Patent DE-3625765-A1 (DE)
Title: Coupling device for optical fibres
Inventor: STEIGER ERWIN
IPC: G02F1/335
Filed: 1986-07-30
Abstract: The invention relates to an optical coupling device having at least one cylindrical lens and having an acousto-optic cell. According to the invention, the acousto-optic cell is a substrate which is to be excited to form surface acoustic waves. These surface waves can be varied in frequency and amplitude in order to produce an optical grating structure. One end face of the cylindrical lens is bonded to the substrate outside an electrode structure provided for the purpose of generating the surface waves, and at least three optical fibres are fixed to the other end face of the cylindrical lens in such a way that these optical fibres lie with the optical axis of the cylindrical lens in a plane which is parallel to the direction of propagation of the surface waves.

Title: Apparatus for feeding sheet-like objects, which are lined up in the form of a stack on transport bars, to a singling station
Inventor: LOERSCH JOHANNES
IPC: G03D15/10
Filed: 1986-08-18
Abstract: An apparatus for feeding sheet-like objects, in particular slide frames or slide frame halves, which are lined up in the form of a stack on transport bars, to a singling station has a store station for accommodating a plurality of "full" transport bars. These can be transported cyclically in the store station to a delivery area above a singling station. A buffer station for accommodating an intermediate stack of sheet-like objects is provided between the singling station and the store station. It is advantageous that the feed of the transport bars and the removal of empty transport bars can take place independently of the singling operation. Owing to the buffer station provided, the singling operation can proceed continuously even during the changing of bars.

Title: Process and apparatus for the preparation of methyl formate
Inventor: BERTHOLD HANS DR
IPC: C07C69/06
Filed: 1986-12-16
Abstract: A large-industrial preparation of methyl formate from technical methanol by means of copper-containing catalysts failed until now in that the catalysts were deactivated even after a few hours and larger copper crystallites of only low activity were formed during regeneration ("calcination") by air and steam after heating to above 350@C. As a result of novel measures, the period of use and the regeneration of copper-containing catalysts should be improved. The process is carried out at a temperature of below 180@C, preferably using a copper/silica gel catalyst having a copper content of below 15%. The technical methanol is expediently predried. Regeneration of the catalyst can be carried out using a hot liquid solvent, in particular using methanol. The process can be carried out at elevated pressure, so that normal cooling water is sufficient for the condensation of the methyl formate. Requirements for industrial preparation are given therewith.

Abstract: The electrical plug connector for flat cables has three rows (A, B, C) of connecting contact elements (1) which are mounted at a specific distance from one another in retaining holes (20) in an elongated insulating material body (4). These connecting contact elements (1) are connected, in each case via a central connecting section (2), to insulation-piercing contact elements (3) which are at a different distance from one another than the connecting contact elements (1). One conductor (8) of the flat calbe (9) can in each case be pressed into the insulation-piercing contact elements (3), penetrating the insulation surrounding the conductor. A design which is particularly satisfactory structurally and functionally comprises insulation-piercing contact elements (3) which are distributed in two parallel rows which lie essentially in planes between the three planes which define the position of the three rows (A, B, C) of connecting contact elements (1). A box-shaped insulating material block (6), which is provided with perforations (7) for the insulation-piercing contact elements (3), can be inserted into a recess (5) which is formed out at the top in the insulating material body (4). Two channels (13, 14 and 34, 35 respectively) which are defined by the insulating material block (6) and the insulating material body (4) respectively, extend in the longitudinal direction and are separated from one another, are provided for accommodating the central connecting sections (2). <IMAGE>

Patent DE-3732150-A1 (DE)
Inventor: ALBRECHT THEODOR
IPC: A47B17/02
Filed: 1987-09-24
Abstract: A work table, in particular an office table, has a mechanism for adjusting the height and inclination of its top. With conventional adjustment mechanisms, the height and inclination of the table top are adjusted by raising or lowering it. Comfortable, simple, problem-free adjustment of the height and inclination of the table top (5) is achieved by a mechanism for adjusting the height and inclination of the table top (5) which is actuated by a control sequence, and by a switching or reversing system (39) for separate or simultaneous actuation of the height- and inclination-adjustment mechanism. Operation of a hand crank (75) permits simultaneous or selective control of the height- and/or inclination-adjustment mechanism, solely through a control axis (37) actuated by the hand crank. This work table is particularly useful as an office table.

Title: Electronic multiplier
Inventor: FOERDER WALTER DIPL ING
IPC: G06J1/00
Filed: 1987-12-18
Abstract: In a known electronic multiplier, the input quantities are fed, displaced in time, via an amplifier with an alterable amplification factor to an analog-to-digital converter. A microcomputer multiplies the digitally coded values which correspond to the input quantities (E1, E2). The object of the invention is to implement a cost-effective multiplication of two input quantities. To achieve the object, at the start of each clock cycle, in a scanning stage, a first input quantity (E1) is captured by the analog-to-digital converter (1). During the further clock cycle, in an evaluation stage, the bit sequence which corresponds to the first input quantity (E1) is output serially by the analog-to-digital converter (1). During each evaluation stage, as each bit is output by the analog-to-digital converter (1), a second input quantity (E2) is multiplied in an evaluation circuit (4) by a factor which corresponds to the significance of the bit, and fed to an integrator (5) if the current bit is high. <IMAGE>

Patent DE-3807640-A1 (DE)
Title: Contactless aerosol seal
Inventor: HAEUSLER MARIO
IPC: F16J15/40
Filed: 1988-03-09
Abstract: The invention relates to a contactless aerosol seal between two gas spaces and having a shaft penetration, the seal being designed as a radial compressor, the pressure side of which is on the same side as the aerosol source. While, because of their relatively high inertia, solid and liquid aerosol particles are retained in the aerosol-containing gas space, the aerosol-free gas can flow between the gas spaces and also counter to the direction of delivery of the radial compressor. This seal without an auxiliary medium thus remains effective even when there is a drop in the rotational speed of the shaft penetration owing to operating conditions.

Title: Mobile drilling rig
IPC: E21B7/02
Filed: 1988-03-22
Abstract: In a mobile drilling rig, the vehicle of which has a top part resting on a bottom part via a slewing-ring part (38), a reversing valve (130) is provided in the vehicle bottom part. The reversing valve (130) disconnects a travel-gear hydraulic motor (28) from a hydraulic circuit of the vehicle and connects all consumers of the casing machine to this hydraulic circuit. To distribute the total volume of pressure medium in this hydraulic circuit over working cylinders (78-86) for lifting and lowering the clamping jaws of the casing machine and over hydraulic cylinders (104, 106) for rotating a casing string clamped in these clamping jaws, a controllable volume distributor (134, 158) is provided which makes available the total volume of pressure medium for the rotation of the casing string when no compressive or tensile force has to be exerted on the casing string. <IMAGE>
