Patent DE-2349347-A1 (DE)
Title: Brick stack packing system - inserts sheet strip under strap to cover stack sides partially
Inventor: MORGANTE JUN WILHELM
IPC: B65B27/02
Filed: 1973-10-02
Abstract: A strip of sheet material is inserted on one or two sides of the stack, preferably the top, between the stack itself and the binding strap, so as partly to cover the stack sides. The sheet can be unwound from a roll, a perforation mechanism being provided between the roll and the packing station. This mechanism can be arranged to operate so that the line of perforations is always between two stacks. Separation is effected by pulling the stacks apart. The strap may be of steel or plastics sheet.

Title: Radio detection set for finding buried persons - radiates two fixed frequencies and involves summation unit on person
Inventor: SCHIEFER GERD DR-ING
IPC: G01S13/75
Filed: 1973-10-20
Abstract: The apparatus operates in the frequency range 104 to 3 x 109 Hz. The responder on an object or person, consists of an aerial, capacitors, an inductance and a nonlinear component, e.g. a germanium diode, which generates the sum frequency and re-radiates it back to the search unit. The responder is in the form of a thin foil or plate with aerial conductors at its edges forming a frame aerial with a gap bridged by the above components; the spacing between the two radiated frequencies is smaller than 1% of the highest frequency; the responder size corresponds to that of an identity card, and is worn in the card or one side of it.

Title: Paper laminate bonded by stamping - uses pair of bevelled wheels to produce double compression forces
Inventor: NYSTRAND ERNST DANIEL
IPC: B32B7/14
Filed: 1974-01-31
Abstract: Laminate has two or more elongate layers bonded without adhesive by a pair of longitudinally extending perforated lines. The stamping pressure is approx. 2812-5625 kg/cm2.

Title: Car wash with washing liquid jets - system of nozzles assembled in a portico
Inventor: KROLL JENS M DR
IPC: B60S3/06
Filed: 1974-02-14
Abstract: In the present way of automatically washing a car the water spraying and brush passage is done simultaneously therefore the solution has no time to act. Since an independent car portico relative movement for this purpose is time consuming, the water sprinkling is done immediately before the washing operation starts, with the portico in fixed position. Some preferred ways of doing this and reaching all parts of the car include spraying with fixed nozzles and decreasing pressure, with tilting nozzles or with nozzles fixed to the end of an arm movable along the vehicle.

Title: Flexible seal for communications cables - has variable-diameter elastic pocket which is inflated inwards by injecting filler externally
Inventor: SCHILLING WERNER DIPL ING
IPC: B29C48/12
Filed: 1974-08-26
Abstract: The flexible seal, for communication cables, consists of an elastic 'pocket' with a circular and a U-shaped longitudinal cross-section. (The lip is clamped between cover plate and body). The sides (21) of the seal are thicker than the rest and reinforced. The end of the seal is thin-walled and has holes (24). Filling material (32) is injected into the pocket from the outside so that it expands inwards and forms a tight seal. The advantage of the seal lies in its variable dismeter and in its sealing pressure being altered simply by altering the injecting pressure of the filler.

Title: Sectional bridge structure on columns - is built at correct level by using forward projecting temporary support
Inventor: HILLBRAND HERFRIED DIPL ING
IPC: E01D21/10
Filed: 1974-11-26
Abstract: The bridge is built on support columns directly at the correct level. The bridge is constructed between the given columns by means of a lever type auxiliary support which rests on the forward column, at the end of the bridge section and a hydraulic actuator which rests on the bridge section is connected to the auxiliary frame by a rope. This hydraulic system lifts bridge sections into position until the next column is reached. The auxiliary support frame rests by one end on the column while the last bridge section is lifted into position by the crane. The auxiliary frame is disconnected after the last bridge section is positioned and the frame is used in building the next bridge span. This method eliminates the of bridge aligning scaffolding.

Title: Hard/soft caramel paste - for sweets processed by admitting compressed air between worm conveyor and mixer tool
Inventor: GOTSCH GUENTER
IPC: B01F7/00
Filed: 1975-03-21
Abstract: Hard and soft caramel pastes, used for the mfre. of sweets, are processed by mixing compressed air to the viscous or plastic paste as it passes through a mixer. The viscosity of the paste is so controlled by its temperature that the air bubbles are retained in the paste. This sasves the laborious and risky manual operation of wrapping the hot viscous paste over hooks. The resulting product now has a fully automatically obtained controlled consistency. The processing takes place in totally enclosed containers under the best hygienic conditions.

Title: Composite, hollow, extruder screw comprises several sections screwed t - to facilitate installation of central cooling tube, and improve cooling of the inner wall
Inventor: BOEKHOFF UWE
IPC: B29C48/58
Filed: 1975-03-25
Abstract: A composite extruder screw is hollow and is characterised in that each pair of screw body components have adjacent ends designed as hubs or shafts of a torsion-resistant hub-shaft connection. The screw body provided with the hub and engages the screw body provided with a shaft end by a hollow threaded nut fitted inside the screw.
