Title: Pusher furnace for heat treating workpieces - has overhead runway shielded from direct heat and continuous through all sections
Inventor: PFENDER KARL
IPC: F27B9/24
Filed: 1973-09-18
Abstract: A pusher type furnace, esp. for heat treatment of workpieces, rods, tubes, wires sheets, under vacuum and/or protective atmosphere, comprises a number of furnace sections successively following one another with gates or locks between them. The roof of each furnace section is fitted with an overhead runway, from which suspended trolleys operate to carry the trolleys and runway is flanked on each side by heaters, esp. vertically suspended gas jet tubes. Equipment is provided for bridging the gap between one length of furnace and the next via the intervening door or lock. Pref. the furnace lining in the roof is sufficiently thick to encase partly or completely the overhead runway and trolley thus protecting it from the heat. Since the overhead runway and trolley and other equipment are shielded from the direct heat action in the furnace, they can operate at higher stresses than would otherwise be possible thus resulting in a considerable saving both in the quantity and quality of materials required.

Title: Control system combining output of two pumps - combined output distributed to all users
Inventor: KRUSCHE ALFRED
IPC: F04B49/08
Filed: 1974-08-22
Abstract: Two pumps on a dredger each perform three functions and the system permits each pump to help the other, when possible. Previous systems have evolved using two extra control valves, one for each pump, and each serving only one of the users of the other pump. Instead, the present system allows all users to be assisted. Moreover, it uses only one extra valve which is an integral part of the control system of one pump. The output of the second pump is connected to it. When the extra valve switches to its alternative condition, it connects a lead from the output of the first pump to the circulation the second pump feeds.

Patent DE-2453634-A1 (DE)
Title: Machine for vibration-compaction of concrete castings - applies forced vibration from below and sympathetic vibration from above
IPC: B30B11/02
Filed: 1974-11-12
Abstract: Concrete castings are made, several at a time, in a partitioned mould. Closely-fitting bottom plates (28) are made to oscillate vertically by the vibrator (30) between the partitions while the moulds are being filled; the oscillations continue and are echoed sympathetically (and ideally in antiphase) by the top plates when these are lowered on to the full moulds. The concrete is compacted between the two sets of plates. The amplitude of the resonant vibration is limited. A stop valve (19) and a closed chamber (20) in a hydraulic system (14, 16, 17) act to limit the oscillations and to define the (positive) minimum momentary pressure the oscillating top plates can exert. Also the mould partitions, which are retractable to release the finished castings, can join in the vibration to some extent.
