Title: Magazine for holding printing plates - delivers them automatically to plate holder using intermediary transporter
Inventor: KAEDING JUERGEN
IPC: B41L47/20
Filed: 1976-11-09
Abstract: Printing machine for paper sheets permits printing plates (12) to be changed automatically during operation without having to stop the machine. In order to achieve this the plates are stored in a magazine (17) from which they can be extracted individually and at predetermined intervals for transfer to the plate holder (16). A transporter (27) conveys the plates from the magazine to the holder. The plates are stacked in the magazine and have their printing surfaces directed towards the magazine outlet (18). The plates are moved to the discharge point by a spring-loaded or pneumatically driven slide (23) within the magazine.

Title: Reduced noise gas throttle valve - has larger outlet than inlet to passageway through rotatable valve body
IPC: F16K5/06
Filed: 1976-12-03
Abstract: The throttle valve for flowing gas reduces the noise of operation and has several valve seats spaced apart from one another with which interact a rotatable valve body (1) having a passageway for the gas. The passageway lies at right angles to the rotational axis (3) of the body. The cross-sectional area of the passageway at the outlet side (5) is greater than that at the outlet (4). Both the inlet and outlet of the valve body interact with separate valve seats (14, 15) with leading edges (19, 20). The valve body is rotatable about its axis (3) in order to vary the active throughflow cross-section at inlet and outlet both simultaneously and in a predetermined ratio to one another.

Title: Low level flat top container platform - has wheels for forward and transverse motion
Inventor: OBRETINOW TODOR DR ING
IPC: B65D19/42
Filed: 1976-12-07

Title: Hammer mill dryer for sludge and faeces - with impact plates near feed at positive angle and near discharge at negative angle to flow direction
Inventor: BEELMANN RICHARD
IPC: B02C13/28
Filed: 1977-01-24
Abstract: A machine for the drying and comminution of sludge and faeces consists of a horizontal shaft with several rows of hammers which is arranged in an axial-flow casing. The impact surfaces of the impact plates at the head of each hammer are inclined near the inlet in the direction of the axial flow, but near the outlet opposite to this direction. The resulting longer residence time greatly improves the drying operation. The better drying prevents the adhesion of sludge on the casing.

Title: Bottle handling unit for cleaning machine - has multitrack conveyor with common discharge platform to reduce operating noise
Inventor: WENGER HEINRICH DR
IPC: B65G47/71
Filed: 1977-03-04
Abstract: The bottle handling unit for a cleaning machine has a multi-track conveyer (4) with staggered individual conveyer tracks (12-17) running in the discharge direction (26). At the beginning of each track is positioned short individual conveyers (5) operating at right angles to the multi-track system.

Title: Bathroom type door lock operated from inside - has two=part tongue swung over to release coupling pieces from nut (OE 15.10.78)
Inventor: ORLIK JOSEF
IPC: E05B55/04
Filed: 1978-12-08
Abstract: There is a latch, withdrawable by a lock nut, in the door lock, for putting the door knob, or similar, out of action from the inside, esp. as fitted on toilet or bathroom doors. The lock tongue accommodating the knob is divided into inside and outside parts. The nut is operable by a two-part carrier, with both parts fixed to a tongue part and to each other, and coupled to the nut for swivelling open. Swivelling the inside tongue piece against the opening direction releases the coupling between carrier pieces and their coupling with the nut. This enables the outside door knob to be disengaged without using an additional handle, and can be readily opened from inside even by a small child.
