Title: Covering rotary furnaces with refractory material - bonded by fast cured thermosetting resin adhesive
Inventor: ZACHWY OTTO DIPL ING
IPC: B29C65/48
Filed: 1972-06-22
Abstract: Heat curing of the adhesive bond of a synthetic resin adhesive in a lying cylinder is effected, esp. in a rotary furnace, in order to rapidly and securely bond refractory material to the outside of the furnace cover, by rapidly heating the thermosetting resin adhesive on the outside of the furnace cover to a temp. which does not harm the strength of the adhesive bond, and maintaining this temp. for a definite curing time which is sufficient to reach the final strength of the adhesive bond in the shortest possible time, this time being determined experimentally previously for each special type of resin.

Patent DE-2325599-A1 (DE)
Title: Flash welding slide reversal control - by relays responding to harmonic waves and voltage collapse
Inventor: PASTORS PETER
IPC: B23K11/24
Filed: 1973-05-19
Abstract: The reversal control for the slide of a flash welding machine is effected by a first relay which responds to the welding voltage, a second relay which responds to its harmonics, and a third relay which responds when the electrode voltage collapses, in conjunction with a store for the sinusoidal peak electrode voltage. The reversal is controlled by the frequency differential between the fundamental wave and the superimposed harmonic waves which characterise the flash welding operation, combined with the difference between current and peak electrode voltage. This system saves the repeated readjustment of transformer tappings. It does not depend on the variable (with varying electrode voltage) response and drop-out times of the relays and is suitable for any welding program.

Title: Front mounted implement coupling system - tractor has hydraulic height adjustable draw bar with indicator scale
IPC: B60D1/46
Filed: 1973-06-29
Abstract: To facilitate front trailer coupling to a tractor, a cone shaped coupling cover adjustable for height from the driver's seat is provided with a scale whose indicator is connected by a pull wire in an outer sleeve to the hydraulic coupling adjuster piston. Since the coupling parts are not visible to the driver, a sighting marker is fitted to the front edge of the tractor engine cover, from which the driver takes a bearing to a similar marker fitted to the trailer. The tractor coupling cone is carried on parallelogram arms raised or lowered by a hydraulic piston and cylinder.
Patent DE-2344964-A1 (DE)
Title: A.C. operated D.C. motor speed control - has variable D.C. voltage feed and signal cct. generating current proportional signals
Inventor: BELMUTH NEAL W
IPC: H02P7/293
Filed: 1973-09-06
Abstract: The d.c. motor is operated by a.c. from a source connected to a supply circuit which feeds to the d.c. motor a variable, rectified voltage. The speed control uses a signal circuit generating signals proportional to the current supplied by the a.c. source. According to the signal magnitude the rectified voltage, feeding the d.c. motor is changed for regulating the motor speed. This is carried out by a pulse generator parallel to the supply circuit, provided with the output signal time control with respect to the frequency of the a.c. source. Thus the starting voltage for the d.c. motor is controllably increased to its permanent value, which results in controlled increase of the d.c. motor speed up to its normal operating speed.

Title: Load controlled tandem axle - with load sensing control valve on tow bar through which axle pneumatic damper is filled
Inventor: SCHAEFFNER JOSEF
IPC: B60G17/04
Filed: 1973-09-25
Abstract: A simple tandem axle for large caravans etc. has both box axles sprung on trailing arms with the frong axle fitted with a pneumatic damper. The damper is connected to the tow bar by a line and has a pressure control valve at the far end. The tow bar is in two hinged parts with a spring loaded weight sensor to operate on the pressure control valve. This regulates the two bar weight by altering the suspension characteristics of the leading axle, when the control valve is connected to an air supply. This can be the air line at a garage. The system automatically sets the weight distribution of the two axles for a range of loadings of the trailer. The driver therefore requires no setting gauges etc.

Title: Identification of voice sounds - involves using characteristics recorded by test speaker for subsequent recognition
Inventor: SCHEFFLER GUENTER DIPL ING
IPC: G10L15/00
Filed: 1973-11-20
Abstract: The apparatus uses a method for the recognition of voice sounds spoken into a microphone and to a measuring set, and is operated so that each sound indicates a characteristic electrical quantity; the characteristics are recorded with a single speaker first pronouncing each of them for the purpose so that they may be recognised on subsequent occasions. The characteristic quality for each recorded sound may be shown on the screen of an oscilloscope, and an analogue or digital voltmeter or wattmeter may be used. The volume with which the word is spoken may be fixed, and a mask may be used to define the recorded word on the oscilloscope screen, and a photocell may be placed in front of the screen.

Title: Clutch actuated vehicle epicyclicccc ggeraarbox - has four friction clutches to give twwtevve twoo step don, one step up and direct ratios
Inventor: REPPERT RUDI
IPC: F16H3/66

Abstract: A four speed epicyclic gearbox utilises four friction clutch actuators for gear changing. The unit utilises a main input shaft carrying sun wheels and a planetary gear. A sun wheel is carried on the input shaft and is controlled by a clutch. Planetary gears mesh with annular gears that are controlled by clutches. First gear is effected by closing a clutch while all others are open, and the drive is then transmitted via the first stage. Second gear requires the next clutch to be actuated, while all others are open. Third gear provides a direct drive between the input and output shaft by actuation of the third clutch. The fourth gear provides a step-up ratio by closing the final clutch.

Title: Viscous damper for an indicating instrument - has circular discs with silicone oil filled separating gaps
Inventor: MATT ALFRED
IPC: F16F9/12
Filed: 1974-01-30
Abstract: The viscous damper is for damping out oscillations of the indicating pointer of an electrical measuring instrument. Small quantities of viscous liquid are used which reduce sealing problems and the contacting surface between the oscillating part and the damping liquid is increased. The degree of damping can be adjusted. The damping container has a fixed shaft and the bottom is covered with a layer of PTFE which prevents creep of the silicon oil. A solid disc is placed on this layer. Three further discs can rotate on the shaft. A fourth disc has carrier pins which project through the container lid through circular locks. These pins are connected to the mechanism subject to oscillations. PTFE collars are fitted on the pins to preven leakage of the silicon oil along the coupling pins. Balls are fited into grooves in the discs around the shaft which act as low friction bearings for the discs.
