Title: Device eliminating deflection in die pressure frames - having smaller compensating rams operating centrally in the reverse direction
Inventor: SHIOKAWA SEIJI
IPC: B29C53/04
Filed: 1975-09-15
Abstract: A press device has a pair of parallel support frames at a fixed distance from each other. A fixed framework is attached to the lower one and has a lower die tool on top. Two main hydraulic cylinders are fixed to the top of the main two frames. A movable frame is held above by the rams of the cylinders and has an upper die tool attached. A space near to and along the bottom of the movable frame contains a row of compensating cylinders, and the paths of the main hydraulic cylinder liquid can be connected to those of the smaller compensating cylinders. The system compensates for deflection of the fixed and moving frames when under pressure e.g. when moulding/shaping long narrow components; it thus eliminates concavity/convexity in the pressed articles.

Patent DE-2545303-A1 (DE)
Title: Brushless AC generator with stationary windings - has optimised excitation circuit flux path and low iron content in carrier ring
Inventor: KUCERA JOSEF DIPL ING
IPC: H02K19/24
Filed: 1975-10-09
Abstract: In claw pole a.c. generators an iron structure rotates between the stationary field winding and the stationary, usually outer, armature. In such machines, due to their cylindrical contruction, the flux loading tends to be uneven being lower at the larger diameter. Such machines are therefore not as well utilised as they might be. By making the excitation winding carrier (18) of a shape that gives constant flux loading in its radial direction the optimum conditions are approached. The space saved by the resultant reduction in iron in the carrier ring (18) may be given over to a larger field winding (21) which will increase the efficiency of the machine, or the dimensions may be reduced by a corresponding amount to give a smaller machine.

Title: Power supply for arc welding with alternating current - where direct current is used to strike the arc and automatically switched off
Inventor: ROEHM ERNST DIPL ING
IPC: B23K9/067
Filed: 1976-05-18
Abstract: In arc welding, esp. in hazardous conditions, e.g. in a confined space, the power supply uses a transformer with a sec. circuit into which a rectifier stack can be switched. Under no-load conditions, the rectifier is connected in the sec. circuit, but is automatically cut out at the start of welding without interrupting the a.c. welding current. The rectifier can pref. be bridged over by a by-pass circuit contg. a controlled switch, esp. a thyristor. Used esp. for welding inside boilers, where the max. permissible effective a.c. voltage under no load is 42 V, but it is sometimes difficult to strike the arc, e.g. when using TIG welding with low currents. The max. permissible d.c. voltage is 100 V, and the invention exploits this fact for striking the arc.

Title: Blockage clearing oxygen lance - for coke oven batteries with specified sections and operated with specified oxygen pressures
Inventor: THIERSCH FRIEDRICH DR
IPC: C10B43/10
Filed: 1976-08-03
Abstract: Passages, nozzle and channels in heated refractory masonry of industrial plant such as coke oven batteries are burned out and cleared by oxygen lances. On the way to the blockage in a heating flue an oxygen pressure of 1-6 atm. is maintained on the fired lance. On arrival this is raised to 6-26 atm. (11-16 atm.) and the heating flue is maintained at a negative pressure of 1-25mm w.g. The pref. oxygen lance for this application consists of an outer steel pipe in which wire cores of steel have been inserted. The oxygen flows at the specified pressure through the annulus between wires and pipe. The pref. ratios of the cross-sectional areas of the lance pipe material thickness Q1 to that of the core wires Q2 and to that of the annulus available for the oxygen flow is Q1:Q2:Q3 = 1.2:1.0:0.7. This prevents the extinction of the flame on the way and on the site. The lance material cannot melt together with the refractory material.

Title: Secondary feed box for laminating fibre board - applies high density mineral slurry without turbulence to formed layer
Inventor: MCINTYRE HOWARD LEE
IPC: D21F1/02
Filed: 1976-08-10
Abstract: A secondary feed box for the manipulation of slurries with a high concentration of solid matter, is arranged transversely above a Fourdrinier machine for the production of flat materials. It has a piping manifold for distributing the slurry into a first chamber with a flow guide plate beneath which the slurry passes originally. In the first chamber there is also a perforated cylinder into and through which the slurry flows, being thoroughly mixed and distributed uniformly across the width of the chamber. The slurry overflows from the first into a second chamber which also has a flow guide plate. The bottom edge of this plate is designed correspondingly to the hydraulic flow, so that as the slurry flows under it any turbulence is damped down and the flow is guided through to a second overflow. The overflow follows a ramp a short distance from which there is a plate forming with the front edge of the plate, a feed slot. The edge of the front plate is positioned from 0 to 75 mm below the edge of the ramp and the slurry is directed downwards on to the base material carried by a permeable belt. The surfaces of the first and second overflows are parallel to the carrier belt and the form of the inner lower walls of the first and second chambers corresponds to the hydraulic form of the flowing slurry. The guide plate in the second chamber and the feed plate for the ramp are adjustable horizontally and vertically. The secondary feed box is partic. applicable to the handling of high density slurry for mfg. mineral fibre boards, and esp. to the application on a low density mineral backing of a dense surface layer.
