Title: X=ray generator system for tomography appts. - has radiation detector delivering signal setting tube control elements to regulate X=ray intensity
Inventor: MESTER HEINZ
IPC: H05G1/60
Filed: 1976-11-06
Abstract: The generator has a radiation detector (6) which delivers a signal depending on the dose of energy or on the dose behind the object (5). This signal is used for control of the X-ray tube (1). Means are provided for automatic connection of the tube initial current and/or voltage for exposures of a series following the first exposure. The generator has means (12, 13) for storage of the tube current or voltage values produced by the control process. They are used for setting control elements (3, 11).

Title: Telephone exchange fault tester - applies clean-up pulse to faulty contacts and disconnects corresponding path if fault persists
Inventor: ZWACK EDUARD ING GRAD
IPC: H04Q1/24
Filed: 1976-11-16
Abstract: A telephone exchange with a relay-operated switching matrix (KF) has a built-in facility for testing subscriber connections. Following disconnection of a subscriber (TLn), a voltage tester (X-I, X-II, S-I, S-II) is connected to the lines (a, b) by way of the contacts (p1, p2) of a test relay. If a faulty connection is indicated by a voltage on the voltage tester of a central control unit is obtained, a "clean-up" pulse is applied to the contacts. If the fault indication then persists, the information is stored in the central device and the corresponding path is not reactivated until repair has taken place.

Title: Synchronised sequential operation of traffic lights - is modified automatically by counting vehicles leaving controlled section
Inventor: STEIN HERMANN
IPC: G08G1/07
Filed: 1976-12-23
Abstract: Traffic lights are used to control traffic at roadworks where a single track exists. The lights are synchronised to provide sequential operation which can be modified by counting vehicles leaving the controlled section. Traffic lights which are spaced apart to control traffic at roadworks are operated sequentially by a control unit. A synchroniser generates periodic sync. signals with a duration corresponding to the sequence period. Facilities are provided for automatic or manual operation of the phases which can also be controlled by counting the vehicles leaving the section of road. The count is compared with a predetermined number to readjust the sequence timing.

Title: Heat exchanger element - with tubes in even rows offset against odd rows and ribs of alternating width leaving air access channels
Inventor: HEEREN HERMANN
IPC: F28B1/06
Filed: 1976-12-24
Abstract: A heat exchanger element with consecutive rows of ribbed tubes has the tubes of the odd rows off-set relative to those of the even rows. The ribs of the odd rows are equally spaced but wide square ribs alternate with small square ribs. This creates air access channels to the equal-width ribs of the even rows which have double the spacing. Arrangement results in a much smaller transverse pressure loss for the same amt. of heat dissipated per incident flow area.

Title: Feeding radioactive waste container into hot cell - through shielding hatch by handling container transferring it from wagon
Inventor: NOLTE KARL-HEINZ
IPC: B65G63/04
Filed: 1977-01-27
Abstract: A device for feeding individual radioactive containers winto a hot cell comprises a transporting wagon or truck, on which a shielded container designed to hold many individual containers is mounted, and also a handling crane in the associated shaft hall. The inlet to the hot cell from thet shaft hall is normally closed by a sliding, shielding hatch; a handling container, in which one individual container is housed is deposited on this hatch by the crane. Pref. the handling container has a sliding hatch in its base, which enables it to be coupled to the shielded container on the wagon and also to the sliding hatch, thus enabling the individual container to be transported from the multiple container into the handling container and again from the latter through the hatch and into the cell. Used in particular for handling containers in which medium-activity radioactive waste is contained. The appts. is simple and robust in its construction, reliable in operation and will enable increasingly large quantities of radioactive waste to be reliably handled without risk to operating personnel.

Title: Two=part housing for liq. flowmeter - has internal enamel coating to inhibit corrosion and has sealing rings which are in contact with enamel layer (NL 12.12.78)
Inventor: MAEDLER ARMIN ING GRAD
IPC: G01F15/14
Filed: 1977-06-10
Abstract: The liquid flow meter (1) has an upper housing component (2) and a lower housing component (3) both of which have an enamel anticorrosion coating (4) on their inner surface. In the region of the abutting surfaces (5, 6) of the two components, the enamel layer extends towards the exterior; a further extension (7, 8) is not covered by the enamel. This extension has precise dimensions which correspond with the dimensions of a mounting extension (13) on the frame of the liquid flow measuring appts. (14) and serves for its precise location. The absence of the enamel layer permits alignment of the axes of the appts. and the housing. The two housing components are clamped together and sealing rings (15, 16) are held against the enamel layer to prevent egress of the corrosive liquids.

Title: Electrical discharge machining of cylindrical surface - by varying working current at cylinder ends to uniformly satinise latter(s)
Inventor: SATO KUNIHIKO
IPC: B23H1/02
Filed: 1978-07-13
Abstract: Outer surface of cylinder is satinised using electrical discharge machining by rotating the cylinder and moving at least one electrode in a direction parallel to the axis of rotation of the cylinder. A pulse voltage is applied across the electrode. When each end of the cylinder is being worked the working current per unit working area of the cylinder is maintained constant by decreasing the working current as the working area decreases so that the outer surface at each end of the cylinder is uniformly satinised. The current may be varied by varying the off time of the pulses.

Patent DE-2833427-A1 (DE)
Inventor: STOEHR RUEDIGER DIPL ING DR
IPC: B28B7/00
Filed: 1978-07-29
Abstract: In the case of the wall panel (22) consisting of aerated gypsum, at least part of its border region, close to the surface, has a higher density than its central region. The process for producing the wall panel provides that at least part of the border region, close to the surface, of the structural part is compacted, in doing so reducing the pore volume with respect to the central region. In the case of the apparatus for carrying out the process, it is provided that at least one shaped part (18, 20) is designed such that it can move, and, towards the end of the casting period, a drive device (24, 26) can apply pressure to it in the direction of the central region of the setting structural part. <IMAGE>

Title: Video signal transmission over narrow band channel - using transformation code and displaying picture continuously during reconstruction
Inventor: MANGOLD HELMUT DIPL ING
IPC: H04N19/60
Filed: 1978-08-12
Abstract: The transmission systems uses transformation coding to convert samples of the picture signal into spectral coefficients which are then sent consecutively to a receiver. At the receiver the spectral coefficients are stored and continuously subjected to re-transformation. The reconstructed picture is displayed continuously during its reconstruction phase. Spectral coefficients of the lowest order are transmitted first and then those of the next highest order, and so on. The advantage lies in the picture's being displayed as soon as possible at the receiver.
