Patent DE-2520494-A1 (DE)
Title: Radar display with radial intensity variation - using separate deflector and intensity modulation circuits
Inventor: SENGER HANS-JUERGEN
IPC: G01S7/12
Filed: 1975-05-07
Abstract: A plan position indicator contains a CRT, a deflector system, a deflector timing circuit generating deflection signals, an intensity modulation circuit for the tube and a video amplifier producing, from the input video signal, a picture signal for the tube having an amplitude lying within a defined envelope. During the sweep time the envelope amplitude of the signal, which is formed from the modulation and picture signals and influences the ray intensity, increases with time so that the brightness of the targets and concentric circles diminishes towards the screen's edge. Alternatively, the envelope amplitude may vary linearly with time or may be constant, in which case the intensity modulation amplitude increases.

Title: Pulse radar station for land motor vehicles - determines instantaneous distance and relative speed of obstacle in front of it
Inventor: WIESBECK WERNER DR ING
IPC: G01S13/92
Filed: 1975-05-28
Abstract: A pulse radar station for land motor vehicles. The radar transmitter generates pulses of a duration equal to twice the signal propagation the station and the limit of a specified range. A controlled attenuator is provided between the transmitter and antenna, with a maximum attenuation of between 20 and 100 dB, and is set after a certain delay from the beginning of each radar pulse from its minimum to maximum attenuation. This delay corresponds to the required distance resolution; and received signals and a part of a transmitted pulse are applied to a mixer to which an evaluation device for range and speed determination is connected.

Inventor: JONES SAMUEL H
IPC: C21D8/06
Filed: 1975-07-08
Abstract: Stress relieved, pre-strengthened elongated steel workpieces are made by cold working a carbon or low alloy steel workpiece, straightening it by reverse bending and rapidly heating to between 500 degrees F and critical temp. of the steel in 10 minutes.

Patent DE-2544016-A1 (DE)
Title: Continuous casting metal slabs - where solidified webs in slab avoid bulging and reduce number of support rolls required
IPC: B22D11/04
Filed: 1975-10-02
Abstract: Bulging out is prevented or reduced when the slabs or billets leave a chilled mould and consist of a solidified outer wall surrounding a core of molten metal. Solid webs are created between the opposed solidified walls of the billet and counteract the ferrostatic pressure so that the conventional support rolls can be completely or partly eliminated. The webs are pref. obtd. by feeding a cold plate continuously through the mould so the melt solifidies on the plate to form a web; alternatively, a water-cooled box may be suspended in the mould so a solidified web forms in the cast billet.
Patent DE-2550328-A1 (DE)
Title: Yarn delivery drum store - has an additional angled freely-rotating drum to give constant yarn tension
Inventor: PAEPKE HORST
IPC: B65H51/22
Filed: 1975-11-08
Abstract: Appts. is claimed for the delivery of yarn to a textile machine such as a circular knitter, where the yarn is coiled as a store round a belt-driven drum, where the drum mantle is composed of rods. The driven drum has a freely-rotating drum mounted alongside, with its rotary axis slightly angled to the axis of the driven drum. The windings of the yarn stores are passed round both drums. The design gives a simplified yarn store and delivery system, the angular pitch of the freely-rotating drum increasing the length of the yarn coils from the entry to the exit points so that the yarn has a constant tension applied to it.

Title: Solar heat storage installation using heating oil tanks - enveloped in insulation layers and packed in sand mass
IPC: F28D20/00
Filed: 1975-11-26
Abstract: The installation consists of a number of mutually isolated warm water containers, the majority of which are similar and consist of battery tanks, and/or a number of tanks for warm water which are spaced away from each other and are partly embedded in granular material such as sand Heating oil battery tanks may be used for the fluid containers on account of their ability to withstand temperature changes, and where these are of polyethylene or polypropylene, they are given side reinforcement. The battery of tanks insulated against each other is packed closely, and has an overall enclosure with better insulating qualities than those of the individual wrappings. Thermodynamic advantages of avoiding the mixing of masses of fluid in the storage vessels, at different temperatures, are achieved by exploiting the dimensions of the buildings, esp. as regards cellars and beneath cellar floors. Instea dof a large container with temperature layers, a series of small, easily and cheaply obtained vessels is used. Sand for embedding the vessels is cheap and has about one third of the heat capacity of water.

Title: Welding arc striking pulse - produced by glow tube discharging capacitor through pulse transformer on reaching breakdown voltage
Inventor: JUNG WERNER
IPC: B23K9/073
Filed: 1976-04-02
Abstract: A circuit to strike an arc in a d.c. arc welding system produced arc-striking pulses using a capacitor which has the prim. winding of a pulse transformer (with the sec. winding in the welding current circuit) in series with a switching element in its discharge circuit. The switching element is a glow-discharge tube which initiates the capacitor discharge when its breakdown voltage is reached. This replaces the thyristor, requiring complex firing units, by a simple uncontrolled electronic tube, reducing the cost considerably. The system is also suitable for the striking and/or stabilisation of an arc for a.c. welding systems.
Patent DE-2615217-A1 (DE)
Title: Push button switch with guide plate - has actuating cam between contact springs and push button pin hinged to guide plate
Inventor: BAUER HANS JUERGEN
IPC: H01H13/12
Filed: 1976-04-08
Abstract: The push-button of the switch has a movably held pin (2) in a guide plate (4), in order to actuate contact springs (5) mounted on edge. Between the pin and the contact springs is inserted an actuating cam whose action onto the contact springs is effected by the pins. The actuating cam is formed in one piece with the guide plate, to which it is connected by a film hinge. Alternately the connection may be provided by a leaf spring forming strip. The design has the advantage of avoiding direct contact between the pin and the contact springs, thus reducing negative effects of the switch drive on these springs.
