Title: TV camera or picture tube - with unequal sided groove and tongue joint between front and cone glass part
Inventor: BOEKE KLAUS DR RER NAT
IPC: H01J29/86
Filed: 1978-12-08
Abstract: A camera or picture tube for black/white or colour TV consists of a front glass part and a cone part which are joined by glass frit bonding a groove in the cone rim to a tongue on the front rim. The groove has convex sides of unequal length (the longer inside) and the tongue has corresponding concave sides. Three raised parts at the groove bottom and on the tongue top are in contact with each other. This reduces the grinding costs for the shorter contact areas. The escape of any glass solder inside the tube during assembly is eliminated.

Title: Moving coil loudspeaker with feedback arrangement - has parabolic reflector with optical sensor in circuit with output amplifier
Inventor: THIELE KARL-HEINZ DIPL PHYS
IPC: H04R3/00
Filed: 1978-12-13
Abstract: The membrane (17) of a moving coil loudspeaker has a mirror-like surface (18) on its concave surface which acts as parabolic reflector. A source of light (21) mounted in a cylindrical opening of the axial core of the loudspeaker magnet system (12, 13, 14) casts a beam of light onto the mirrored face of the membrane in such a manner that the reflected light converges on a light sensitive cell (20) positioned close to the focal point of said mirror. Axial movements of the membrane would be accompanied by a shift in the focal point and therefore by corresp. increases and decreases of the light density received by the photocell (20). From this, derive signals that may be fed back to the input of the output amplifier. The concept can be realised also in modified forms. Common to the different versions is the fact that the membrane of the moving coil and its excursions from a quiescent condition determine the amount and phase of the negative feedback.

IPC: G06K19/00
Filed: 1979-04-06
Abstract: A system for recording data is disclosed, which relate to lots to be collected, particularly to milk lots to be delivered to a central collecting station. A recorder installed on the collecting vehicle comprises the normally existing data memory and closely adjacent thereto a second memory, which has preferably the same structure and serves to store those data which are required in an analytical laboratory for an analysis of samples taken from the lots as they were collected. These data are recorded in the second memory under the control of a selector. By means of the second memory, a separate data carrier is provided, which is delivered to the analytical laboratory, in which data representing the result of the various analyses are recorded on said data carrier so as to supplement the data originally recorded thereon. In this way the data can be fully automatically collected and processed, uniform technology can be used in the system required for this purpose and, as a result, the equipment used on the collecting vehicle and in the analytical laboratory can be simplified and the overall functional reliability can be improved.

Title: Hot water supply system for underfloor heating - uses correction system in circuit with external and hot water temp. sensors
Inventor: FRENDLIEB HELMUT
IPC: F24D19/10
Filed: 1979-09-29
Abstract: The hot waterupply system for the heaters for an underfloor heating installation has a clock for operating at different levels for day and night, and uses an external temperature sensor. The actual value of the hot water supply is continuously monitored and the heating reduced when a maximum value is reached. The input to at least one heater is measured and compared with a nominal value to control the temperature. When the clock operates a switch to increase the temperature from the level for night time, a signal is passed to a flip-flop to operate a multi-way valve, connecting it with a temperature sensor in the return flow path and the external temperature sensor and a limiting value controller. These values are equalised with a predetermined reference value and a return setting operation is carried out to correct the heat requirement.

Title: Measuring building material and land deformation characteristics - uses steady force applied to punch and measuring penetration
Inventor: MOROSOV VIKTOR N
IPC: G01N33/24
Filed: 1980-02-15
Abstract: The deformation characteristics of building materials and building land consists of applying a force to a punch resting on the tested object and measuring the resulting displacement of the punch. It is an efficient method giving load-independent results which are accurate over a wide range. The punch has a defined dia. and is subjected to an increasing force until it has moved a distance equivalent to between 0.03 and 10 dia. The applied loading is then gradually reduced and the elastic movement of the punch is measured. For building materials the penetration range of the punch is between 0.03 and 0.3 of the punch dia. For homogenous earth layers the penetration range is from 0.05 to 1.0 times the punch dia.
