Title: Overload protection system for vehicle lifting platform - uses load measuring devices connected to adder and equaliser stages to give alarm
Inventor: SCHLOTTERMUELLER PETER
IPC: B66F17/00
Filed: 1979-09-18
Abstract: The lifting platform for motor vehicle repair and inspection, has two parallel arms each with a support member which can slide outwards or inwards. Incorporated in each support member, or mounted underneath it, is a load measuring device which gives signals for an overload protection system. When an excess load is aoplied, a warning and/or a braking device is operated. The load measuring devices are connected to an adding stage to operate an indicator. The adding stage can be followed by an equaliser which supplies a singal proportional to the permissible loading to a memory. The system can use a double adding arrangement using comparators and adjustable potentiometers.

Title: Partitioning screen across mine gallery - has mats joined into units of gallery width braced cross-ways with support structure
Inventor: ALBERS KARL
IPC: E21F17/103
Filed: 1979-12-12
Abstract: A supporting scaffolding-type framework is erected. It has a sheet of plastics or textiles stretched over it, in setting up partitions transversely to a gallery, esp. for sealing off sectors in underground mining. A series of warping mats are joined together, via connectors transmitting high tensile forces, to form mat strands as long as the width of the gallery. They are set one on top of another, and braced with the gallery support system, transversely to the gallery axis. This is rapid and stable, and suitable for ventilation screening or as damming abutment.

Title: Linear speed transducer for disc head controller - subtracts noise components of two induced coil movement signals
Inventor: HERTERICH FRIEDRICH R
IPC: G01D3/028
Filed: 1980-03-27
Abstract: A linear speed transducer converts a linear mechanical motion into an electrical signal and is applicable to stabilised control of a magnetic recording disc head movement. It is an improvement on conventional moving magnet devices in that it is less sensitive to disturbances and stray fields but more sensitive to movement. A permanent magnet (74) and pole piece (76, 78) arrangement generates two electrical signals in coils (92, 94) wound on the pole pieces. Each signal corresponds to movement generated induction and consists of two components. One component of each signal is related to meachnical motion and the other component to electrical and mechanical disturbance fields. The signals are combined so as to add together the movement related components and subtract the noise components.

Title: Driving metal nuts or bushing into wood or plastics - involves centering and holding driving, and pneumatic or hydraulic tool return force
Inventor: BEER HERBERT
IPC: B27M3/00
Filed: 1980-04-11
Abstract: Provision is made for driving relatively hard, pref. metal, components, incorporating a hole or depression, in softer, pref. wooden or plastic accommodating pieces, using a pressure-medium- activated device - such as nuts or sockets onto a chair seat. The component (4) being inserted is first centered, by engagement in the hole (8) and held to prevent displacement or tilting. Driving-in then proceeds, with position retained. Components are finally released, and the activating device is returned to its initial position. This can comprise two working parts. One (10) such as a pin fitting the hole and the other (11) round it fitting the component being driven in with time control. This ensures firm driving, without risk of slipping.
Patent DE-3014407-A1 (DE)
Title: Image and light conducting optical fibre bundle - has reticulated covering on each individual core to increase internal reflection by providing numerous reflecting surfaces
Inventor: KUBOTA TETSUMARU
IPC: G02B6/06
Filed: 1980-04-11
Abstract: The cover (24) of each individual core (23) is made of crown glass and is so formed to have a finely reticulated surface consisting of numerous projections (27) and depressions (26). When a light beam (I1) enters the end of a fibre (25) and arrives at the boundary (29) between core (23) and cover (24) with an angle of incidence which is not smaller than the critical angle for core (23) and cover (24), total internal reflection takes place and the light beam (I1) finally emerges from the other end of the core (23). When a light beam (I2) enters at an angle which is less than the critical angle it is partly reflected at the boundary (29) and partly enters the covering (24) as (I3) where it strikes the reticulated surface (25) and is reflected (I4) back into the core (23). Reflectivity between the cores is lessened without significantly increasing their external diameters thus has advantages for use in endoscopes.

Title: Slide magazine for semi-automatic slide mounter - has catch to inhibit process if slide mount stack at minimum level
Inventor: EUTENEUER CHARLES L
IPC: G03D15/10
Filed: 1980-06-06
Abstract: The semi-automatic slide mounter has a magazine loading for the slide frames and a hand lever operation. The magazine stack is divided into upper- and lower- stacks to ensure that only a limited weight is applied to the slider mechanism at the bottom of the magazine. The upper stack rests on a screw head attached to a reciprocating drive linked to the operating linkage to drop a fresh mount onto the bottom stack at every cycle. A safety catch blocks the linkage if the top stack is empty. The top stack is also located on a central core for accurate alignment with the feed funnel and the retaining screw mechanism is held into position by an angled spring.

Title: Excavator inclination angle measurement system - uses small pendulum deflections with oscillation damper and rapid-action transducer linkage
Inventor: RADOSZ BRONISLAW
IPC: G01C9/12
Filed: 1980-06-19
Abstract: The appts. is used for measuring the angle of inclination of an excavator and uses a pendulum fixed to a rotating arm on the excavator. The deflection of the pendulum is transferred to a measurement and display unit. It is constructed so that only small angles of inclination occur and the measurement relative error is less than 3%. The effects of strong vibrations are eliminated. Pendulum oscillations are damped and transduced into an alternating current. The alternating current is then rectified and averaged before the mean value is input to the measurement and warning device which responds to a signal corresponding to a given inclination angle. The pendulum is connected to an angular position transducer via a rapid-action drive.

Patent DE-3110001-A1 (DE)
Title: Arcuate frame
IPC: B29C63/00
Filed: 1981-03-12
Abstract: Arcuate frames comprising a hollow plastic profile (6) are used principally as frames for windows or doors. It is thus necessary, for reasons of stability, to provide, within the hollow plastic profile (6), a reinforcing profile which likewise must have an arcuate progression. In order to achieve particularly good values of stability and thus a sufficient degree of sealing of the frame, the reinforcing profile is designed as a continuous, hollow metal profile in the form of a box-shaped tube (8). For the production of an arched window frame (4), the continuous, hollow box-shaped tube (8) is first of all deformed to give the desired arch. Subsequently, the hollow plastic profile is heated until it is in a deformable, soft state, and the soft hollow plastic profile (6) is then drawn onto the deformed box-shaped tube (8). <IMAGE>
