Title: Improvements in or relating to transformers, chokes, and the like
Inventor: LEUENBERGER HANS
IPC: H01F30/10
Filed: 1968-11-08
Abstract: 1,220,274. Transformers and inductors. H. LEUENBERGER. 8 Nov., 1968 [14 Nov., 1967], No. 53046/68. Heading H1T. A choke or transformer with a magnetic core having packets of core laminations 2 forming at least a pair of windows 6 comprises at least one winding (7, Fig. 2, not shown) arranged such that the portions or overhangs of the winding beyond the core are disposed as at 14 so as to abut against the core and lie against a sheet metal casing composed of a hood 3 and a base 4. Thin sheets of deformable but hard material compressed to a pre-arranged value may be placed in the air-gaps between the core packets, before the core is clamped between the baseplate 4 and the hood 3. The windings 7 may first be wound flat, assembled in the windows and then the overhangs bent as at 14, or, the windings may be preformed to the required shape. There may be two similar windings in a choke and these may be connected in series. The space between the winding overhang and the casing as well as the core may be filled with an insulating mass with relatively good heat conducting properties. The stampings of a packet of laminations are held together by projections on every lamination to fit into corresponding dents in adjacent sheets (as at 15, 16, Figs. 2 to 5, not shown). A second embodiment comprises for its core two E-shaped packets of laminations (Fig. 2, not shown) and a modification of this has an E-shaped packet of laminations and a T-shaped one to match (Fig. 5, not shown).

Title: Fuel rod pressurization
IPC: G21C17/06
Filed: 1975-12-30
Abstract: 1511860 Fuel elements EXXON NUCLEAR CO Inc 30 Dec 1975 [14 Jan 1975] 53134/75 Heading G6C In a method for fuel rod pressurization and for verifying when pressurization of the fuel rod has taken place, one end of the loaded fuel rod 12 is inserted and sealed into a pressure chamber 18, whereupon the chamber is evacuated. Then the chamber 18 is pressurized with an inert gas. The fuel rod 12 is then drilled as by means of a laser 20 to provide an opening 14 in the end 16 of the fuel rod in the chamber, whereupon the rod is pressurized with the inert gas present in the chamber. Acoustic transducers 28, 30 are attached to the fuel rod 12 at predetermined locations externally of the chamber 18 for monitoring any noise which occurs during the pressurization process, which is transmitted through the metal walls of the rod to the transducers. The transducers 28, 30 generate electrical signals which are proportional to the amplitude of the noise sensed and by observing the signals a calibration of the activity going on can be maintained. A pressure transducer 36 is connected with the pressure chamber 18 for monitoring the status of the pressure in the chamber and providing an output signal which is proportional to the pressure. The acoustic and pressure signals are processed through appropriate electronic circuitry 38 to 50 and recorded in analog (45) and digital (50) fashion for providing a comparative indication as to when the necessary steps for pressurization of the fuel rod have been accomplished.

Abstract: 1452559 APC systems HASLER AG 10 Dec 1974 [20 Dec 1973] 53391/74 Heading H3A In an APC circuit including an oscillator 13, a phase comparator 16, a fixed divider 15 and a variable counter 21, phase comparison takes place normally between the reference pulses f 0  and the divider 15 output and a phase pulse m is substituted for the reference pulse if the latter does not appear within a predetermined period before the pulse m. In operation, the counter 21 emits a phase pulse m for setting the flip-flop 24, a reset pulse, a gate opening pulse on line 26 to provide a test window and a pulse to a comparison circuit 22 during each counter setting in the test window. When the reference pulse is early or late as to occur near the edges of the window, the division ratio of 21 is stepped up or down by one step. When the circuit 22 detects that reference pulses are present but not falling within the window, a gate 20 feeding the divider 15 and the counter 22 is blocked for resynchronization of the loop.

