Title: Phenolic Resin Compositions with Improved Low Temperature Processing Stability
IPC: C08G8/00
Filed: 1979-06-06
Abstract: Phenolic novolak moulding compositions comprise a phenol- aldehyde resin component wherein (a) 55-90% of available theoretical para-phenyl linkages in the resin chain are bridged to a phenyl group, (b) the carbon chains linked between adjacent hydroxyl-substituted phenyl nuclei have 1-5 carbon atoms, and (c) the phenolic nuclei are capable of chain growth at unsubstituted ortho and para-positions. The resin may be prepared in situ either by the condensation of an unsubstituted phenol, a bisphenol and an aldehyde, or by the sequential reaction of phenol, acetone and formaldehyde. Alternatively the resin component may comprise a blend of (1) a phenol- aldehyde novolak and (2) a bisphenol- aldehyde novolak. The compositions are particularly useful in runnerless injection or cold manifold moulding processes, but can also be used in transfer, compression and injection moulding processes.

Title: Liquid level sensing device
IPC: G01F23/22
Filed: 1979-06-06
Abstract: A liquid level sensor is in the form of a unit comprising a coaxial capacitor open to the liquid and electronic circuitry which detects the change from resonance of a parallel resonant L. C. circuit 45 formed by the capacitor and an associated inductor. The resonant circuit 45 is excited at its resonant frequency under quiescent conditions by an oscillator 50 and the output detected by a detector 46 and discriminated with respect to a reference level by a comparator 47. This operates a change-over relay 49 via a time delay circuit 48 which serves to desensitize the device to slopping of the liquid. <IMAGE>

Patent GB-2030768-A (GB)
Title: Semiconductor store
IPC: H01L21/8242
Filed: 1979-09-28
Abstract: In a semiconductor store comprising a plurality of storage cells each comprising an MOS-selector transistor (AT) which is operated by an operating line (WL) and storage capacitor (CS) which is connected to the selector transistor (AT), a depletion-type varactor is used as the storage capacitor (CS). This reduces the sensitivity of the module to variations in the supply voltage and reduces information loss. If desired, the peripheral load transistors of the store can also be in the form of depletion-type varactors. The depletion- type varactor can be produced either by reducing the thickness of the gate oxide layer (GOS) of the capacitor, or by implanting a conductive channel in the semiconductor substrate surface. <IMAGE>

Title: Self centring clutch withdrawal bearing assembly
IPC: F16D23/14
Filed: 1980-07-03
Abstract: A self-centring clutch withdrawal bearing assembly comprises a guide sleeve 10 of plastics material with a radial portion 9 and a ball bearing mounted on the sleeve. The bearing has an inner bearing ring 2, which, in operation, engages with the clutch and an outer bearing ring 6. The bearing is held on the sleeve 10 by means of a radial portion 8 of the outer bearing ring 6 which is clamped against the radial portion 9 of the sleeve. The clamping is effected by a series of resilient tongues 16 which are moulded integrally with the portion 9 of the sleeve. This allows the portion 8 to move radially under the frictional restraint of the contact with the portion 9 to allow the bearing to centre itself with respect to the clutch as the ring 2 engages with the clutch. The formation of the clamping means, consisting of the tongues 16, integrally with the sleeve 10 simplifies the construction of the assembly as a whole. <IMAGE>

Patent GB-2087516-A (GB)
Title: Butterfly valve
IPC: F16K1/22
Filed: 1980-11-15
Abstract: A butterfly valve is simply and economically manufactured by welding a valve plate (10) to a shaft (11) and then mounting this assembly into an annular, moulded rubber valve body (12) by deforming the latter and inserting the ends of the shaft (11) into aligned holes (14 and 15) in the body (12). After this, a relatively rigid metal ring (16) is fitted over the body (12). The axial length of the ring (16) is less than that of the body (12) so that limited compression of the body (12) is possible when the valve is clamped in use between flanges of a pipe. Compression of the body (12) causes it to expand inwardly to define a seal for the valve plate (10), and for the shaft (11). <IMAGE>

Title: Devices for Checking the Slope of Ladders
IPC: G01C9/28

Thus when face 19 is placed against the front face 29 of a stile 30 of the ladder, the ladder can be adjusted to bring the spirit level bubble 26 to the correct central position to indicate that the ladder is at the desired angle. Similarly face 18 can be placed against flat side face 34 of the stile 30 to check that the stile is in a vertical plane. <IMAGE>

Title: Ceiling fans
IPC: H02K17/02
Filed: 1980-12-15
Abstract: A ceiling fan has a motor of the axial-field type, i.e. the direction of the airgap flux is axial, and the direction the effective conductor is radial. The motor is essentially a single-phase capacitor induction motor, but it possesses a disc shape and planar airgap. The iron cores are strip-wound. The rotor has a skewed cast winding. The stator is located above the rotor, so that the electromagnetic pull produced between the stator and rotor may be utilized to relieve the weight of the rotational parts of the fan. <IMAGE>

Title: Ground Anchors
IPC: E02D5/80
Filed: 1980-12-18
Abstract: An anchoring device comprises a curved pressure resistant plate which is attached to a load- transmitting flexible tendon 14 and is driven into the ground by a shaft 9 at the penetrating end of which is a mechanism connecting to the plate 1 by one or more arms 5. The arms 5 are hinged to the plate at their penetrating or leading ends 6 and have a pivot pin 7 slidably mounted in slots 10 formed at the penetrating end of the shaft 9 or in an extension 8 thereto. During the initial driving of the device the arms 5 are constrained in the slots 10 and the plate 1 is locked in a position of minimum resistance to penetration by a tapered mandril 11/12 operable within the shaft 9, after the initial driving the said mandril is withdrawn from its position 12 within the shaft 9, thereby unlocking the plate 1, and is re-inserted in the shaft 9 in the position 11 in which a tapered leading end engages with the angled edges of the arms 5. The shaft 9 may thereafter be sufficiently withdrawn to release the hinge-pin 6 from the slots 10 and the mandril used to actuate the arms 5 and cause the plate 1 to move into an operating attitude substantially normal to the penetrative axis. <IMAGE>

Title: Monitoring electrically flow of liquid from a container
Inventor: MORGAN GEORGE
IPC: G01F13/00
Filed: 1981-08-29
Abstract: A liquid dispenser which allows entry of air to replace the liquid has a thermistor (TH1) positioned in the path of flow of the air into the dispenser. The thermistor (TH1) is self-heated in a circuit to a temperature higher than that of the ambient air. Only when liquid is actually being dispensed will air flow, cooling the thermistor (TH1) and thus increasing its resistance. Consequent switching of transistor (T1) generates a signal which is passed to a totalisator for monitoring. <IMAGE>

Title: Snooker table
Inventor: TAYLOR GERARD ROY
IPC: A63D15/00
Filed: 1982-02-18
Abstract: A table 1 has spots provided in the usual positions for the coloured snooker balls used in the game of snooker and at the start of a game a pool of red balls are also positioned immediately behind the pink to form a triangle. During play red balls are struck by a cue from a "D" 7 with the object of potting red and coloured balls alternately in one of four pockets 9 provided at the far corners and at the middle of the two sides of the table. For each shot a red ball is removed from a return ball tray 11 or the nearest red ball to the "D" is removed from the playing surface. As each ball falls into a pocket 9 it runs back automatically along sloping channels 10 to the return ball tray 11. By this means a game similar to snooker can be played in a confined space, the player always being situated at the one end of the table and striking successive balls from the "D" 7. <IMAGE>
