Patent GB-2128911-A (GB)
Title: Sand blasting apparatus
Inventor: ALLEN ANTHONY DAVID
IPC: B24C7/00
Filed: 1982-10-22
Abstract: An auger 3 operates in the outlet 4 of a sand hopper 1 to drive sand out of the hopper into a water passage 9 to which water is supplied under pressure to convey the sand to a sanding head 5. Pressurised water is taken into the hopper above the sand from the water supply upstream of the water passage so as to subject the sand in the hopper to a pressure equal or substantially equal to the water pressure in the water passage. The sanding head receives an additional high pressure supply of water which combines with the sand and water from the water passage to produce a high velocity jet of sand and water. Located in the outlet 4 is a plug 8, for example of nylon, fitted with a protective rubber bush and having a bore in which the auger rotates and a communicating transverse bore forming the water passage. <IMAGE>

Title: Electric discharge lamp operating circuit
Inventor: SAMUELS PHILIP RUFUS
IPC: H05B41/04
Filed: 1983-02-02
Abstract: A series ballast inductor L and a power factor correcting capacitor C connected across the input terminals of the lamp operating circuit are coupled through a further inductance L1 connected to the ballast inductor L so as to adjust the resultant series inductance to a value suitable for a sodium lamp (SON), and an igniter circuit is coupled to the further inductance L1. The igniter circuit operates to apply ignition voltage to the sodium lamp (SON) during part of the time that the circuit is supplied with power. Protective circuitry C1 is coupled to the further inductance L1 to block or limit high frequency voltage pulses which could otherwise reach the ballast inductor L. The igniter circuit includes a thyristor Th1 and a capacitor C2 which is discharged resonantly into the lamp through part of the further inductor L1. A thermistor E restricts the current supplied to the igniter circuit so that during starting of lamp operation an internal starter of the lamp can ignite the lamp. <IMAGE>

IPC: A61F5/58
Filed: 1983-02-08
Abstract: A method and device for correcting the arrythmia of stuttering and/or stammering comprises a circuit which supplies pulses at a selected frequency to the user. The pulses may be applied to the user by way of tactile, optical or acoustic excitations. The circuit comprises an integrated circuit (1) powered by a battery (2) and connected as an astable multivibrator by means of an R-C assembly (3, 4), the multivibrator output being applied to a transistor (11) which is connected as a current amplifier. Output from the transistor (11) is applied to an excitation member (12) the form of which depends upon whether a tactile, optical or acoustic pulse is to be applied to the user. The frequency of the pulses can be altered using a variable resistor (7). The electronic circuit can conveniently be packaged in a wrist watch-like case. <IMAGE>

Title: Collating and transferring a flow of elongate bar products
Inventor: KNOTT KELVIN
IPC: B65G47/32
Filed: 1983-04-23
Abstract: In a method, for collating and transferring a flow of elongate bar products, the products 12 arrive one behind another at a collating station in a parallel but non-coaxial flow with their respective corresponding ends substantially in alignment e.g. on conveyor 21, and are picked up by a conveyor which groups the bars into a closely spaced succession without substantially altering their mutual alignment, and the group of bars is then lifted from that conveyor onto a dispatch conveyor 27 which closes up the group and sends it for further treatment, for example for wrapping as a multi-pack. The bars are transferred in groups by means of lifting arm 26 which follows a flat elliptical path. The bars arrive from a wrapping machine, initially in a coaxially aligned flow, which is then turned through 90 DEG  into the necessary end-aligned but non-coaxial relationship. <IMAGE>

Title: Fail-safe speed detection
Inventor: HOLLANDS ROGER DARRELL
IPC: G01P3/488
Filed: 1984-01-27
Abstract: Apparatus for detecting the speed of a moving vehicle, or measuring distance travelled, in a fail-safe manner comprises a magnetic sensor 1 mounted in sensing proximity to a magnetically permeable rotor 2. The sensor has a permanent magnet 7, a core 8 and a pole piece 9; about the core is a sensing winding 12 and a further winding 11 connected to an oscillator 14. Frequency responsive means 15 is connected to the output of the sensing winding to detect the variable frequency signal produced by rotor movement and the signal produced by the further winding and to pass the former signal only when the latter signal is present, thus proving correct operation of the apparatus. Frequency of oscillator 14 may lie above or within that suspected to be produced by rotor motion; in the latter case the frequency will be altered to maintain separation between the two signals. In an alternative embodiment, magnet 7 lies between the two windings 11 & 12 on a common core. <IMAGE>
