Patent DE-2924373-A1 (DE)
Title: Suppression of pulse type noise signals from disc recording - using detector for abrupt reduction of amplifier gain for duration of disturbance
Inventor: SCHROEDER ERNST DIPL ING
IPC: H03G3/34
Filed: 1979-06-16
Abstract: The suppression circuit is principally for disturbing signals emanating from disc recordings, partic. pulse type. When operating at low signal levels, with dynamic expansion circuits active, a pulse distortion is also amplified, and the decay time to reach the original signal level can be relatively long. To overcome this undesirable feature a pulse distortion detector is used. This acts on rate of change and relative amplitude of the signal coming from the disc. When such a signal is detected the expander amplifier gain is instantaneously reduced to a low value, and held low until the disturbance is over. The effect of the disturbance is thereby practically unnoticeable in the resulting output. The circuit can operate by solid state switching of a different amplifier reference voltage for the duration of the disturbance.

Title: Solar water heating system - uses several stages incorporating dark absorber tubes and plastic lenses in adjustable units
IPC: F24S23/30
Filed: 1979-08-29
Abstract: The system uses solar energy to heat washing water either directly or via a frost-proof liquid flowing in a closed cycle. Heating is in several stages, the heated water being collected in separate insulated vessels after each, the vessels being connected by pipes and circulation controlled by valves actuated by temperature detectors. In the first stage uninsulated hoses or pipes absorb the heat from short-term and otherwise unutilised sources, while the second one uses solar heat direct, with hoses or pipes having external transparent walls and internal dark-coloured tubes through which water or fluid is pumped, and held centrally by distance pieces. The third stage comprises plastic transparent lenses with dark absorber tubes (10) on the focal lines, the tubes having metallic absorber surfaces. Each fixed or pivoting multiple-lens unit is a fully-closed body with insulating side faces (5) mounted on a semicircular bracket (7) adjustable to suit the season and ray direction. The first and last ones struck by the sunrays turn on the bracket. The degree of heating is adjusted by the flow rate of the water or fluid.

Title: Special unit control in computer controlled exchange - is effected without group controller by pairing it with regular unit
Inventor: LAAS KURT
IPC: H04Q3/54
Filed: 1979-09-04
Abstract: In a computer controlled telephone exchange, access to the switching system is by means of various types of peripheral unit (GS), permanently wired in. The units are controlled, via group controllers, by the central controller (ZST), which addresses them and stores their addresses for the duration of a connection. Special units, e.g. for feeding in 50Hz pay pulses, are required for a small percentage of connections, but it is not economic to provide them with a group controller. The control input of a special unit is connected, via the main distribution frame, to the control circuit of one of the regular 'going-set' units, which then becomes its 'partner'. The central controller can then address the special unit via the partner and its group controller. This does not affect the functioning of the partner, which may be simultaneously engaged in some other unrelated connection.

Title: IGFET with controllable gate and floating storage gate - has window, or gap, over storage gate on protrusions on either side of optically quenched P-channel
Inventor: ROESSLER BERNWARD DIPL ING
IPC: H01L29/788
Filed: 1979-09-24
Abstract: The field-effect transistor is of a stacked-gate avalanche metal oxide silicon, or floating-gate avalanche metal oxide silicon type (SAMOS or FAMOS FET). Its floating gate is completely surrounded by an insulator and serves for storage purposes. Due to the avalanche effect this gate is charged in correspondence to the minority charge carrier of the drain. The transistor is particularly intended as an optically quenchable p-channel SAMOS-PROM of a TV transmission system. The control gate (G2) above the storage gate (G1) and/or the upper projection, distant from the substrate, of two such projections provided on the storage and control gates, laterally of the channel, has at least one window, or a gap (BF, Bf) on the mutually overlapping projection parts. The storage gate is discharged by short-wave electromagnetic radiation. A normal substrate (Su), or the source (S) potential is applied to the control gate, to which the radiation (UV) is applied, as well as possibly to the storage gate via the window.
Patent DE-2947721-A1 (DE)
Title: Piezoelectric tuning fork resonator - combines low current consumption with HF stability by using exciting electrodes on fork arms producing both torsion and bending
Inventor: MOMOSAKI EISHI
IPC: H03H9/215
Filed: 1979-11-27
Abstract: The crystal disc is cut so that its plane is inclined against the optical axis Z by a specified angle, and the tuning fork cut from the disc forms an angle of about 20 deg. to the electrical axis X. Furthermore the exciting electrodes deposited on the tuning fork arms are arranged to produce both torsional and bending forces so that, oscillations occur partly in the bending and partly in the torsional modes, dependent on disc thickness. At a certain disc thickness optimum coupling between the two modes occurs and the two frequencies merge into one. Optimal independence from temperature effects, however, exists where the two modes differ w.r.t. their oscillator resistances by a factor of ten. These partly contradicting requirements can be reconciled by careful dimensioning of the tuning fork, and by choice of the crystal axis deviations. The result is a resonator having about 70 times better stability between 0 deg.C and 40 deg.C than a conventional tuning fork resonator.

Title: Tyre cast in mould with inflatable diaphragm - using mould for carcass then substitute shell in tread zone for second elastomer filling
Inventor: KEMPTER MICHAEL
IPC: B29D30/06
Filed: 1980-07-10
Abstract: Method of casting a tyre of castable elastomer in a mould uses an inflatable diaphragm, which is initially expanded to fit into the mould, and then deflated or contacted progressively as the elastomer is introduced. The elastomer for the tyre carcass is first introduced through a first duct (24) into the mould, then the tread zone mould part (20) is replaced by one of a different form (28) containing the tread shape, and then further elastomer for the tread zone is introduced through a second duct. The separating diaphragm (4) is thus pref. stretched across the surface of the main diaphragm in the tread zone. The arrangement enables two different materials to be used for the carcass and the tread region.
