Title: Pull-in device for microfilm cassettes
Inventor: JAEGER GUENTER
IPC: G03B23/02
Filed: 1985-07-19
Abstract: The invention relates to a pull-in device for microfilms on a microfilm projector. In order to be able to pull microfilms stored in a cassette mechanically into the microfilm projector with as little outlay as possible, the cassette consists of pivotably mounted plates 17-21 which are stacked one above the other in the manner of a book and between which a microfilm 12-16 is stored in each case. In order to be able to turn up the plates 17-21 by direct access, there is provided on each plate a contact surface 23-27 for a plunger 28, which can be freely accessed from the remaining plates. The exposed microfilm is pulled in by means of a friction roller 31, which can be pivoted over the microfilm. <IMAGE>

Title: Lightweight warehouse and erection method therefor
IPC: E04C3/40
Filed: 1985-07-20
Abstract: The invention relates to a temporarily erectable lightweight warehouse having truss beams and profile sheets. Each truss beam comprises a horizontal rectangular-tube roof part and two vertical rectangular-tube side parts. The roof part and the side parts are connected to one another at the eaves by means of plug-in curved pieces. The profile sheets are trapezoidal sheets which extend with their trapezoidal beads in the longitudinal direction of the warehouse and are clamped tight above the truss beams by means of tightening straps. The lower ends of the truss beams are placed on holding pins which are fastened at predetermined intervals on U-profile sections which extend horizontally in the longitudinal direction of the warehouse. The trapezoidal sheets can be transported rolled up and during assembly can be unrolled from the top to the sides over the previously erected truss beams.

Title: Splash-guard device on spectacle-glass edge-grinding machines
IPC: B24B55/04
Filed: 1985-07-31
Abstract: The invention relates to a splash-guard device on spectacle-glass edge-grinding machines with a grinding wheel mounted in the machine lower part and with a machine upper part which carries the spectacle glass between two coaxial half-shafts, can pivot up and down about a horizontal axis, is adjustable during grinding and which consists of a hood covering the glass and the grinding wheel during the grinding operation. A reliable covering of the grinding wheel and of the spectacle glass is to be achieved by constructively simple and easily operable means. For this purpose, the box-shaped hood (9) is arranged on the machine lower part (1) so as to be pivotable about an axis (19) parallel to the grinding-wheel axis, and the side walls (13, 44) of the box-shaped hood (9) have slots (20), through which the half-shafts (6, 7) pass in order to hold the spectacle glass (B). <IMAGE>

Patent DE-3531976-A1 (DE)
Title: Transmission mechanism between the measuring system and the measuring mechanism of a rotary viscometer
Inventor: REINHOLD UWE DIPL PHYS
IPC: G01N11/14
Filed: 1985-09-07
Abstract: The transmission mechanism according to the invention is to provide a higher accuracy in the measurement of viscosity than was possible hitherto, without requiring increased outlay in its manufacture. The transmission mechanism is to be designed in such a way that the measuring temperature and the substance to be measured should not affect the transmission mechanism, which should always have a stable axial position. In order to achieve this, the transmission mechanism is suspended by a central section via a first torsion member, so as to be resilient with respect to an imaginary longitudinal axis and to be rotatable thereon, from a torsion-proof spring attached to the measuring-mechanism housing, and is linked to a second torsion member which is supported in an inner chamber of the central section and is likewise located on the imaginary longitudinal axis. In the lower part of the central section a detachable clutch is provided which accommodates a shaft positioned on the imaginary longitudinal axis and linked to a section of the measuring system. Arranged in the upper part of the central section there is a capacitor appertaining to the measuring mechanism. The interior of the measuring-mechanism housing is sealed externally by a labyrinth seal.

Title: Muscle-powered vehicle with balanced pendulum drive
Inventor: BECKER FRITZ DIPL ING
IPC: B62M1/20
Filed: 1985-09-26
Abstract: In the case of muscle-powered vehicles which transmit arm and leg power to levers going to and fro, i.e. oscillating, the problem arises that the delivery of power is unequal. By vertical displacement of the seat the invention to be protected ensures that in every high-power movement phase the driver builds up potential energy which is released in the following, low-power phase.   In this manner, human muscle power may not only be used to the greatest possible extent for locomotion, but the invention also ensures that the delivery of power is even which, due to ergonomics, is otherwise not possible.

Patent DE-3633979-A1 (DE)
Title: Transport mechanism with chain drive and endless chain
Inventor: DIETZE ROLF
IPC: B23Q7/14
Filed: 1986-10-06
Abstract: The invention can be used to move pallets or the like by means of a chain drive into an end position in which a stop comes into effect. The chain drive has sprockets which are arranged at four corner points and over which an endless chain is run. The chain has at least one flight which engages in a link fastened to the respective pallet.   The aim of the invention is for the pallet, after automatic transport into its end position is complete, to also be automatically placed against the existing stop free of play. The object of the invention is to create a transport mechanism according to the field of application in which the transport drive is utilised for removing the play. To this end, in each case the short chain strand which lies near the stop is inclined so that the flight first places the pallet against the stop on the path of this strand and, on its further path along the inclinations, it presses the pallet by means of a resilient link wall against the stop. <IMAGE>

Filed: 1987-04-27
Abstract: An anchor member assembly is made up of an anchor bolt and an expansion wedge. The assembly can be anchored in a borehole in a receiving material by inserting the assembly and then displacing the expansion wedge relative to a wedge surface on the anchor bolt. At its trailing end, the anchor bolt has an axially extending outwardly flaring head section forming at least a part of a conical surface. The head section can be driven by hammer blows into a wooden member. Initially, the anchor bolt and expansion wedge are in detachable engagement until the head section is driven into the wooden member. Subsequently, as the expansion wedge is axially displaced relative to the anchor bolt, the engagement between them is released and the anchor member assembly is secured in the receiving material.
