as well as a voltage converting operation. The operating current of the electronic circuit is reduced by the reduction in the operating voltage of the same. As a result that the operating current level of the electronic circuit is dropped and that the current conversion is performed by the step down circuit, the battery current is relatively largely dropped. The construction thus far described elongates the lifetime of the battery. According to the present invention, therefore, there is provided a circuit which is proper for driving the step down circuit.

Patent DE-3219562-A1 (DE)
Inventor: CHITIL MANFRED DR ING
IPC: C10J3/08
Filed: 1982-05-25
Abstract: A coal gas supply method converts a carbon carrier in a reactor into a coal gas by the addition of oxygen and feeds the coal gas to fuel consumers. To ensure a continuous fuel supply to the fuel consumers during the coal gasification process, a branch current of the coal gas produced is liquefied and stored. At the same time the oxygen stored in liquid form is drawn from a tank, evaporated and used in the reactor. If there is a breakdown in the coal gasification process, the stored quantity of coal gas is evaporated gradually and fed to the consumers. At the same time, oxygen drawn from an oxygen inlet pipe is liquefied and stored. Instead of coal gas, another fuel gas such as natural gas can also be used.
