Title: Concrete treatment to increase weather and chemical resistance - by injecting liquid impregnant, pref. polymerisable monomer esp. MMA into ducts
Inventor: BRETT WILLIAM J
IPC: C04B41/61
Filed: 1978-04-17
Abstract: Concrete elements contg. ducts with externally-accessible opening(s) and liquid-permeable walls are treated by injecting a liquid into these ducts under pressure, so that the liquid penetrates the concrete.

Title: Traversing unit - has a sprung component to absorb and store energy at reversing points
Inventor: JOHNSTON PETER WILLIAM GILBEY
IPC: B65H54/28
Filed: 1978-05-19
Abstract: A traversing unit, such as for the reciprocating motion of a yarn guide on a winding machine, has additional components to support the braking and accelerating actions of the unit. They are fitted to a component so that they exert a constant action at the point of direc tion change. Pref. at each point of direction change there is a pivoted arm with a spring so that energy is absorbed and stored in the spring while it is being pressed. In another form, there is a leaf spring at each direction change opint to absorb and store the energy exerted on it by a body which rotates when the traverse reaches the reversing point. The design reduces wear on the cams and cam tracers used to effect the reciprocating motion.

IPC: B65H67/06
Filed: 1978-12-23
Abstract: The supply holder to deliver individual spools through the base to a drop shaft has a base opening which is at least double the width of the carrying trough (32). The slide (28) next to the carrying trough (32) has mechanical clearing units (33, 34, 35) in constant contact with the lower spool layer in the supply holder (11). The clearing units (33, 34, 35) form a grid running parallel to the longitudinal direction of the carrying trough (32) in the form of round rods (35) and rotating rollers (33, 34). The slide (28) has an intermittent drive (39) with a flexible transmission. The base plate of the holder (11) are angled at 11-15 degrees to the horizontal, to form a funnel leading to a central opening. The spool holder (11) is removable and replaceable on the frame (19) carrying the slide (28) and its side walls form a trapezoid with the widest side forming the upper edge. There are lips (21) below the upper edge, so that holders (11) can be stacked vertically together. The system prevents the spools from jamming, so that stoppages are reduced and the spools are supplied smoothly.

Title: Walking beam furnace for ingots, slabs, billets etc. - using slow heating in low temp. zone to avoid cracks, and fast heating in high temp. zone to avoid oxidn.
Inventor: POHL HANS CHRISTOPH DR ING
IPC: F27B9/20

Abstract: The furnace consists of a low temp. zone (1), and a high temp. zone (2), where zone (1) is on a lower level than zone (2); and the space between adjacent workpieces can be varied during their travel between the two zones. The difference in height of the two zones is achieved by locating the stationary beams in zone (1) on a lower level than the stationary beams in zone (2). The surfaces of the stationary- and/or the moving-beams pref. have profiled shapes. Moderate heating speeds are used below the AC3 point of the steel workpieces in zone (1) to avoid cracks; but higher heating speeds above AC3 are used in zone (2) to minimise scaling of the steel.

Title: Electrolytic capacitor mfr. - by dipping first in release agent and then inversed in fluidised sinter powder bed
Inventor: PETRICK PAUL DR
IPC: H01G9/00
Filed: 1979-05-21
Abstract: Electrolytic capacitors are produced by first dipping them down to below the welded joint between the valve metal wire on the anode and the connecting wire into a release agent. They are then repeatedly preheated and dipped, suspended on the cathode wire, into a fluidised sinter be until the coating has reached the desired thickness. The pref. anti-stick agent is silicone oil, silicone grease or wax or a hydrocarbon basis. The pref. fluidised sinter bed powder is epoxy resin, polyester or polypropylene. The coating is cured at 110-170 degrees C for 15-60 mins, and the anode connecting wire is finally cleaned by powder blasting, pref. using ground kernels of stone fruit or shell. This facilitates the removal of the sinter powder which adheres on a connecting wire.

Title: Universal prefab. staircase banisters string section - has spacers permitting standardisation and storey height adaptation
Inventor: SCHULZ VOLKER
IPC: E04F11/18
Filed: 1979-08-09
Abstract: A harp-shaped unit for balustrades in staircases is made up from prefab components. It is esp. suitable for single-family houses or terraced or multi-family residential buildings. The units are standardised, and assembled with intermediate pieces so that these compensate for dimensional differences in varying storey heights. Those in a base frame may be thinner.
