Title: Adjustable multi-section waveguide filter of square cross-section - uses direction of indentations in prefabricated side plates for coarse frequency adjustment
Inventor: MAGNUS JUERGEN DIPL-ING
IPC: H01P1/208
Filed: 1973-08-10
Abstract: The microwave filter consists of one or more waveguide filter sections of rectangular cross-section constructed of interlocking prefabricated metal plates forming the sidewalls, endface cups and partitions which are finally soldered together. At least one of the sidewalls has a bowl shaped indentation which can be directed into the interior of the waveguide or which can be going outward depending on the frequency range of the filter. All sidewalls have identical indentations but can have different cut-outs and attachments. Each partition wall having a coupling hole can with its lugs mate with the appropriate slots in the appropriate slots in the sidewall plates. The so formed individual cavity resonators can be fine adjusted by means of a dielectric plungers fixed to a metal screw in the sidewall. An additional coupling hole in the partition close to the sidewall can be used to alter the coupling by means of a screw. The frequency range is coarse-adjusted by the choice of the number of inward and outward directed indentations.

Title: Hinged opening roof light - has two stay arms which when folded act as locking elements
IPC: E04D13/035
Filed: 1973-09-27
Abstract: Prior design envisage normally the pivoting arrangement approximately half way of the sides of the roof light and the pivots on the leaf are somewhat staggered. As a consequence of this arrangement, the leaf never seals properly and tends to rattle in strong winds. On the present design the two stay arms are situated at the frame end opposite to the hinges. The stay arms have pivots on opposite parts of the leaf, the pivoting points are in different heights in relation to the leaf surface, so that they fold in opposite directions under each other and are for proper sealing individually rested on conveniently placed brackets fitted to the frame.

Title: Hot rolling thick plate on a reversing mill - producing tapered longitudinal sections during intermediate passes
Inventor: STICH WILHELM DIPL ING DR TECH
IPC: B21B1/34
Filed: 1974-01-04
Abstract: Thick plate is hot rolled on a reversing mill with the roll gap continuously increased during the passage of the plate through the mill. A prescribed speed is used for both the rolls and the gap-adjustment, so there is a uniform and progressive increase in thickness from the front end of the plate to the back end after each pass, forming a "reverse thickness counter cone" for balancing the roll pressure while still obtaining the required redn. in thickness. The process is pref. carried out on a reversing mill fitted with pressure devices on the back-up rolls, i.e. for obtaining a uniform thickness right across the plate and a computer is pref. used to obtain "cones" or tapered sections in both the longitudinal and transverse directions. Flat plate with close dimensional tolerance across its entire width is obtd. with compensation for the difference in plate temp. between the front and back ends.

Title: Clip for joining abutting extruded sections - is used where sections each have inwardly inclined flanges into which elongated clip slides
Inventor: DICK GUENTER
IPC: F16B7/04
Filed: 1974-02-21
Abstract: Two extruded sections forming a rail are butted together and joined by an elongated connecting clip which is slid into each section between two inwardly inclined flanges projecting from each section. The flanges have angled internal faces which cooperate with similar inclined faces on the clip which is of very flat 'U' section so that when set screws, threaded into the clip, are screwed down the inclined faces align the two sections and retain them by friction. The clip is useful for joining handrails and balustrades. The rails have outer curved edges facing the same way as the flanges which grip the clips. The setscrews inserted in holes in the clips press against the web of the rail to lock the clips firmly in position.

Title: Control system for piston pump delivering concrete - is separated from pump cylinder and piston for reducing wear
Inventor: BILLE HEINZ
IPC: F04B9/117
Filed: 1974-03-09
Abstract: The sequence control system is used for actuating a piston pump for delivering concrete. The drive cylinder piston is operated by a pressurised media operated changeover valve. The inlet and outlet of the pump is operated by another changeover valve and actuating cylinder for the sliding valve. This system is not subject to excessive wear because the control mechanism is separated from the cylinder cover and piston rod region. However valves are actuated in conjunction with the displacement of the driving cylinder piston. The pump cylinder has nonreturn valves for admitting pressurised medium into the pump cylinder. The driving cylinder and actuating cylinder are connected by valves to the changeover valves via differential pressure connectors.

Title: Press tool for deep drawing double sink units - holds blank with hydraulic pressure during drawing by single action press
Inventor: ADAM KLAUS
IPC: B21D22/26
Filed: 1974-04-23
Abstract: The main patent is for a press tool to produce a double sink unit from sheet metal. This addition to the patent overcomes the need to use a double acting press. The pressure plate supports the die for forming the sink bodies which house the pressure pistons attached to the drawing apparatus. The sheet metal blank is placed in position and the downward motion of the press tool first grips the blank between the plates. Further downward motion forces the punches to form the sink unit whilst the edges of the blank are held by hydraulic pressure in the cylinder which is controlled by a valve.

Title: Accounting machine with two individual paper feeds - has chains driven by respective parallel shafts
Inventor: WUERSCHER HORST ING GRAD
IPC: B41J11/30
Filed: 1974-07-22
Abstract: In an accounting machine two webs or sheets of paper can be fed side by side across a table by two pairs of endless chains supported on sprockets arranged on two parallel shafts. The drive sprockets of the one pair are drivingly connected to one of the shafts. The drive sprockets of the other pair are supported for free rotation on said one shaft but are connected to be driven by the other shaft. The arrangement ensures that the paper-engaging runs of both pairs are in tension when feeding the paper, and that nevertheless the tow pairs can be driven individually.
