Patent DE-4016527-A1 (DE)
Title: Four-jaw chuck with clamping force equalisation - has differential gear system to connect jaws and equalise clamping force
Inventor: LAUBE RUDOLF
IPC: B23B31/169
Filed: 1990-05-22
Abstract: Conventional four-jaw chucks used to clamp rectangular and irregular shaped parts have independent actuation of the jaws so that uniform clamping cannot be guaranteed.  Two pairs of jaws are connected through a pair of bevel gears (4, 5), and pinions (22) fixed in a bell housing (9) which can be rotated relative to the chuck body by means of a screw and rack (2, 3). Each bevel gear has a radial slide guiding the movement of a jaw pair. The bevel gear system acts as a differential: both bevels rotate together and move all the jaws inwards until one jaw pair meets resistance; the bevel gears then rotate relative to each other and the other jaw pair moves up rapidly until all four jaws are clamping the work with equal force. ADVANTAGE - Uniform clamping of work. Design is simple and uses readily available components.

Filed: 1990-07-10
Abstract: An injection molding system having at least one insulation gate seal (12) extending outwardly to bridge an insulative air space (34) between a heated nozzle (10) and the adjacent cooled cavity plate (22). Each seal (12) has a central bore (36) therethrough to convey pressurized melt from the nozzle to the aligned gate (42).

Title: Monitoring potential between sacrificial anode and steel reinforcement - monitoring change in potential between reference electrode and either anode or steel when pulsed current is applied, avoiding short circuit
Inventor: KOTOWSKI STEPHAN DR
IPC: G01R31/02
Filed: 1990-08-11
Abstract: Monitoring the potential between a sacrificial anode and the steel reinforcement during the placing of the anode in setting reinforced concrete consists of placing also a reference electrode (17) inside the concrete and applying a current pulse between the anode (6) and steel reinforcement (5). The continual potential difference change between reference electrode (17) and anode (6) or steel (5) is measured and when potential of the reference electorde falls to the potential which existed prior to applying the current pulse within a predetermined time interval a short circuit signal is given off. When a potential charge of 0-15% is recorded between reference electrode and steel reinforcement a short circuit signal is given off. The predetermined time over which the potential falls is 1.5-5 sec. and the ratio between duration of current pulse and predetermined time interval is 0.5:1 to 2:1. Sacrificial anodes may be treated one to each mesh or reinforcement. ADVANTAGE - Avoids any short circuiting between the electrodes during concrete setting.

Filed: 1991-04-12
Abstract: From a sequence of programme parts in a provisional layout, subsequences are examined, varied and the best possible determined with respect to a gain in the use of a cache memory on which the progress of the programme depends. Continued division of the subsequences enables the gain to be further increased. When a stage is reached at which further subdivision no longer gives useful results, long subsequences are once again examined, varied and the best possible determined and then again subdivided, etc., thus enabling the gain to be even further increased.

Abstract: The multi-purpose food processor (3) consists of an electric motor (11) via whose drive shaft (10) two output shafts (15, 37) are driven, which are mounted in one axis (52) and rotate at different speeds. Both the drive shaft (10) and the two output shafts (15, 37) have appropriate pulleys (8, 56) which are in rotary connection in each case via a belt (14, 44). The two output shafts (15, 37) are mounted on a common axis (52).

In this case, the belt tension between the drive shaft (10) and the second output shaft (37) is effected by a belt tensioner (26) which deflects the guiding of the second belt. In this case, the length of the second belt (44) is dimensioned such that, after adjustment of the belt tension of the first belt (14), the tension of the second belt (44) can be effected by a movement within its operating range and subsequent fixing of the belt tensioner (26). <IMAGE>

Abstract: The sensor comprises a movable sensing element which is at least partially immersed within the fluid flowing through the pipeline, two electric coils for detecting movement of the sensing element as a result of a displacement due to the flow of fluid; and an electrical means for generating an electric signal representative of the detected fluid in response to the detected movement of the sensing element. in a preferred embodiment of the present invention the sensing element comprises a plate of non-magnetic material supported within a housing structure for oscillatory movement. The sensing element further comprises a head member attached to one end of the plate which is formed from a magnetic material such as a ferromagnetic material or a permanent magnet.
