Title: Slag removal device - skims slag from surface of molten metal in a furnace
Inventor: SAPKO A I
IPC: F27D3/15
Filed: 1975-06-04
Abstract: Slag removal device includes a slag-collecting vessel filled with coolant and a frame made up of two parts articulated together with one part introduced into the furnace and the other submerged in the vessel. An endless chain encompassing links and rollers is secured on the frame. Plate-like parts brought into contact with the slag are turned with their end faces to one another and disposed in succession on the external side of the links. Knives mounted on the other frame part face each other with their blades, and are spaced at a distance approximating the thickness of the plate-like parts that pass between. The slag is frozen solid on the plate like parts and removed as the plates pass through the clearance between the knife blades. A drive linked mechanically with the endless chain carries it along the frame, and a gear turns one frame part about the horizontal axis of the articulation that connects the frame parts. The device is used to remove slag from the surface of molten metal in a furnace. The device is adequately serviceable and is convenient to maintain. Hard manual labour is reduced. Small-sized slag is produced suitable for use as a construction material without additional crushing. No metal is lost with the slag.

Title: Folding bicycle with three part frame - has top bar forming rear fork and steering column and bottom bar folding against it
IPC: B62K15/00
Filed: 1975-06-24
Abstract: The folding bicycle is of normal dimensions when in use, and its frame is in three parts. The first (1) is a bar, concave at the lower end and forming the rear wheel fork (A), pivoting at the upper end (B) on the top of the steering column (3). A second bar (2) supports the pedal sprocket and pivots on the first one at the rear wheel hub, which it couples detachably to the base of the steering column. The third part is the steering column itself. When assembled, the three parts form a triangle, with the corners at the rear hub and the top and bottom of the steering column. To fold, the second bar is detached from the steering column and swung up against the first bar, after which the column is swung against the second bar.

Title: Discharger for trailing hopper suction dredger - has compressed air blown through excess water in overflow trough to eliminate air bubbles
IPC: E02F7/04
Filed: 1975-08-26
Abstract: The method for discharging muddy water from a hopper dredger comprises overflowing excess water from the hopper to an independent trough, flowing the excess water in the trough through an irregular path and maintaining the excess water in the trough for a time period sufficient that air bubbles are removed, and discharging over board the excess water from the trough to an area below the water line of the dredger. Compressed air is blown into the excess water as it flows through the overflow trough, for eliminating fine air bubbles in the excess water.

IPC: G04C9/08
Filed: 1976-04-01
Abstract: 1512613 Electronic timepieces DAINI SEIKOSHA KK 1 April 1976 [3 April 1975]  13197/76 Heading G3T An electronic timepiece is provided with a single setting switch which is held closed for more than one second, to retard the time displayed, and which causes the display to advance one step each time it is held closed for less than one second. In Fig. 1, a quartz crystal controlled oscillator circuit 1 feeds a 32768 Hz signal to a frequency divider chain 2. A timing reference pulse train at 1 Hz and appropriate width is produced by a waveforming gate circuit 3 which combines the outputs of divider stages F 1  0 -F 1  5 . In normal operation the timing signal is applied via an inverter 10 and a NOR gate 11 to a time measuring and displaying means 12, e.g. a stepping motor driving hands- OPERATION. To advance the time displayed, a setting switch 13 is closed for less than 1 second a logic "1" signal is fed to the NOR gate 11 by anti-chatter switching circuit 16. NOR 11 consequently cuts off the supply of the timing reference signal to the display. A counter 27 starts to count pulses of the 32 Hz output of divider stage F 1  o and would produce an output pulse at Q on reaching a count of 32 but is reset at the termination of the signal from switching circuit 16 before it reaches a count of 32. Thus outputs of counter 27 and a resetting circuit 28 will remain at "0". At the instant the said signal from 16 terminates, a first pulse generator 34 sets a flip-flop 41 the output of which after inversion at 44 controls AND gates 4 to 7. Consequently a logic "1" correcting pulse P 1  is produced by a NOR gate 9 as soon as the output from divider stage F 10  goes to "0". The pulse P 1  is inverted at 10 and applied to the time display means 12 via the NOR gate 11, the other input of which is logic "0" since the signal from switching circuit 16 had previously terminated. As soon as P 1  ceases, a second pulse generator 45 resets flip-flop 41 and all the circuits resume their normal state. Thus each closure of switch 13 of less than 1 second duration, causes the display to advance one step. To retard the display, switch 13 is closed for more than one second so that the counter 27 will produce an output at Q at the count of 32 and the resetting circuit 28 will reset the divider 2. The timing reference signal Pb is blocked by NOR gate 11 since one input thereof is maintained at "1" by the signal from switching circuit 16. Likewise a pulse produced by waveforming circuit 3 when the divider is reset is also blocked from the display means. Thus while switch 13 is closed the display will not advance. Normal operation is automatically resumed 1 second after switch 13 is opened.

Title: Tubular heat exchanger - incorporates rings between tubes and tube-plate holes, with joints ensuring fluid-tightness while allowing expansion
Inventor: BINET RAYMOND
IPC: F28F21/06
Filed: 1976-05-03
Abstract: A tubular heat exchanger incorporates rings around the tubes where they pass through the tube-plates. The dia. of the holes in the tube-plates is greater than the outside dia. of the tubes. The ring fills the annular space between the tube and the plate. The ring has an outer and an inner groove. Toric joints are fitted in the grooves, ensuring fluid-tightness between the hole and the ring, and between the ring and the tube, respectively. The invention provides a soln. to the problem of ensuring fluid-tight joints between the tubes and the tube-plate while allowing free expansion of the tubes in relation to the shell. The soln. eliminates the disadvantages of existing methods. These disadvantages include risk of corrosion due to electro-chemical effects and complicated constructions necessitating threading, springs, special joints etc.

Title: Hydraulic tappet for IC engine valve operation - has stiff valve spring hydraulically connected to valve stem via floating piston
Inventor: SOUBIS JEAN-PIERRE
IPC: F01L1/16
Filed: 1976-07-29
Abstract: The valve stem of an engine slides in a guide and carries a sleeve at its upper end. A free piston slides in the bore of the sleeve. The annular space above the piston is supplied with engine oil through the hole. As the sleeve is pushed downward by the rotation of the cam, the hole is shut off so that the piston is pushed down by hydraulic pressure. The travel of the free piston is less than the travel of the sleeve since some of the oil can flow into the gap which appears between the free piston and fixed piston. The deflection of the spring is thus reduced, enabling a stiffer spring to be used with a higher natural frequency and so preventing valve bounce.
