Patent DE-3836787-A1 (DE)
Title: Implantable hydraulic penis prosthesis
Inventor: THUEROFF JOACHIM PROF DR MED
IPC: A61B17/12
Filed: 1988-10-28
Abstract: An implantable hydraulic penis prosthesis is intended to restore the physiological erectile function without destroying or removing any anatomical structures. The implantable hydraulic penis prosthesis comprises one pair of occlusive cuffs (32, 34) which are placed around the associated crura of the penis (18, 20). The inner surfaces of the occlusive cuffs (32, 34) are provided with inflatable domes (56) which are connected via a control valve (44) with associated tubes (36, 38, 64, 66) with a pump reservoir (42). The reservoir and the entire system are filled with a hydraulic working fluid. The function of the device is based on the principle that hydraulic fluid is transported from the reservoir into the dilatable domes by the control valve on squeezing of the pump reservoir. The dilation of the domes compresses the crura of the penis and hence the deep veins of the penis (24b, 26b). Throttling of the venous blood flow from the cavernous bodies causes filling of the tissue of the cavernous bodies with blood and hence an erection. The device can be deactivated by compressing the control valve, so that bypass channels are formed. The hydraulic fluid can flow through these channels from the domes back into the pump reservoir (Fig. 1). <IMAGE>

Title: Insect-cleaning device for vehicle windows
Inventor: SCHMIDT NORBERT
IPC: B60S1/38
Filed: 1988-11-10
Abstract: The object of the invention is to remove the firmly adhering insect remains from the windscreen, to be precise during the journey by means of a windscreen wiper. A cleaning element of small length is moved to and fro at low speed on a windscreen wiper (wiper arm) in the longitudinal direction thereof, whilst the windscreen wiper carries out its wiping movements. The short element, which can also rotate, effects a higher pressure on the point to be cleaned than a cleaning element the length of the wiper and thus results in a maximum cleaning effect.

Title: Fastening element for connecting thin components
Inventor: GROESCHEL FRIEDRICH DR
IPC: F16B19/10
Filed: 1988-12-24
Abstract: The fastening element for connecting thin components (11, 12) is composed of a sleeve (1) having a rear-side flange (4) and of a pin (2) which passes through the sleeve (1) and has a punching head (5). The sleeve (1) is supported axially, on the inner side, on the portion (A) which tapers in the setting direction and belongs to that region of the pin (2) which adjoins the punching head (5) to the rear, for which purpose the sleeve (1) exhibits a corresponding inner contour (3a). During the setting procedure, the pin (2) and the sleeve (1) pass through the components (11, 12). The flange (4) runs up against the components (11, 12), and the tapering portion (A), together with the corresponding contour (3a), effects an expansion of the sleeve (1) on the rear side of the component (12). <IMAGE>

Title: Washing or rinsing machine with a program control which can be selected from an operating panel
Inventor: BRODZINA LISELOTTE
IPC: A47L15/44
Filed: 1989-02-14
Abstract: The microcomputer of the washing or rinsing machine program control receives a presence signal when the storing and dosing device is connected. Two data sets are stored in the microcomputer for processing, of which the one data set contains control instructions, comprising operating instructions which can be transmitted to an operating panel of the washing or rinsing machine when the storing and dosing device is not connected, and of which the other data set, only available when the presence signal is received, contains control instructions, comprising special operating instructions which can be transmitted to the operating panel of the washing or rinsing machine and to the operating panel of the storing and dosing device. In this way the program sequence of a washing or rinsing machine can be adapted automatically, without changing the so-called hardware of its program control, to the state of connection and/or operational readiness of a dosing and metering device.

Patent DE-3909896-A1 (DE)
Inventor: BLAND PATRICK MAURICE
IPC: G06F13/362
Filed: 1989-03-25
Abstract: A computer system includes a page memory in which a row address accompanied by a row address strobe (RAS) is followed by a column address accompanied by a column address strobe (CAS) to read data from a memory location during a memory cycle. When, in a following memory cycle, a further location from the same page is to be accessed, the row address and the RAS remain constant and a new column address is used with the CAS being precharged by switching it to its OFF state and then returning it to its ON state. This is normally done at the start of the following memory cycle. In the present system, the data is read and latched shortly after arrival of the column address and CAS in the first of the memory cycles so that the CAS recharge can take place at the end of the first memory cycle and before the start of the following memory cycle.

Title: Power drive for injection machine - in which rotating screw and piston movement during injection draw power from same motor and gearbox
Inventor: LAMPL ALFRED DIPL ING DR
IPC: B29C45/77
Filed: 1989-11-07
Abstract: Power for both the rotating screw and linear forward screw movement during an injection moulding process is obtainable from the same motor. Polymer melt fills the space in front of the screw by means of the rotating screw driven by a motor through a gear box. When sufficient polymer is available for a single shot the screw moves forward during injection as hydraulic fluid is pumped into a cylinder behind a piston attached to the screw. Power for the hydraulic pump also comes from the motor driven generator. ADVANTAGE - The equipment has a simple construction and uses less energy. Less individual components are necessary and material costs are reduced.
