Patent DE-2356788-A1 (DE)
Title: Build-up of pneumatic tyres in superposed layers around a drum - the laid-up ply lengths abutting at their ends with a temporary cross-strip bridging the gaps
Inventor: BUSCHMANN ERICH
IPC: B29D30/20
Filed: 1973-11-14
Abstract: The layers (or plies) to be used in the build-up of a pneumatic tyre about a build-up drum have a length corresponding to the circumference of the drum, when laid-up, have their respective ends abutting against one another. At the lines of abutment, esp. at the abutment of that layer nearest the drum, a bridging strip is arranged which is removed before the blank is press-moulded in the vulcanisation press. Critical accuracy in providing the build-up lengths is not required yet there is no risk of imbalance of the finished tyre due to uneven overlap of the layer ends. Tyres made by this process are of improved strength.

Title: Rotary switch with double contact bridge - permits axial motion of bridge by helical compression spring in rotor
Inventor: MEYER HANS PETER
IPC: H01H19/58
Filed: 1973-11-26
Abstract: The double contact bridge is intended for a rotor of a rotary switch for double-side switching. Under the effect of a helical compression spring in the rotor the contact bridge permits an axial motion. It consists of two individual bridges, in which the helical spring is used simultaneously as a holder element for both bridges, in order to form an enclosed component. The individual contact bridges consists of identical flat stampings with guides for the helical spring. They are mounted with their flat sides face to face and form a common aperture for reception of the helical spring. PReferably the bridges are O-shaped and each has a protrusion penetrating the aperture, which forms the helical spring guide.

Title: Drinks dispenser with hot and cold water containers - heats up only certain amount of water at a time
Inventor: GOY HANNS
IPC: A47J31/54
Filed: 1974-01-09
Abstract: The hot drinks dispenser comprises two containers, namely a heating containers which is heated by a heating coil or the like and a water storage container which is mounted above and connected to the heating container by a floating valve and a pressure-reducing valve. The size of the heating container is adapted to the amount of hot water required for a certain time, for example that which is expected to be used within an hour so that sufficient hot water is always available. The floating valve linking the two containers ensures that after removing hot water a corresponding amount of cold water flows out from the storage container above. The pressure release valve prevents the build-up of too much excess pressure in the heating container by allowing the hot water or steam to flow back from the heating container to the storage container.

Title: Signal transmission system - transmits digital and clock pulse coupled analogue and digital information signals
Inventor: MAYER NORBERT DR ING
IPC: H04B14/02
Filed: 1974-04-30
Abstract: A carrier frequency modulated with the signal to be transmitted is combined with a clock pulse train, so that the f.m. output signal of the coupling device contains only pulses which coincide with clock pulses, or are shifted by a fixed amount with respect to these pulses. The f.m. signal is applied to the signal input of a storing flip-flop, and the clock pulse train is applied to its clock pulse input. A needle pulse train is derived from the clock pulse trains, and is passed through a gate controlled by signals derived from the f.m. carrier.

Title: Agricultural bale stacking machine - has support lifting bales into rows and tying mechanism for predetermined numbers
Inventor: JONES RICHARD WILLIAM
IPC: A01D90/08
Filed: 1974-05-14
Abstract: The machine assembles a large number of bales into a stack of predetermined size, and incorporates a support receiving the individual bales in succession from the baler. This lifts the bale to a position where a holding mechanism retains it, and if necessary others above it, until the support lifts another one beneath it. When a vertical row in the prescribed numbers has been formed, it slides or is thrust over a surface to the side. A mechanism is provided to bind the bales in a row together by wire or string etc., and also to tie a predetermined number of rows together. The support can be raised by a hydraulic ram, also used to discharge the bale rows along the side surface.

Title: Mfr of sintered magnesia - using magnesite treated with aq soln of a calcium salt before calcining
Inventor: FOROGLOU ZAPHIRIOS DIPL CHEM
IPC: C04B35/043
Filed: 1974-07-02
Abstract: Sintered magnesia is mfd. from magnesite or similar raw material by calcining at the sintering temp. Prior to calcining, the raw material is treated with an aq. soln. of a water-sol. calcium salt which forms CaO during calcining. The pref. raw material is thermally pre-treated magnesite esp. partly or completely calcined caustic magnesite, whereas the aq. soln. contains pref. calcium nitrate or calcium acetate applied by spray or drips so that the CaO content in the final prod. is min. 0.5% higher than its initial value and/or the ratio CaO:SiO2 is at least 2:1. The process is used for example, in the mfr. of basic refractories. It avoids the formation of cpds. with a low m. pt. in the calcined magnesia.

Title: Irrigation rubber tubing or pipes - have water outlets in wavy tubing which automatically close when pressure falls
Inventor: KABAI DEZSOE
IPC: A01G25/02
Filed: 1974-11-26
Abstract: A length of rubber tubing is produced in a wave form with a central semi-circle joined at each end to two other semi-circles curving in the opposite direction. The centre semi-circle is elastically deformed to a straight line and a hole made in the wall of the tubing. This length of tubing is joined to another length to form a complete loop and when supplied with water at pressure the hole becomes V-shaped and allows the water to pass out freely. When the water pressure falls to zero the hole closes up and prevents the unintended loss of water or the ingress of roots or other foreign matter.

Title: Steam storage installation with super heat storage - uses water from latter to super heat stored stream and returns it to main storage vessel
Inventor: BECKMANN GEORG DIPL ING DR
IPC: F01K3/14
Filed: 1974-12-12
Abstract: The arrangement is particularly intended for providing peak hour energy and is of the type wherein the steam produced in the main storage vessel (3) is superheated by heat provided by the superheat storage vessel (1). The superheat storage vessel drives the hot water collecting at its lower end via the superheater (2), where it superheats steam from the main storage vessel, and from there into the main storage vessel. The water may be fed into the main storage vessel via its normal feed water system. The water emerging from the superheater may be fed to an expansion steam generator (M) before being fed into the main vessel, the steam so produced being fed to an injector in the steam discharge line of the main vessel upstream of the superheater.
