Patent DE-2934449-A1 (DE)
Title: Protective devices in communication equipment to ensure security - have code recognition register control over transmitting mains switch
Inventor: WIECHMANN MANFRED DIPL ING
IPC: H04L9/00
Filed: 1979-08-25
Abstract: In a communication receiver (1) intended for printout (12) of received messages a protective hood (13) is provided which when closed is latched and cannot be opened except by a special key. The closed position is sensed by a contactor (41) which enables a code generator (23); the same is triggered by a check word decoder (18) which receives a check word from a transmitting unit (2) via a communication line (3) where it is produced in a check word generator (14) upon depression of a push-button (48). The recognition output (19) is applied to an AND circuit which also receives the recognition code (24). The same is applied to an AND gate (46) via a code acceptance transmitter (27) and a line (28) to the transmitting unit (2). Here it is applied to an acceptance signal receiver (29) and associated decoder circuit (30) which, if the code was correct, closes the message main transmitter switch (7) and lights a lamp (32) to indicate readiness to transmit. If the hood had been left open, this procedure would be impeded.

Abstract: The alloying rods can possess any desired dia. within a limited range without requiring any major adjustment of the machine. The machine drives the rod towards the melt via driving rolls and guide rolls, which are easily replaced to suit rods with a polygonal cross-section. The speed of the motor driving rolls can pref. be altered continuously to vary the delivery speed of the rod from zero to max. The machine pref. includes a transducer measuring the length of rod delivered to within e.g. 0.2m and displaying the length on an illuminated meter. An electronic pulse counter is pref. used to switch off the motor when a prescribed length of rod has been fed into a melt. Automatic feeding of a desired wt. of alloying rod into a melt.

IPC: F04D7/04
Filed: 1980-08-07
Abstract: The centrifugal pump is designed as a helical-blade pump having at least one single-suction impeller (3) with a delivery duct whose course is helical. Preferably, the impeller (3) in the intake section (8) - starting with a tip (4) situated on the outside - has an inner edge (5) which rearwards continuously slopes downwards towards the centre in the direction of rotation. The external shape of the impeller (3) may be cylindrical or conical in the intake section (8), the impeller blade (6a) ending, in the outlet-side casing section, in a cylindrical impeller hub (9). It is possible to deliver highly viscous liquids, sludges and the like with a solids content of 70%, large deflection radii ensuring a gentle delivery which is important for economically useful objects in liquids. A high hydraulic efficiency of up to 85% is achieved. Braiding in liquids laden with materials consisting of long fibres is virtually precluded. <IMAGE>

Title: Reciprocating IC engine with slide control - has pistons pivoted on inclined disc to convert reciprocation into rotary output motion
Inventor: METZ HORST
IPC: F02B75/02

Title: Steering column light switch mechanism - has three-position switch with dipped rest flash central and head upper position moving double sprung main leaf spring
Inventor: ERDELITSCH HERBERT
IPC: B60Q1/14
Filed: 1980-08-30
Abstract: The three position switch is at rest in the dipped beam position and is moved through the flash position to the high beam. The lighting main switch may also be on the stalk. The object is to avoid direct switch-on to the high beam position and to have flash in one direction from rest and high in the other direction, e.g. rest centre with one up and one down. The three positions (I,II,III) leave the main leaf spring contact units (16) at rest, then pivot it (16) down against the first contact (33) but leaving it in contact with one side (18,30) because the pressure is insufficient to overcome the central spring (39), and finally the pressure overcomes the spring (39) in position (III). In this third position (III) the central leaf spring (16) remains in contact with the first contact (22,33) and leaves the second side contact (18 from 30). The spring (39) is compressed and the first contact (33) leaf spring (35) is pressed down against an end stop (38) with the central leaf spring (16) also hitting and end stop (36).

Title: Mfg. acicular goethite of small particle size - by adding zinc salt and alkali to ferrous soln., precipitating ferrous hydroxide, adding chlorate and oxidising
Inventor: HAMABATA TOSHIHIRO
IPC: C01G49/06
Filed: 1980-11-14
Abstract: Mfr. of acicular goethite, comprises adding zinc salt and alkali to aq. ferrous salt soln. to adjust the soln. to above pH 11, pptn. of ferrous hydroxide, adjusting proportion of anion to ferrous ion to below 1, adding sodium chlorate or potassium chlorate, and carrying out oxidn. reaction at below 80 deg.C. The process reduces reaction time and gives acicular goethite having small particle size. In an example, to 1.0L of water there were dissolved 167 g of FeSO4.7H2O and 0.86g of ZnSO4.7H2O, and 168g. of NaOH and water added such that total volume becomes 1.5L. The soln. was allowed to stand for 6h. to form ppte. of ferrous hydroxide. 750mL of supernatant liquid was removed, by which proportion of anion to ferrous ion was adjusted to below 1. Next, to this, there were added 12.3 g of potassium chlorate and 0.37g of sodium silicate soln. and added water such that total vol. becomes 1.5L. The soln. was allowed to react at 50 deg. C for 8 h. The ppte. so produced had the structure of acicular goethite. The magnetic properties of the alloy obtd. by reduction of the acicular goethite (alpha-Fe(O)OH) at 400 deg.C were as follows: Hc:1450 Oe; sigma s:130 emu/g; sigma r/sigma s:0.56. (4oo).

IPC: B65H54/54
Filed: 1980-12-03
Abstract: The spool mandrel with horizontal axis comprises a driven rotary spool spindle, a stationary housing, and a spool sleeve rotating with the spindle. At both ends of the spindle (1) between it and the housing (2) are bearings (1') while there is a further bearing (4) between the sleeve (3) and the housing at the housing end of the former. This bearing (4) is a clearance fit in the radial direction in the sleeve or on the housing, so as to form a gap between them, filled with incompressible material which can flow, such as oil or grease. Seals such as O-rings in the gap prevent this escaping.

Title: Method of controlling the drill rod in the vertical plane and apparatus for carrying out the method
Inventor: FUCHS HEINZ
IPC: E21B7/08
Filed: 1981-01-15
Abstract: Horizontal bores are controlled by means of stabilising devices surrounding the drill rod at a distance. In the case of larger annular spaces between drill rod and borehole wall, a so-called centrifugal effect of the drill rod interferes with this type of control. To avoid this disadvantage and to guarantee the control of the horizontal boring in the vertical plane, the control operation in bores with larger annular spaces is regulated via an additional auxiliary stabilising device, which is arranged on the drill rod between the first two stabilising devices downstream of the drill bit and is smaller but adjustable in diameter, as well as via the adjustability of the first stabilising device downstream of the drill bit. <IMAGE>

Title: Circulation breathing apparatus
Inventor: LEHMANN KLAUS
IPC: A62B7/10
Filed: 1981-02-17
Abstract: The invention relates to a circulation breathing apparatus whose breathing-out line is connected to the breathing-in line via a CO2 absorber and a compensating container. In order to make such an appliance usable also for so-called superatmospheric pressure operation, the compensating container is loaded by an external force which maintains a pressure increase in it sufficient for superatmospheric pressure operation. In this case, it is particularly favourable to conduct the force acting on the compensating container away from the mean pressure of the system so that, regardless of the amplitude of the compensating container, the force acting on it remains the same.
