Abstract: A solid rod-shaped laser medium is mounted in one centre axis of the hollow mirror, together with a rod-shaped excitation light source. The hollow mirror pumping system is divided into two compartments by a partition in one centre axis, both compartments being supplied with a coolant. The partition (4) is mounted on the same centre axis as the laser medium (2) and the excitation light source (3). Between the partition and the laser medium on one side and the excitation light source on the other side are gaps (7, 8, 9, 10).

Inventor: MAYER NORMAN
IPC: G01R1/067
Filed: 1976-03-31
Abstract: An electromagnetic and pneumatic mechanism controls an array of test probes in an automatic electronic circuit testing machine. An array of probes is brought into contact with the required points on the test circuit by pneumatically driven spring mounted pistons. The mechanism consists of three blocks (6) held together by screws (10) and containing respectively an array of electromagnets (7), pneumatic valves (8) and pneumatic cylinders with spring (12) mounted pistons (9). A printed circuit board (20) is mounted below the bottom block and the piston driven test probes (3) protrude through this to make contact, when the electromagnets (7), valves (8) and pistons (9) are actuated, with the circuit (4) under test. Flexible contacts (19) between the test probes (3) and the mechanism printed circuit (20) and a supply cable (22) to that printed circuit are provided.

Title: Controlling particle size produced by mineral crusher - by adjusting crusher tilt and altering speed of rotation
Inventor: BROMAN JOHN SAMUEL
IPC: B02C25/00
Filed: 1976-04-13
Abstract: The crushing roller (3) works in a rotating hollow cup (1) which has an oulet (5) centrally at the bottom, and at an angle to the vertical. The time during which material remains in the crusher is to be controlled by varying both its speed of rotation and the inclination (V2) of its axis to the vertical. Crushed material which reaches the higher-lying side of the cup falls under gravity towards the exit but is also lifted by the centrifugal force the rotation induces. The balance of these two opposed forces is adjusted to give a produce of the required grade.

Title: Variable reaction for brake pedal - has adjustable friction drag element to allow accurate operation of retarder microswitches
Inventor: VOLLMER OTTO
IPC: B60T7/04
Filed: 1976-05-06
Abstract: The brake pedal operates on the brake linkage via an adjustable drag friction element. This enables the driver to adjust the setting of the pedal to a fine control, before the wheel brakes engage. Micro-switches on the pedal operate in sequence to control the increasing braking from retarders. The small movements of the pedal on the microswitches can thus be closely controlled, with an increasing resistance from the drag element. Elastic ratchet points can reinforce the setting of the microswitches.

Title: Load regulated dual circuit brake - has variable pivot balance lever moved by servo motor between circuit pistons
Inventor: VOIGT DIETER
IPC: B60T8/18
Filed: 1976-05-25
Abstract: The multi-axled hydraulic or pneumatic brakes are operated as a dual circuit by a tandem master brake cylinder with the relative pressure on the two pistons operated by a balance lever. The manual input force on the lever is on a movable pivot so that the relative forces to the two circuits are controlled by the position of the pivot, in relation to the relative loadings of the axles. The system provides optimum braking w.r.t. static and dynamic loading. The pivot point is moved by a servo motor.
Patent DE-2626034-A1 (DE)
Title: Switching modulator with differential amplifier - has two switches controlled in opposite phases by binary carrier signal
Inventor: BURGER ERICH
IPC: H03C1/58
Filed: 1976-06-10
Abstract: The modulator modulates an input signal with a binary carrier signal, and has a differential amplifier with an inverting and a non-inverting inputs. The input signal is applied to the non-inverting input through a voltage divider. Input signal is applied through a series resistor, and output signal through a negative feed-back resistor to the inverting input. A first switch is controlled by the carrier signal, so that, depending on the carrier signal binary values, it delivers as output signal the input signal or the inverted input signal. The first switch (SW1) is inserted between the series resistor (R1) and the differential amplifier (V) inverting input (E1). The switch is conducting or blocked when the carrier signal (TR) has a first or the second binary value ("0" or "1"). The resistor (R2) has one terminal connected to the reference voltage (OV), and the other to a second switch (SW2) controlled by the carrier (TR) and connected to the inverting input (E1). This switch is operated in opposite phase to the first (SW1).

Title: Pipe seal for accommodating misalignments - has resilient ring of non-uniform section providing sealing and overload support
Inventor: BRAM GEORGES EUGENE
IPC: F16L21/03
Filed: 1976-10-28
Abstract: The pipe seal comprises a resilient element situated in a groove in the inner surface of an outer pipe end (E) and engages a smooth cylindrical outer surface of an inner pipe end. The element is a ring whose cross-section, when free, is flat (5) with a bulbous enlargement (4) at one end. When the inner pipe end is inserted into the seal, it slides past the flat portion with a clearance (8) and then compresses the bulbous portion. Sealing is effected by the compressed bulbous portion, the flat portion providing back-up support in case of overload or misalignment of the pipes.

Title: Relative density control of liquid-solid mixts. - esp. for hydraulic transportation, by weighing loaded metering container
Inventor: BUESE FERDINAND DR
IPC: B65G53/30
Filed: 1977-01-08
Abstract: Controlling the relative density of a mixt. of a liquid with solid matter is partic. applicable to vertical hydraulic transport using a tube chamber. Before the mixt. is transferred to the feeder for the transport system, a predetermined relative density of the mixt. is achieved in an intermittently working feeder container. This has solid matter and fluid feeds together with an overflow. Its volume corresponds to the capacity of a tube chamber and as it is filled it is weighed. An undisturbed operation of the vertical hydraulic transport is ensured by supervision and control of the relative density of the solid matter and fluid mixt. which is simple to carry out technically, is relatively cheap and guarantees optimal transporting capacity.

Title: Automatic cutter control network - minimises cut track separation on record discs according to signal amplitude and previous track width
Inventor: KERN OTMAR
IPC: G11B3/00
Filed: 1977-03-03
Abstract: A control network is used for minimizing the track separation on recording discs being cut on a disc cutting machine. It uses the signal amplitude and previous track width to offset the current position of the cutting head. The control network uses the present signal modulation amplitude neighborhood, the previously cut track modulation and a minimum track offset threshold signal to control the present track offset position. The network comprises a comparator amplifier, comparator, gate difference amplifier analogue switch, counter, impedance matching circuit and feedback integrator. The control network is essentially analogue, and is controlled by a common synchronising clock signal. A similar, but essentially digital control network is also possible.
