Title: Improvements in or relating to the electromechanical determination of forces with a direct digital result
IPC: G01L1/14
Filed: 1962-08-29
Abstract: 985,062. Electric selective signalling. ZELLWEGER Ltd. Aug. 29, 1962 [Dec. 8, 1961], No.33202/62. Heading G4H. In a system for measuring a force the deflection of a spring arm 1, Fig. 1, is measured by transducing means included in the circuit of an oscillator 10, adapted to affect its frequency, the cycles being counted over a given time before and during application of the force,the difference between the counts being representive of the force. The transducer may be an inductive coil 3 the core of which is attached to the arm 1 so as to have a variable air-gap with a second arm 2. As the force increases the induction decreases. The coil 3 is connected in a circuit, Fig. 2,with capacitances 4, 6 and 9 forming an oscillating circuit. The given time is obtained from a reference frequency #3, Fig. 3 which is applied to a counter 22 arranged to close a gate 11 at a predetermined count. A diode switch 12 passes the initial offload signals to a counter 23 and the measurement signals to counter 24. This may be a pawl-andratchet motor,a multi-cathode tube counter or a chain of transistor triggers counting in binary scale. Instead of using two counters the same counter may be used, the first count being entered in a forward direction and the second in a backward direction. The residual count, being the difference represents the applied force. Instead of an inductive coil a variable capacitor may be used, the plates separating by deflection of the arm 1. Both types of transducer may be used together as shown in Fig. 10 connected to a single oscillator or arranged between different fixed arms 2, 8, Fig. 14, and connected to separate oscillators. Two coils 3 and 5 Fig. 11 may be similarly arranged the oscillator outputs being combined in a mixer to produce a difference frequency which is counted as before. The signals to be counted may be mixed with a reference frequency reducing them so that the off-load count is small (positive or negative) or zero. Instead of the above transducers,a resistive strain gauge type transducer may be used fastened along the upper surface of the bar. Additionally a second such gauge may be attached to the lower surface as shown in Fig. 21.

Title: Process for making nipple electrode assembly and joint
IPC: B29C45/27
Filed: 1969-07-01
Abstract: 1,243,538. Electrode nipple-joints. GREAT LAKES CARBON CORP. 1 July, 1969 [2 July, 1968], No. 33288/69. Heading H5H. An electrode section-nipple preassembly comprising an electrode section 7 and a doubleconical nipple 4 is manufactured by screwing an internally threaded ring 1 having a plane surface 2 on to the nipple 4 into such a position that when the nipple 4 with ring 1 attached is threaded into the socket of the electrode section 7 until the surface 2 of the ring contacts surface 8 of the electrode section 7, a clearance 12 is provided between he non-loading bearing flanks (i.e. the flanks furthest from the centre of the nipple) of the threads of said nipple and the threaded socket, threading the nipple 4 and ring 1 into the socket until the plane surface 2 of the ring contacts the surface 8 of electrode section 7, locking the nipple in the socket in this position and finally removing the ring. Thus when this pre-assembly is screwed into another electrode section until the surfaces 8 abut, the non-loaded flanks of the threads of both halves of the nipple will be spaced from the socket threads of the electrode section into which it is screwed. The ring 1 may be externally ring- shaped as shown or square and the surface 2 is preferably perpendicular to its axis. The nipple and ring are so dimensioned that when the ring is hand-tight thereon its surface 2 is at its posit on of maximum diameter. The nipple is locked in position by a foaming material 9 which expands and sets hard. The material 9 may be introduced to the bottom of the socket before the nipple-ring assembly is introduced, a thermally insulating layer being introduced first if the nipple is preheated. The foaming material may be formulations of polyurechane, polystyrene or polyvinyl. The nipple may be locked in position by injecting, cement, paste or binder into the space between the end of the nipple and base of the socket via radial slots in the electrode section or longitudinal slots in the nipple. Radial pins may be used instead to lock the nipple in position.

Title: Improvements in water-softening apparatus
Inventor: MILTON JOHN GEORGE
IPC: C02F1/42
Filed: 1958-10-22
Abstract: 862,619. Ion-exchange. PERMUTIT CO. Ltd. Oct. 22, 1959 [Oct. 22, 1958], No. 33821/58. Class 46. A base-exchange water-softening apparatus comprises a container for the exchange material and a discharge passage controlled by a valve which may be open and so allow water to run to waste, while the container is open to allow solid regenerant to be introduced, the passage running upwards from the container to a level above the top of the bed inside the container and then downwards, and means being provided for breaking the syphon path thus formed and so for preventing syphon action. The water-softening container 1 has two outlets 3, 4 by which liquid leaves ; through the bottom outlet 3 when the contents are being rinsed by downflow, and by the upper outlet 4 when they are being backwashed. The wastepassage unit 19 comprises a rising limb 20 and a down-running limb 7, each contained within a single metal casting. Liquid can enter the rising limb 20, provided either of two ports 8 or 9 is opened by its corresponding valve 10, 11 respectively. Near its top the down-running limb 7 is closed except for a threaded hole 12 which receives the threaded end of a short tube 13, which projects into a transparent plastic dome 14 which is threaded to fit into a threaded recess in the wall of the unit 19. A narrow, hollow, open-ended tube 15 carried by the dome 14 is open to atmosphere at its top, and its bottom projects into the tube 13. The tube 15 thus acts as a syphon breaker to prevent liquid being sucked up the rising limb and discharged into the down-running limb by syphon action when solid is introduced into the container while liquid is being discharged. The head of the tube 13 must be at least as high as the level of the contents of the container. Preferably the top of the dome 14 is about level with the top of the container. The unit 19 also includes a valve 16 which is used only to regulate the supply of liquid when raw water is being fed into the container for treatment. In the modified apparatus (not shown), the down-running limb is constituted not by a passage cast within the container but by a long tube which projects into the dome, and co-operates with a syphon breaker just like the short tube 13 in the apparatus previously described.
