Patent DE-2644605-A1 (DE)
Title: Twin turbocharged V=formation engine - controls fuel injection pump output as function of pressure in cylinders at lowest charge pressure
Inventor: FRAENKLE GERHARD DIPL ING
IPC: F02D23/02
Filed: 1976-10-02
Abstract: The fuel injection engine has at least two sets of cylinders (1, 2) which may be arranged in V - formation, each set having a turbo-charger. There is a single fuel injection pump (3) whose output is controlled (4) as a function of the charging pressure via a connection (5) leading from one of the sets (1). A further line (6) from the other set (2) of cylinders is connected to the first line (5) via a control slide valve (7), the arrangement being such that only the lowest of the available charging pressure is admitted to the pump control and the fuel output thus correspondingly reduced, so that% in the event of turbocharger failure, no engine overheating occurs.

Title: Self aligning sliding element bearing - has spherically seated ring with radial pin to prevent rotation of ring
Inventor: BOESIGER HANS
IPC: F16C23/04
Filed: 1976-10-26
Abstract: The self-aligning sliding element bearing comprises a ring (1) having a spherical outer surface seated in a spherical inner surface of a supporting housing (2). The ring supports a shaft for rotation and is itself pivotal in the spherical inner surface. To prevent the ring participating in the rotation of the shaft, a radial pin (4) secured to the housing engages a groove (3e provided in the outer surface of the ring. The groove lies in the plane including the ring axis so that the pivoting of the ring is not inhibited.

Title: System confirming authenticity of identity card holder - reads data from card and processes secret data fed in from holder to produce signal if true owner has card
Inventor: KINKER DONALD ERNEST
IPC: G07F7/10
Filed: 1977-02-14
Abstract: The card carries mechanically readable data, and the test is in an on-line system with a central computer and at least one distant terminal with a card reading device and a keyboard. Data are read from the card. A first signal is generated, representing the data read from the card. A second signal is generated by the keyboard representing secret data fed by the card holder. The correct data are known only to the rightful owner. The second signal is converted in two parts, the first signal is converted into a first converted signal without any logical connection with the first signal. The converted first signal is compared at the distant terminal with the first signal part, and if the result is positive the second signal part is transmitted to the central computer which compares it with a reference signal. If the result is positive, a signal is generated which declares the holder to be the rightful owner.

Title: Work table height adjustment fitting - has sheet metal plates with bearing blocks inside housings on table legs
Inventor: HECKMANN PETER
IPC: A47B9/06
Filed: 1977-05-18
Abstract: The table top is supported on the free ends of two parallel square-section tubes (20) which move vertically in guides in housings (5) built into the table legs. These each contain two parallel facing stamped sheet metal plates (11). These plates have punched-out sockets (14) for bearing blocks (12) which in the area between the metal plates form the slide faces (13) which adjoin the outer sides of the tubes (20). The use of the metal plates allows the bearing blocks to be fitted with a high degree of accuracy so that the tubes which form the volumns can be aligned and connected together with precision even if there is a slight difference in the measurements. The bearing blocks preferably have screwed-on pins for insertion into the sockets of the metal plates. The bearing blocks can thus be used directly as the spacers for the two plates.

Title: Continuous contact plater with absorbent roller - in fluid contact with electroplating bath for controlled plating on discrete areas
Inventor: EIDSCHUN CHARLES DOUGLAS
IPC: C25D5/06
Filed: 1977-09-23
Abstract: Contacts having curvilinear contact points are continuously electroplated by engaging the contact points with a roller having an absorbent peripheral surface which is in fluid contact relationship with an electroplating bath. The roller is positioned in axial parallel relationship to the aligned contact points. The contact points are moved along an axis parallel to the roller axis while the roller is rotated so that the contacts trace a helical path on the roller surface. The contact points are electrically energised as the cathode and the electrolytic soln. and absorbent portion of the roller are electrically energised as an anode. Used for continuous contact electroplating, e.g. with gold. A consistent amount of fluid is applied on the roller surface and the bath is maintained to constantly wet the roller surface in a controllable electrodeposition quantity. A contact point can be plated in the curvilinear portion without plating the near portion or other portions which have no electrical relationship in a circuit. This presents considerable savings in plating material.

Title: Benzyl alcohol prepn. from benzyl halide - by reacting with alkali formate and then with alcohol
Inventor: BERNHARDT GUENTHER DIPL CHEM D
IPC: C07C67/03
Filed: 1977-12-31
Abstract: Benzyl alcohol opt. substd. on the ring is prepd. by reacting benzyl chloride and/or bromide, opt. substd. on the ring, with an alkali(ne earth) metal formate in the presence of a catalyst and then reacting the benzyl formate formed with an alcohol to cause transesterification, in the presence of a catalyst. Transesterification is pref. effected without a solvent at a temp. at which the benzyl halide is in the liquid phase. Reaction of the benzyl halide with the metal formate takes place directly in the bulk so that the reaction volume in the reactor is used its optimum. Reaction occurs at normal pressure with high yields of benzyl formate. The inorganic halide formed as by-prod. is easily separated from the benzyl formates. The benzyl alcohols are obtd. as such or as very conc. solns. in alcohol and can be isolated simply.
