Title: Improvements in and relating to cylindrical carbon resistance furnaces
IPC: F01P5/02
Filed: 1950-05-08
Abstract: 673,488. Electric resistance furnaces. CESKOSLOVENSKE ZAVODY TEZKEHO STROJIRENSTUI, NARODN I PODNIK. May 8, 1950 [May 31, 1949], No.. 11371/50. Class 39(iii) The incandescent tube in a carbon resistance furnace utilizing a protective or reaction gas is protected against local oxidizing caused by impure protective gas by drying out and purifying the gas and directing its flow so that it does not impinge directly on the exterior surface of the resistance tube. In the Figure, hydrogen is fed into the sight-tube 1 of a pyrometer from where, through a tubular carbon insert 2, it flows via openings 3 into an annular space 6 formed round a resistance tube 5. In passing through the hot carbon insert 2, harmful oxygen or water vapour still remaining in the hydrogen reacts with the carbon to form hydrocarbon and carbon monoxide.

Title: Tapeless venetian blinds
IPC: E06B9/304
Filed: 1919-05-08
Abstract: 149,075. Sutherland, O. May 8, 1919. Venetian blinds; roller-blinds, pawl and catch arrangements for.-Relates to venetian blinds in which the laths are connected together by chains and removable spring clips, instead of the usual ladder tapes. According to the invention, the spring clips are made of wire. The clips G, shown separately in Fig. 3, are made of bent and coiled wire arranged to grip'the laths as shown in Fig. 1. Pins passing through the clips are attached 'to' suspension chains H, which are connected at their upper and lower ends to pins carried by plates F fixed to the rocking-lath E and the bottom lath respectively. The rocking- lath is suspended by chains E<1> passing over rollers mounted in a fixed member A, which supports in bearings a rod B carrying pulleys C, C' on to which wire lifting-cords K are adapted to be wound. The ends of the laths are recessed to allow the cords K to pass freely down to the bottom lath, to which they are attached. The rod B is rotated, to wind the lifting-cords on the pulleys and raise the blind, by means of a cord L. A ratchet-wheel C<2> is provided on the end of the rod B, and is engaged by a check or pawl carried by a lever I, which is pivoted on the end of the member A and is operated by a cord. A spring (not shown) normally holds the check in engagement with the ratchet-wheel C<2>.

Title: Tyre curing press
IPC: B29D30/06
Filed: 1966-03-16
Abstract: 1,125,599. Moulding tyres. NRM CORP. 16 March, 1966 [1 April, 1965], No. 11544/66. Heading B5A. In a tyre curing press having a fixed lower mould section 13 and a vertically and laterally movable upper mould section 7, the latter includes a coaxially located tyre loading mechanism including a number of pivoted sector plates 95 which are movable axially and radially whereby when the section 7 is raised and laterally spaced from the section 13 the loading mechanism is lowered so that the plates 95 contact the upper bead of a green tyre located on a stand; the mechanism is then raised to seat the upper bead of the tyre centrally of the upper mould section. The two mould sections are then realigned and an inflated bladder 17 raised into engagement with the inner wall of the tyre. A bladder stripping ram 40 is lowered to contact the bladder whereupon the loading mechanism is operated to disconnect the plates from the tyre. Bladder pressure is then increased, the ram retracted and the press closed to effect curing. After the curing, the ram is extended downwardly to push the bladder into a well in the lower mould section, and the loading mechanism is operated to cause the plates 95 to underlie the upper bead of the cured tyre. As the press opens the ram is elevated, and a discharge conveyer 135, Fig. 15 (not shown), is pivoted in position between the mould sections whereupon the loading mechanism is lowered, the plates 95 radially retracted and the tyre stripped from the upper mould section to fall on to the conveyer. The loading assembly includes an inner tube 44 in which the ram is axially slidable, and an outer tube 57 slidable axially in the inner one and driven by a piston and cylinder assembly 61; the loading assembly is vertically adjustable within the upper mould section by a piston and cylinder assembly 52. Each sector plate 95 is pivoted at 93 to a fitting attached to the inner tube 44, and is connected to a linkage 87, 88 also pivoted to the fitting. The linkage is engaged by a pate 70 connected by rods 64 to the bottom of the outer tube 57. Thus, vertical movement of the outer tube relative the inner one causes the plates to pivot radially. Two uncured tyres may be supported one above the other on a stand adjacent the lower mould section; the upper bead of the uppermost tyre rests on fingers which are radially retractable after the tyre has been loaded on to the press, and then lowered to receive the lower uncured tyre and raise it to the uppermost position for subsequent press loading.

Title: Current limiting system for motor control
IPC: H02P7/292
Filed: 1970-03-11
Abstract: 1,240,975. Control of D.C. motors; protective arrangements. WESTINGHOUSE ELECTRIC CORP. 11 March, 1970 [1 April, 1969], No. 11660/.70. Headings H2J and H2K. The armature A of a shunt-wound motor M is supplied from a bridge rectifier network PS comprising phase-controlled thyristors S1, S2 which are proteeted. by a free-wheeling diode DF. A firing circuit for the thyristors comprises a capacitor C3 providing a base voltage which is clamped through diode D 11 and transistor Q4 to a level determined by potentiometer R 11. A sawtooth voltage which is added to the base voltage begins to rise with the charging of capacitor C4 until a unijunction transistor PUT conducts to supply firing pulses to the thyristors S1, S2. A current overload is sensed by transformer CT which establishes sufficient voltage across resistor R4 to break down a Zener diode D9. Transistor Q3 slightly discharges a capacitor C2 which reduces the clamping value of the base voltage across the capacitor C3. A longer time is required for the sawtooth voltage to reach the unijunction firing level so that firing pulses for the thyristors S1 S2 are delayed. Large overload current conditions are rapidly removed since Zener diode D8 breaks down to drive the transistor Q3 into saturation whereby capacitor C2 is discharged abruptly. The generation of firing pulses for the thyristors S1, S2 is prohibited until corrective action is taken. Capacitors C3, C4, C5 are discharged at the end of each half-cycle of the A.C. input by a network comprising transistors Q1, Q2.
