Title: Drilling device for making cylindrical drill holes in steel-reinforced masonry or masonry penetrated by metal parts
Inventor: FISCHER ARTUR PROF DR
IPC: B28D1/14
Filed: 1989-03-25
Abstract: Drilling devices for making cylindrical drill holes are known. To make cylindrical drill holes in masonry with steel reinforcement, a drilling device is proposed on whose drilling shank there is formed a bulge which permits deflection of the drilling head upon striking a metal part in the masonry. The drilling process can therefore be continued despite the drilling head striking a metal part situated in the masonry, in that the drilling shank is guided past the metallic obstacle.

Abstract: The reaction product in vapour form of the continuous reaction of C3-C4-monoalkanols with hydrogen chloride is discharged, condensed and separated into a light organic phase and a heavy aqueous phase. The heavy aqueous phase is distilled directly, the bottom product obtained is the HCl-containing water of reaction and the top product is an alcohol stream which is returned to the synthesis. The light organic phase is washed with water, dried and, if desired, distilled. The washing water is neutralised, stripped in order to free it from dissolved organic components and removed from the system as waste water.

Abstract: A coin sorter 14 in which a sorting head 56 is positioned over a rotating pliable disc 54 and wherein coins are sorted by the combination of an inwardly or outwardly extending tapered edge 76 and a series of pins 114a - 114e generally positioned in an outwardly extending line spaced from the tapered edge 76. The spacing between the line of pins 114a - 114e and tapered edge 76 changes with radial dimension, whereby coins of different diameter are urged over the tapered edge 76 by pins at different positions. The coins are then captured between the head 56 and the pliable disc 54 and rotated to exit positions which are unique for each coin about the outside of the sorting head 56. <IMAGE>

Abstract: To ensure stability for jib cranes, in which in transportation thereof it is important to observe certain axle loadings in order to improve the travel qualities thereof, provided on the upper portion of the crane beside the fixedly arranged counterloads 3 is a movable counterload 4 which is connected to the upper portion of the crane by way of a pivotable counterload arm 5. The movable counterload 4 is rotated about the connecting joint 6 with the counterload arm simultaneously with and in the same sense as the pivotal movement of the counterload arm from the operating position (solid lines) into the travel position or vice-versa. By virtue of the rotary movement of the movable counterload 4 about the connecting joint 6 with the counterload arm 5, they face outwardly at a right angle to the longitudinal axis of the jib crane both in the operating position in the direction of the rails, and also in the travel position. The pivotal movement of the counterload arm and the rotary movement of the movable counterload is produced by a drive means. To provide for uniform distribution of load, a movable counterload is arranged on each side of the upper portion of the crane and is pivoted and rotated synchronously. <IMAGE>
Patent DE-3918265-A1 (DE)
Inventor: WUEST WILLI DR
IPC: C09K23/02
Filed: 1989-06-05
Abstract: In a process for preparing tenside mixtures based on alkyl ether sulphonates or their salts (ether sulphonates) as the main component and which are particularly suitable for use in tertiary crude oil extraction, alkyl ether sulphates are reacted with an aqueous solution of an alkali sulphate at temperatures of 160 to 220 DEG C. To prepare admixtures of the ether sulphonates based on alkoxylated alcohols of natural and/or synthetic origin and which are essentially free from sulphate salts, not more than approximately equal quantities of the alkoxylated alcohols are reacted in aqueous medium of weakly alkaline pH with a stoichiometric excess of alkali sulphate and, if necessary, allowed to further react, preferably under the specified reaction conditions. The resultant tenside mixture is then extracted with at least essentially water-insoluble alcohols at lower, but still high, temperatures. The tenside mixtures obtained can be used, in particular admixed with residual alcohol from the extraction stage, for tertiary crude oil extraction.

Filed: 1989-12-12
Abstract: An improved micro-implantation method and apparatus for filling depressed scars, unsymmetrical orbital floors, and superficial bone defects is provided for use in reconstructive surgery procedures. The method employs textured micro particles having an outside diameter between about 20 and 3000 microns which may be injected with an appropriate physiologic vehicle and hypodermic needle and the syringe into a predetermined locus, such as, for example, into the base of depressed scars, beneath the skin in areas of depression and beneath the perichondrium or periosteum in surface irregularities of bone and cartilage. These textured micro particles have been found to enable the filling of defects in reconstructive surgery and because of their textured surface tissue ingrowth is encouraged, so that dislodgement and migration is prevented. <IMAGE>

Filed: 1990-07-06
Abstract: Mode conversion process for a dual input/output port memory device comprising an access port to a RAM memory and an access port to a SAM memory. The access port to the SAM memory can be the subject of a conversion of a sequential write mode (SW) into a sequential read mode (SR) via a pseudo-read transfer mode (PRT) without transferring data in the case of the comparing of original data with the data extracted from the access port to the SAM memory when testing the SAM memory. It is easy to check whether the access port to the RAM memory and the access port to the SAM memory are normal or abnormal at the juncture of the slice on which the memory device is formed during bulk manufacture of the dual input/output port memory device. <IMAGE>

Title: Inner hole cutting of rod-like workpieces - e.g. semiconductor rods, and removing disks produced and risks arising from final cutting stage
Inventor: MALCOK HANIFI DIPL ING
IPC: B28D5/00
Filed: 1990-08-03
Abstract: In the inner hole cutting of rod-like workpieces, e.g. semiconductor rods, disks are removed form the workpieces in such a way that the cutting edge cuts through the workpiece using a cooling lubricant and a pushing movement is employed between workpieces and rotating cutting sheet. At the end of the cutting process, at or after complete sepn. of the workpiece and before sepn. of cutting band, a vacuum appts. is brought up to the discs. A vacuum of necessary cohesion is produced and the discs removed after complete sepn. Novelty is that the vacuum is monitored and when the presecribed lowest value is not reached, the pushing movement between workpiece and cutting sheet is stopped. An appts. is also claimed. ADVANTAGE - Thin discs can be sepd. from the workpiece and the risks arising in the final cutting stage and on removal of the discs are reduced.

Inventor: THUNS MICHAEL ANDREAS
IPC: G08G1/09
Filed: 1991-03-28
Abstract: The components consist of a receiver and decoder suited to a tranmission and distributor network, where the transmission system uses a tone radio, a control computer, and a vehicle control. The receiver and decoder (1) converts the information coming from the transmitter network through the vehicle aerial into a form usable by the computer (2). The computer evaluates the incoming information, and takes into consideration only such data as is relevant to the vehicle. Instructions and advice to the vehicle driver are given by a display unit. Furthermore, the computer evaluates the actual vehicle data, direction of travel, speed, and vehicle position, and compares it with the incoming guide data. A part (3) controls the vehicle functions directly, having a direct influence on the max. speed of the vehicle so that independently of the driver no exceeding of the speed limit is not possible. USE/ADVANTAGE - To improve safety on roads by controlling speed and distance between vehicles.
