Patent DE-2361823-A1 (DE)
Title: Read and stabilizing amplifier operation - uses two fed-back inverters consisting of switching and load transistors
Inventor: ESSL DIETBERT DIPL PHYS
IPC: H03K3/356
Filed: 1973-12-12
Abstract: The read and stabilizing amplifier is designed according to a clocked flip-flop. The read signals from the transistor storage elements are passed to the control input of the switching transistors. The transistors inserted in the feedback path open the feedback paths before a read signal has been received and the operating point is set in the flip-flop paths. After a read signal has been received, the transistors in the feedback paths are again conductively controlled. The load transistors and the switching transistors are conductively controlled during the period when a read signal is applied to one of the inverters.

Title: Corrugated tube expansion rig - with split die and polyurethane disc compressed between opposing hydraulic rams
Inventor: HANERT ECKEHARD DR ING
IPC: B21D15/06
Filed: 1974-02-15
Abstract: Metal tubes with transverse corrugations for use as expansion pipes in motor cars are produced from smooth tubes by locating the tube between the two halves of a die. The top of one ram carries a disc, made of polyurethane elastomer, with a height (undeformed) a little more than one corrugation pitch. Another ram is introduced from the other end and deforms the disc so that the tube is expanded to a corrugation to suit the cavity in the die. The process is repeated for each corrugation. This is a simple way of producing corrugated tubes with a minimum of costs. The transverse corrugations are quite uniform and the material is subjected neither to undue stretching nor to wall thickness reduction or major cold-working.
Patent DE-2408315-A1 (DE)
Title: Pleat-forming curtain tape for pinched pleats - has floating arrangement of draw strings requiring no special hooks or reinforcement bars
Inventor: ADOLPHS FRIEDHELM
IPC: A47H13/16
Filed: 1974-02-21
Abstract: The pleat-forming curtain tape comprises two parallel draw strings wherein the upper draw cord or string runs within the tape section to be pleated on the reverse side of the tape so as to be longitudinally displaceable in a woven tunnel and inbetween floats over the tape corresponding to the number of individual pleats. The lower draw cord passes alternately from the front to the back of the tape so that where the upper draw cord floats the lower cord floats on the back of the tape and where the upper cord runs in the woven tunnel the lower and cord floats over the front of the tape. If the cords are then pulled so that the parts of the tape within the floating cord section are drawn towards each other then the parts of the tape in the area of the lower cord are brought up close to each other whilst the parts of the tape where the upper cord is in the woven loop are blocked so that the fan-shaped pleats are formed.

The displayed elements are four-digit elements. The digital clock is connected with the on-switch of the receiver and during channel selection is blanked out through an electronic separating filter and a logic circuit. The control voltage switched through by the channel selector operating device is applied through the separating filter to one of the display elements.

The lanes for adjacent container groups are next to each other. Thus a lorry entering one lane to load or discharge can bypass one there already doing so by driving over into the next lane round the crane and then back again. The crane can be of the portal type, running on rails or rubber-tyred wheels. A common rail can be used in the centre, to support the legs of two adjacent cranes.

Title: Direct injection steam heater for continuously flowing liquid - has steam pipe entry and injection pipe arranged vertically
Inventor: GFROERER HANSPETER
IPC: F28C3/06
Filed: 1974-03-25
Abstract: The heater has a cylindrical tubular chamber placed vertically with upper and lower flanges for connection to the pipework carrying the fluid to be heated. A second chamber surrounds the first chamber coaxially and terminates at its upper end in a connection for the heating steam. The second chamber is closed at its lower end. The inner chamber has a series of openings through which steam enters from the outer chamber and mixes with the liquid to be heated. The vertical arrangement of the heater increases the turndown ratio. When steam flow is reduced pressure falls and the liquid being heated flows into the outer chamber blocking some of the openings and compensating the flow.

Patent DE-2430471-A1 (DE)
Title: Telescopic damper for pantograph - with gas cushion to provide rapid raising towards wire
Inventor: BUCHBERGER WILHELM
IPC: B60L5/22
Filed: 1974-06-25
Abstract: The pantograph is fitted with a hydraulic damper to smooth out the pantograph vibrations on the wire and to extend the pantograph onto the wire with a set pressure. In order to speed up the time delay in reapplying the pantograph onto the wire after it has been depressed, such as when travelling under bridges, a pressurised gas pocket is included in the damper. This is separated from the fluid by a floating piston. The damper has assymetric cushioning characteristics and reduces the arcing between the wire and the pantograph. As an alternative to a floating piston, a flexible membrane can separate the fluid and the gas pocket.

Title: Particles septd. from gas flowing in duct - by twisting gas flow and peripheral collection of particles
Inventor: GLASS REINHARD ING GRAD
IPC: B01D45/06
Filed: 1975-03-29
Abstract: A method for separating solid and liquid particles from a flowing gas, without increasing the cross-section of the duct or chimney, consists of deflecting the gas from the its axial flow into a centrifugally and circumferentially accelerated flow, in a flow-twisting zone, and of removing the particles from the periphery of the gas flow, in an annular zone which commences at the commencement of the flow-twisting zone and continues at least to the end of it. In a variant of the method, the flow cross-section is decreased downstream of the flow-twisting zone and particle-removal zone extends over the whole of this region. The particles are removed from the gas, without the need to increase the cross-section. Nevertheless, they are not re-entrained by the high speed of the gas.
