Title: Ultrasonic material fault detector using sector-shaped scanning beam - which is provided by phased array and measuring characteristic of max. echo amplitude curve
Inventor: GEBHARDT WOLFGANG DR
IPC: G01S7/52
Filed: 1979-01-18
Abstract: The fault detector uses ultrasonic waves provided by a phase-controlled array, with differing radiation angles relative to the tested material. The combined radiated beam covers an angular secotr of 90 deg., with the returned echo signals synchronously displayed on a viewing screen. This provides a spread out sector image, with the periodic position variation of the defect echo used to obtain the fault parameters. Pref. the max. signal amplitude (Ux) is determined for different points (x) along the scanned sector, with the highest point of the curve displaying the max. signal amplitude occuring directly above the fault, where the length of the wave propagation path is least. The sharpness of the curve gradient either side of the highest point is measured to obtain the angle at which the flow lies relative to the material surface etc.

Title: Outboard motor reverse thrust booster - has slide valve with sector keyed to propeller shaft to respond to change in direction
Inventor: FINZE FRITZ-JOHANN
IPC: B63H1/28
Filed: 1979-03-26
Abstract: The valve consists of the sector and disc with drivers. The disc is either integrated with the plate or itself forms the thrust plate. The plate forms a stepped design to allow the disc to rotate between end and main plate area. The sector is keyed to the plate. The valve unit can be positioned either end of the propeller boss in which case plate is used as mounting. The propeller uses blades for propulsion and the shaft channel continues the exhaust channel and terminates in the boss. The booster is for outboard motors in pleasurecraft. The valve shows an improvement in back thrust from 45 to 80 Kp coupled with rising speed characteristic. The propeller movement is automatic between forward and reverse positions with the valve responding to the change in propeller direction accordingly to divert the exhaust and thus keep it clear of the propeller intake area.

Abstract: Data describing unsuccessful calls is stored in a memory for calling up when the wanted extension becomes free. The connection circuitry engaged by the unsuccessful calling subscriber is connected to a special call-back memory when the called extension is either engaged or not answering - provided the calling subscriber has persisted for a given min. time. A message memory is associated with the call-back memory and allows the unsuccessful caller to leave his telephone number so that the called subscriber can call back later. The unsuccessful caller speaks his number into the message memory. The call-back memory is connected to the called extension to transfer the data describing the unsuccessful caller to the called extension when the latter wishes to call back. The extensions are alloted authorisation codes defining regions within which they may make call-back calls.
Patent DE-3015879-A1 (DE)
Title: Electronic release safety ski binding - has circuit to adjust release force statistically according to assessed skiers weight
Inventor: KNABEL WALTER DR
IPC: A63C9/08
Filed: 1980-04-24
Abstract: A safety ski binding with electronic or microprocessor based circuitry to assess the vertical and rotary forces on the foot at the ball and heel so that the ski binding can be released if they become dangerous. The circuitry does not require prior adjustment to set a value for release forces according to the weight of the skier. The circuitry independently determines its own quasi-statistical criteria for release by responding to the weight of the skier when the skis are being fitted. Allowance is made for skiing on one or both feet and release force limits are set accordingly. The front and rear weight measurements made are summed and entered into the processor or circuit programme to adjust the release point. The circuitry interprets the forces and time periods of duration according to its programme and the release points determined and accordingly commands the binding release. Interpretation of the rate of increase of the forces is also used for release control.

Title: Porous sintered metal prods. for filters etc. - made using both coarse and fine metal powders, and two sintering operations
Inventor: VITIJAZ PETR A
IPC: B01D39/20
Filed: 1980-05-14
Abstract: A coarse metal powder (I) is moulded or pressed and sintered to obtain a porous blank. The pores in the blank are then filled with a fine powder (II), followed by heating to the sintering temp. of powder (II). During the filling of the pores in the blank with powder (II), the latter is pref. fluidised by vibration, or is subjected to ultrasonic vibration. Conventional methods of mfg. porous sintered prods. normally result in permeability values which are too low. The invention avoids this problem. Used in mfr. of filters for cleaning gases or liq.; wicks for heat exchanger tubes; or porous cooling elements. The prods. have adequate mechanical strength, plus a uniform permeability which is higher than when only one powder is used.
Patent DE-3026622-A1 (DE)
Inventor: LANZ OTTO
IPC: H04J3/04
Filed: 1980-07-14
Abstract: By staggered time delays ( DELTA t2 ...  DELTA tn) within an input multiplex channel (E) of a TDM circuit with correspondingly staggered periodic scanning and intermediate storage (AT) and analog-digital conversion (W), in spite of the scanning delay and the corresponding shifted timing of the scanning times, a corresponding assignment of the scanned values by time is achieved. The staggered time delay is given especially simply and thus advantageously by corresponding measurement of the upper limiting frequency in the filters assigned to individual input channels. <IMAGE>

Title: Anti-theft detent for door stops
Inventor: DELECKER WILLY-MAX EDUARD
IPC: E05C19/16
Filed: 1981-02-26
Abstract: The main application P 2952615.6 describes, inter alia, a door stop which consists of a door-stop housing holding core screwed to the floor and of a door-stop housing which can be slipped over this door-stop housing holding core. The present additional application discloses an anti-theft detent for this device. The anti-theft detent consists of a catch-receiving groove in the fixed door-stop housing holding core and of the catch strip in the door-stop housing, which, when the device is in the position of use, is located opposite the catch-receiving groove in the door-stop housing holding core. Pushed into the catch-receiving groove is a catch spring which possesses catch noses on one side and catch-spring noses on the other side. The catch-spring noses are formed obliquely on the catch-spring body in such a way that the entirety can easily be pushed into the catch-receiving groove, but thereafter the door-stop housing can no longer be pulled off from the door-stop housing holding core screwed to the floor, because the catches on the catch spring are pointed in the opposite direction to the pulling-off device and therefore block the pulling off of the door-stop housing. The drawing, sheet 1, together with Figure 1a, clearly illustrates, in section, the device of the door stop, with the accompanying cutout of the door, and the magnetic clamping plate located on it as well as the anti-theft detent device.