Title: Improvements in automatic slack adjustments for drum brakes
IPC: F16D65/56
Filed: 1966-12-07
Abstract: 1,146,969. Internal shoe drum brakes. ALFRED TEVES G.m.b.H. 7 Dec., 1966 [7 Dec., 1965; 14 Dec., 1965; 20 Aug., 1966], No. 54809/66. Heading F2E. An automatic adjuster, for an internal shoe drum brake of the kind having two shoes interconnected at one pair of adjacent ends by an adjustable link slidable in at least one direction (forward or/and reverse directions of travel), consists of sleeves 3 which threadedly engage thrust pins 2 and are rotated in opposite directions by a crown wheel 6, through ratchet teeth 4, 5 on the sleeves and wheel respectively, when the crown wheel is rotated in a direction for taking up slack by means not shown in Fig. 1, the crown wheel being loaded by a spring 7 towards the sleeves 3 to maintain the ratchet teeth in engagement whilst allowing the teeth to slip when the crown wheel is rotated in the opposite direction. In the embodiment of Figs. 1 and 2 (Fig. 2 not being shown), rotation of the crown wheel is effected by push-rods (8, Fig. 2) extending from the respective shoes and engageable by means of pins (10) carried by head members (24) with recesses in the periphery of the crown wheel, springs (9) being provided to assist movement of the rods during brake release. Adjustment may be arranged to take place either during brake release or during brake application. In the embodiment of Figs. 3-5 (not shown), a ring (15) carried by one of the sleeves (12) engages a pin (13) carried by the crown wheel to effect rotation of the latter in response to axial sliding of the link formed by the sleeves and thrust-pins during braking, e.g. in the reverse direction of drum rotation, a helical spring (19) being used to return the crown wheel to a normal position determined by a stop when the brake is released, the helical spring also maintaining the ratchet teeth in engagement. A guide pin (18) for the spring is located axially of the crown wheel and may be secured either to a fixed support or to the crown wheel (Fig. 6, not shown). In the embodiment of Figs. 7 and 8 (not shown), the crown wheel (30) is rotated through a friction coupling by a rotatable flange (34) which is connected by a crank lever (36-38), a link and a further lever (40) to one of the brake shoes. The friction coupling consists of a ring (33) carried by the flange (34) and a slidable ring engageable with the interior of the crown wheel, a Belleville washer (49) being arranged between the two rings. A ball coupling is also provided between the flange and the crown wheel and consists of balls (48) engaging inclined recesses (46, 47) such that a re-adjustment of the flange (34) relative to the crown wheel occurs if, during heavy braking with the sleeves consequently resistant to rotation, the flange (34) is rotated more than a predetermined amount. Reference has been directed by the Comptroller to Specification 1,051,210.

Atrial pulses are generated by generator 10 at a rate set by variable resistor 20, each pulse generated causing triggering of a fixed 260 m sec one-shot 30 and of a variable 50 to 250 m sec one-shot 32. At the end of the 260 m sec delay one-shot 30 resets a timing circuit of generator 10 which if, for example, set to give 75 p.p.m. then generator on atrial pulse 540 m sec after the reset. Generator 10 is also reset if detector 14 detects a natural or stimulated ventricular beat but such resetting does not affect the atrial pulse timing except in abnormal circumstances when a ventricular beat may occur after the 260 m sec delay of one-shot 30 lapses; in the latter case the next atrial pulse occurs 540 m sec after. reset of generator 10 by the abnormal ventricular beat instead of 540 m sec after reset by one-shot 30. 50 to 250 m sec, as selected by adjustment of a resistor 34, after triggering of one-shot 32 by generation of an atrial pulse, one-shot 32 triggers generator 36 to produce a ventricular, stimulating pulse unless a timing circuit in generator 36 is reset, and the generator thus inhibited, in response to detection of a ventricular beat during the atrial ventricular delay determined by oneshot 32. Controls 20 and 34 allow independent adjustment of the pacing rate and A-V delay. Specification 1307912 and 1335679 are referred to.
