Patent GB-2186558-A (GB)
Title: Container closure
Inventor: SINNOTT KENNETH MARTIN
IPC: B65D53/02
Filed: 1986-02-17
Abstract: A jar (1) has its closure (2) sealingly applied by means of a downthrust to compress a gasket (3). The closure is retained by detent means (not shown). The head load applied to the closure of that jar as a result of subsequent stacking of other similar jars on top of the jar in question is limited by engagement of stop means, in this case, the rim (6) of the closure with an external rib (5) of the jar, so that there is no possibility of permanent deformation of the gasket (3) imparted during such stacking. The arrangement is such that the closure (2) can be applied by simple downthrust, without the need for a twisting chuck, even where the detent means comprise screwthreads. <IMAGE>

Title: Self-clamping gardening implement
Inventor: MCGARRY JEROME
IPC: A01D11/00
Filed: 1986-02-22
Abstract: A hand-operated, self-clamping gardening implement, more especially for use in the soil having two pivoting members 1 and 2 each member comprising a cranked fork end 3 and 4 suitably tapered and shaped to gain access underneath the soil, a foot bar 11 to assist in penetration of the soil and two long operating handles 5 and 6 to assist in clamping and removal of plant undergrowth. Also provided are detachable tooth rake bars 12 used to eject wet soil which may foul the teeth of the fork ends. The rake bars are attached to the upper sections of opposing fork ends at pivot point 13, held in position by springs 14 and are actuated between and along the length of the fork end teeth by the 'scissor action' of the two pivoting members 1 and 2. Foot pressure acting on the rake bar extension arms 15 & 16 holds the bars clear of the teeth during penetration of the soil. <IMAGE>

Title: Sub-frame for a vehicle-transported crane
Inventor: BEILFUSS EGON
IPC: B66C23/78
Filed: 1985-07-18
Abstract: A sub-frame (1') for a vehicle-transported crane with a beam mounted in a live ring (28), capable of pivoting around a horizontal and a vertical axis, which in particular is telescopic and possesses at least two supporting carriers (3') articulated in the region of the live ring (28) by means of an upper (18') and a lower bearing (14'), and capable of being pivoted around a vertical axis (4'), ensuring without any safety hazards a lighter and simple design owing to the fact that above the upper bearing (18') a pair of cylinder-shaped jacket-type supporting elements (22) is arranged between the sub-frame (1') and the supporting carriers (3') , and the axis of the cylinder coincides with the vertical axis (4'), whereby the convex supporting surface is arranged on a cover plate (7') of the sub-frame (1') as a projection (23).

Title: A water faucet with timing device
Inventor: SHEN CHUNG-SHAN
IPC: F16K31/48
Filed: 1986-08-04
Abstract: A coil spring controlled timer 20 is provided in a water faucet comprising a clutch assembly 33,38 mounted between a control rod 31 and a valve stem 43 so as to connect the rod and stem only up to a rotation angle of 90 DEG . As shown rotation of the rod 31 through 90 DEG energises the coil spring and causes stem 43 to move the closure member (which may be a rotary plug 45 or a loose ball (80, Fig. 5)) to its fully-open position. Continued rotation further energises the coil spring but does not change the valve setting. Release of the rod allows the timer to return the valve to its closed position, unless it is locked open by cooperating stop lugs (22, 48, Fig. 4d). The faucet may include an apertured pipe 51 which unseats a closure member 58 of a supply pipe 70 when a connector sleeve 54 is screwed on to pipe 70. <IMAGE>
Patent GB-2179738-A (GB)
Title: Fluid level responsive apparatus
Inventor: TRETT JOHN
IPC: G01F23/296
Filed: 1986-08-20
Abstract: A system for controlling the level of bilge water in a bilge tank includes an acoustic transmitter (2) and an acoustic receiver (4) mounted in spaced relationship on an acoustically inert pad (6) to monitor a space at a predetermined level in a bilge tank. A circuit (10 to 18) monitors the output of the receiver (4) when the transmitter is energised and generates a pump actuating signal for actuating a bilge pump (20) when bilge water enters the space. When the level of bilge water drops so that bilge water is no longer present in the space the pump actuating signal is discontinued and the pump (20) is switched OFF. Time delay means allow for level changes due to the pitching action of the boat to be ignored, so that the pump does not work out of water. Repeated start-stop operation out of the water is also prevented. <IMAGE>

Title: Determining rotational speed using magnetic sensors
Inventor: MOLLENDORF DR MANFRED
IPC: G01P5/07
Filed: 1987-10-22
Abstract: A sensor 13, comprising at least two directional magnetic sensitive elements 14 with sensitive axes at 90 DEG  to each other on a common substrate, is moved relative to a permanent magnet 11 in the homogeneous magnetic field (H) of the latter. Depending on the rotational movement, a sinusoidal voltage variation of a frequency equal to the frequency of the rotational movement is generated in the sensor (13). Furthermore, several sensors (13) may also be used, which are arranged with a certain angle of rotation ( beta ) with respect to each other in such a way that a precisely defined phase relationship ( phi ) is established in the signal voltages of the sensors. In this way, additional pulses can be induced by suitable combination of the signal voltages with the aid of an evaluation circuit (71). Furthermore, it is also possible to detect several movement operations and positions simultaneously and independently of one another. The elements 14 may be magnetoresistors, Hall devices, magnetodiodes or transistors, or inductively operated elements. <IMAGE>

Title: Analogue to digital converter
Inventor: MCNIGHT ANDREW JOHN
IPC: H03M1/42
Filed: 1989-02-10
Abstract: An analogue to digital converter (ADC) generates a digital output word (Q) representing an analogue input signal (VS). The ADC comprises means for generating the most significant bit (Q1) of the output word by comparing the analogue input signal (VS) with a first reference signal (V1) and further comprises means for generating each next most significant bit (Q2 etc.) in turn by using the more significant bit(s) already determined to generate a respective further reference signal (V2 etc.) and comparing the input signal with the said further reference signal. The ADC comprises, in an asynchronous circuit (40), a separate comparator (20-k) for generating each bit (Qk) of the digital output word and a separate continuously operating digital to analogue converter (DAC) (32-k) for generating each such further reference signal (Vk). Each DAC (32-k) has an input (d1 to dk) connected to receive each of the said more significant bit(s) (q1 to qk) from the corresponding comparator. The asynchronous nature of the ADC allows high-speed operation and avoids the need for a bit-frequency clock signal. <IMAGE>
