Patent DE-2711638-A1 (DE)
Title: Wall mounted branch connection support - has bracket fixed to wall and provided with slidable arms
Inventor: COME PHILIPPE
IPC: F16M13/00
Filed: 1977-03-17
Abstract: The support is for branch connections for water, electricity etc. particularly with a meter. It has a bracket for fixing to the wall and arms extend forward from the support. The geometry of the support is adjustable in two dimensions, the arms sliding in or on the bracket. The item to be supported is fixed to the arms clear of the plane formed by them with the bracket by means of components sliding along the arms. The components can also be arranged to slide in a plane different to that by the arms and brackets, thus giving adjustment in a third dimension.

Title: Vibration polishing machine with ring shaped container - which is mounted on elastomer pads and driven by eccentric about centre
Inventor: RAMPE JOHN F
IPC: B24B31/073
Filed: 1977-08-11
Abstract: The tray (20) in which the parts to be polished, together with the abrasive particles, are placed is ring shaped. The tray is attached to the machine frame (12) by a number of elastomer mounting parts (16). A drive arrangement (176) imparts the vibratory movement to the tray, and the drive is such, that the tray moves mainly around a centre point (34). The elastomer mounting parts are so arranged, that the axes of these parts cut one another in the centre points. Each elastomer mount is attached to frame and tray by pads which determine the centreline of the mounting. The movement of the tray imparts a shear load on the elastomer mounts. The centrelines of the elastomer mounts lie in a horizontal plane which passes through the centre point.

Title: Ski braking device - has double-armed brake stirrup with arms tilted about axis at right angles to longitudinal direction of ski
Inventor: BIELER HANS
IPC: A63C7/10
Filed: 1978-01-12
Abstract: The arms are tilted into the braking position by the action of a spring, in which position the ends of the arms on one side of the axis project downwardly into the surface over which the ski is running. The ends of the arms on the other side of the axis, which are joined together and are pressed down by the ski boot, are tilted upwardly after separation of the ski boot from the ski. The spring for tilting the stirrup is tensioned between the connected ends of the arms and a mounting plate, defining a line of action extending substantially through the axis in the inoperative position. A leaf spring engages with the stirrup to initiate operation of the device by the spring.

Title: Underground heat store using solar heat - uses second coil inside main coil as heat exchanger for hot water supply
Inventor: HANSEN UWE
IPC: F28D20/00
Filed: 1978-03-16

Title: Spring balance correction device - compensates for gravitational acceleration variations using horizontal bending spring of adjustable effective length
Inventor: SCHWARZ JOSEF
IPC: G01G3/18
Filed: 1978-07-28
Abstract: The spring balance correction device compensates for the effect on the balance of variations in the acceleration due to gravity. It has a simpler construction than conventional devices and enables exact correction of the error without making the spring balance operation position dependent. A fixed essentially horizontal bending spring (13) has a spring constant relatively small compared to that of the weighing spring. Its free end projects into the path of motion of a perpendicularly moving balance part against which it rests along the whole path of motion. The effective length of the bending spring is adjustable.

Title: Digital receiver for time multiplexed digital exchange - initiates synchronisation process when consecutive synchronisation words occur at wrong instants
Inventor: WINTZER KLAUS
IPC: H04Q11/04
Filed: 1978-08-10
Abstract: The digital receiver detects the appearance of a sync. word prefixed to each signal block and thereby ensures synchronised reception despite lines of different lengths. A counter is started at the beginning of the receiver's received time-window. The count that this counter has reached at the moment the sync. word is detected is stored and used in the next receive time-window as a reference fo comparing with a new count. If consecutive counts are not the same the synchronisation process is initiated.

Title: Sensor for rotary movement acceleration - has object with projections in case, so that when case is rotated, it lags behind and closes circuit through contacts
Inventor: SVENSSON LARS GOERAN
IPC: H01H35/06
Filed: 1978-09-18
Abstract: The sensor has a case (1) with an inner space (2) through which a flowing medium flows and acts on an object (3) with radial projections (4), supported by a bearing at its centre of gravity. The object is controlled by a spiral spring device (5) which tends to hold it in a certain position w.r.t. the case. The object centre is connected to a circuit whose other end is connected to contacts (6) in the case wall, so that when the case is rotated by a certain angle, the object lags behind owing to its inertia, and its projections (4) touch the contact (6) and close the circuit.

Title: Textile industry fibre seed and length measurement - by removing electrostatic charge and measuring current and total charge
Inventor: PFEIFFER NORBERT
IPC: G01P3/66
Filed: 1979-04-10
Abstract: An electrostatic speed and length measurement technique is applicable to non-conducting objects such as fibres on winding machinery in the textile industry. It is an almost contactless technique eliminating mechanical measurement components and giving accurate measurement results in the presence of high speeds and rapid changes of speed. An electrostatic charge is applied to the moving object using the dielectric displacement between it and another insulator. The charge is then transported by the measurement object until removed and measured as an observable electrical current. The magnitude of the measured current is a function of the object speed. The total charge received from the object by the measurement system is stored to give a measure of the length of fibre.
Patent DE-2915957-A1 (DE)
Title: Surface tension or fluid concn. measurement method - exploits drop rate of fluid through capillary tube and computes required values from temp. measurements
Inventor: KNOLL ANTON
IPC: G01N13/02
Filed: 1979-04-20
Abstract: Fluid is introduced into a fork shaped tube (2, 2') and drips out of a capillary tube (4) at the bottom. The drops are recorded by a pair of sensing electrodes if the fluid is conductive or else by an optical sensor, and the drop rate is a function of the surface tension. For conducting fluids, a contact electrode (7) towards the bottom completes a circuit with two other electrodes (5, 6) at different levels in the two upper arms of the fork to indicate when to start and when to stop counting the drops. Measurement of temperature also enables concentration to be computed.
Patent DE-2916961-A1 (DE)
Title: Coupler decoupler for multimode optical fibres - has connecting element for thin-sheathed fibres with coplanar axes, and aligned at coupling point
Inventor: WITTE HANS-HERMANN DIPL PHYS D
IPC: G02B6/28
Filed: 1979-04-26
Abstract: A single conducting fibre (1) butts against two connecting fibres (2, 3) at the coupling position (5), at the other end of the connecting fibres are located a continuation fibre (4) and a decoupling fibre (5), these fibres and the conducting one having relatively thin sheaths (11, 41, 51), but the connecting fibres being formed solely by the cores. The whole coupler is affixed to a substrate, the individual fibres being secured by fasteners (7, 8). The axes of the connecting fibres are in the same plane as that of the incoming sheathed fibre. The diameter of the connecting fibres is the same as that of the core diameter of the conducting and (de)coupling fibres. This type of (de)coupler reduces the insertion losses, and expands the operating range without limiting its use to one branch only.
Patent DE-2916989-A1 (DE)
Title: Motorised nail file shaping unit - has endless loop driven round concave curve with filing surface inside
Inventor: RADLMEIER SIEGFRIED
IPC: A45D29/05
Filed: 1979-04-26
Abstract: The nail file includes a closed strip-like member (6) which forms a loop guided on a frame (4) by two guides. The side of the file element (6) facing the inside of the loop has a roughened surface (12) so that now when switching on the motor which drives the loop the finger nail can be brought into contact with the file from the inside of the loop and moved about to obtain the correct filed shape. By applying the roughened filing surface to the inside surface of the loop, means that at least in the corners there is a concave curvature which makes filing finger nails much easier.
