Title: Strip guide-shells for cold rolling mill - where guide shells contain small rollers confined to the central part of the shell
Inventor: BERNET EDUARD
IPC: B21B41/08
Filed: 1974-02-22

Title: Picking up granular stacked material - mixing scraper for feeding main scoop which loads conveyor belt
Inventor: PIONTEK GUENTER
IPC: B65G65/20
Filed: 1974-05-16
Abstract: The machine for granular material transfer has a scoop wheel with buckets. The material in the heap is loosened above this wheel by a loosing mechanism. This arrangement is used to ensure uniform composition of the scooped granular material which has been originally deposited in layers of different consistency. The arrangement also ensures that granular material which tends to cake together is mixed uniformly on picking up. The loader has a rotating scooping wheel 4 with buckets 5. These buckets load granular material on the conveyor belt 7. A motor 8 driven scraper screw loosens material over a long region above the scooping wheel. This scraper screw has a central cylinder 9 and helical rib 13 which is held on the roller by pins so that a clearance exists between these two components. This gap ensures free passage of the material.

Title: Combined engine and electric motor transmission - with motor transmitting torque between engine and differential as brake or clutch
Inventor: HAGEDORN GERHARD DIPL ING
IPC: B60L50/16
Filed: 1974-07-17

Title: Automatic control for windscreen wiper - with wiping resistance monitored measuring motor current to control interval between wipes
Inventor: SCHEURICH HANS-JUERGEN
IPC: B60S1/08
Filed: 1975-02-05
Abstract: The windscreen wipers are fitted with an electronic control which monitors the motor current. As the current drops, i.e. with increasing water coverage of the screen, the motor current is increased to speed the wiping action. The system also monitors the time for each cycle, comprising wiping cycle and interval between wipes. A simple capacitor charging circuit is used for this. The system automatically adjusts the wiping speed, and the time interval between wipes to ensure a clear windscreen, without the driver having to lose any attention from his driving. The system can also be used for headlamp wipers/washers whose action it is difficult to judge from the driving position.
Patent DE-2506241-A1 (DE)
Title: Throwing line for water rescue - with line loosely folded inside soft ballasted bag
Inventor: LINDQVIST LARS-HAAKAN
IPC: B63C9/26
Filed: 1975-02-14
Abstract: The throwing line (1) is folded inside a soft cover (3) whose end is closed off to locate a foam rubber pad (7). This is weighted with a ballast weight (2) cushioned inside the foam, with the foam large enough to enable the system to float. The ballast weight enables the user to throw the line more accurately. The free end of the line is fitted with a clasp (10, 11) to secure it to a ship's rail etc. As the container is thrown a fastener tag (9) at the open end of the container is ripped open and the line is paid out. A hand grip loop at the other end serves to rescue the swimmer.

IPC: A61K6/90
Filed: 1975-03-14
Abstract: Moulding compsns. contain a water soluble alginate, filler, gelling agent, inhibitor, and 0.01-2.5 wt. % potassium diphosphate as control agent. The compsn. is used for dental moulds and has a higher flow and lower gel and set times than other compsns. thus enabling truer moulds to be taken. The moulding material is also cheaper and longer lasting as less alginate is used.
Patent DE-2520345-A1 (DE)
Title: Nuclear fuel rod held in plate by easily released fixing - with axially slit bulbous head which naps into engagement
Inventor: NISSEL BERTFRIED
IPC: G21C3/334
Filed: 1975-05-07
Abstract: A fixing device for nuclear reactor fuel rods consists of a rod holding plate with holes for the end portions of the rods. Each end portion of a rod comprises, longitudinally in succession: an abutment surface (stepped-in shoulder), an annular groove of width greater than the depth of the holding plate, a shoulder (stepped-out shoulder) and an associated bulge or thickening of diameter larger than the hole through the plate; the end portion is also split by axial slits extending from the bottom tip at least as far as the annular groove, and the resultant 'fingers' between the slits are of elastic material. Thus, when the end portion is pushed through the plate, the fingers spring out and engage by the stepped-out shoulder and bulge against the lower face of the plate. Means for bringing the fingers together, to release this snap-fit are provided, esp. a coaxial ring, tube etc. on a releasing plate, which is raised and pushed axially onto the external faces of the fingers, so that mutual tapering of the ring and fingers closes the fingers and permits withdrawal of the fuel rod. The fuel rods can be reliably and easily engaged in the holding plate and easily released from it.
Patent DE-2527986-A1 (DE)
Title: Protection ring for braided corrugated hose - has castellated edges and overlapping ends
Inventor: HOLZHAUSEN WIELAND DR ING DR
IPC: F16L11/12
Filed: 1975-06-24
Abstract: A ring to prevent chafing of the braiding around the crests of corrugations of flexible hose, to prevent cracks and leakage, is made from a strip of suitable material such as steel, copper alloy or plastics. Slots are cut along opposite edges of the strip to form equally spaced tongues (2). The strip is then wrapped around the crest of the corrugation until the ends overlap. The tongues (2) are then bent inwards to grip the underlying opposite end of the strip. An alternative design uses two separate half rings fitted between the fixing ring and the crest of the corrugation.
Patent DE-2532697-A1 (DE)
Title: Electro mechanical vibrator with flexible drive shaft - has rotational frequency of vibration greater than shaft speed
IPC: B06B1/16
Filed: 1975-07-22
Abstract: The electro-mechanical vibrator has a cylindrical housing (1) with an electric motor (2). The motor shaft (2a) is hollow and drives the cylindrical out-of-balance weight (4) through the keys (7) and flexible shaft (3). The shaft (3) is sufficiently flexible that the axis (10) of the out-of-balance weight (4) remains parallel to the motor axis (9), when the shaft deflects due to centrifugal force. Because the balance weight axis (10) remains parallel to the motor axis (9) the balance weight (4) runs squarely on the track (5) without slip. This ensures that the rotational frequency of the vibration due to the out-of-balance force is greater than the rotational speed of the motor (2).
