Patent DE-2415366-A1 (DE)
Inventor: MEYER FRANZ JOSEF
IPC: G11B20/12
Filed: 1974-03-29
Abstract: 1495459 Automatic control SIEMENS AG 12 March 1975 [29 March 1974] 10205/75 Heading G3N The speed of a magnetic tape is controlled by a time varying reference having a portion that is triggered by a tape start signal rizes linearly to a nominal tape speed, and a part that is triggered by a tape stop signal and falls at a greater rate. In the embodiment, tape drive motor MO is controlled according to the difference between an actual motor signal # from tachometer TA and the speed reference from device ST via potentiometer p which sets the nominal tape speed. The device ST, described with reference to Fig. 4 (not shown), is triggered by a binary start/stop signal S, to charge a capacitor at a given rate e.g. corresponding to the maximum permissible tape acceleration to give the rising speed reference, the capacitor being discharged at a faster rate by a switching transistor to provide the falling characteristic. The motor MO, and thus the tape, may be reversible. The above system minimises gaps between adjacent blocks of stored data on the tape.

Title: Elastic mounting of bumper bar - has tensioned, cylindrical pads and non-extending tensioning shaft
Inventor: HAEBERLE FRITZ
IPC: B60R19/30
Filed: 1975-03-13
Abstract: The bumper bar (7) is joined to the chassis support (3) by hollow cylindrical, rubber, damping members (4). A mounting shaft (6) is rigidly attached to the rear of the bumper bar at every damper position, and is taken through the damper and through a hole in the chassis support. The end of the shaft is fitted with a removable tommy bar (12) so that the shaft can be secured over the end of a fitting sleeve (9) which is positioned between the rear of the chassis support and the bar. This tensions the damper pad and prevents the bumper bar from rattling. The sleeve and tommy bar also reinforce the bumper mounting so that the vehicle can be towed using the bumper without the danger of shearing the dampers.

It starts the pulse counters. The second sensor delivers a signal when the workpiece rear edge passes it. It stops the counter. The third sensor stops the counter when the front edge of the workpiece passes it. The distance between two sensors is adjusted to the length of workpiece to be measured, pref. to the nominal length plus maximum upper tolerance.
Patent DE-2517128-A1 (DE)
Title: Plasma welding pistol with water cooling circuit - where electricity flows only while water travels through drain from pistol
Inventor: MATTHESS RUDOLF
IPC: H05H1/28
Filed: 1975-04-18
Abstract: Plasma welding appts. with a coolant circuit contg. a pressure switch between the coolant supply and the welding pistol, so that electric current only flows to the pistol when the pressure of the coolant actuates the switch. The novelty is that monitoring devices are provided in the coolant circuit downstream of the pistol to cut off the electricity if the outlet flow of the coolant stops or drops to a small amt. The monitoring element pref. consists of a switch located in the drain from the pistol and which cuts off the electricity when the coolant flow through the drain drops below a min. amt., esp. using a switch operated by capacitance and steering a relay. Although the pressure switch prevents the supply of electricity when coolant pressure is absent, it does not cut off the supply if a blockage occurs and no coolant leaves the pistol, i.e. producing damage. The invention ensures that electricity is only supplied while coolant is flowing out of the pistol.
Patent DE-2517946-A1 (DE)
Title: Welding tubes in plates for heat exchanger mfr. - where rings of filler wire are put counterbored holes in plate
Inventor: AMBS FRITZ
IPC: B23K9/028
Filed: 1975-04-23
Abstract: Welded joint between tubes and the plate or plates in a heat exchanger, where the tubes are inserted in holes in a plate and welded from the inside. Rings made of weld filler material are placed in the joints and form part of the weld. The ring pref. consists of wire, cut to length and bent to form a ring slightly larger in dia. than a counterbored hole in the plate, so the ring is held in the counterbore by elastic deformation, i.e. by the spring in the split ring. The wire used to make the ring pref. has a dia. corresp. with the wall thickness of the tube. Used in mfg. heat exchangers for chemical plant using tubes with max. dia. 20mm. so it is not possible to use a filler rod. Due to the absence of the filler rod, structural transformations can occur, esp. the formation of ferrite in an austenitic stainless steel, thus impairing corrosion resistance. The invention overcomes this problem.

Title: Continuous mixer for preparing cement slurry for use in wells - in which cement is entrained in angularly adjustable flat jet of carrier liq.
Inventor: MAMVRIJSKIJ ALEKSANDR S
IPC: E21B33/14
Filed: 1975-07-31
Abstract: A mixer for preparing a controlled density cement slurry for use in e.g. oil and gas wells is claimed. Dry cement is supplied in a first direction to a mixing chamber while a flat jet of carrier liq. is directed through the chamber in a direction normal to the first direction from a nozzle to an aligned outlet part of the chamber, the jet intersecting the incoming stream of cement. The nozzle is rotatable about its axis to adjust the orientation of the jet about its longitudinal axis and thereby control the amount of cement which becomes entrained in the jet. Density variations can be effected rapidly and without requiring variation in the rate of flow of the carrier liquid.
