Patent GB-2188312-A (GB)
Title: Improvements in or relating to the treatment of waters
Inventor: HATTON WILLIAM
IPC: C02F1/52
Filed: 1987-03-09
Abstract: Water may be treated with blocks of alkali metal aluminate, for example sodium aluminate, produced by the crystallisation of a concentrated aluminate liquor by a process in which the concentration is stopped short of the point at which spontaneous crystallisation occurs (wherein its boiling temperature preferably is less than 135 DEG C) and the liquor is cooled, for example to 112 DEG C, and is seeded with aluminate particles, to cause crystallisation, and solidification. The blocks so produced are of uniform consistency, have good handling properties and can provide consistent pH control for acidic waste waters.

Patent GB-2213666-A (GB)
Title: Amplitude modulators
Inventor: HAWKES HENRY WILLIAM
IPC: H03C1/06
Filed: 1988-12-02
Abstract: In an amplitude modulation arrangement, detection at low modulation depths is facilitated by selecting only those positive and negative going slices of the modulated carrier which exceed respective predetermined limiting levels and combining the selected portions to produce a signal with enhanced modulation depth i.e. reduced carrier components. The positive and negative slices are obtained at 1 with diodes D1, D2 biassed to the desired limits. Further enhancement may be obtained by subtracting an attenuated version of the input to 1 from its output. Unwanted multiplicative and additive modulation is reduced by a preconditioning circuit 9-25. This circuit including a normaliser 25 removes very low frequency amplitude modulation, a particular modulation frequency band or unwanted signals in that band. In case of unwanted modulation on a different carrier, the best frequency component is removed by incorporation of elements 23,24. <IMAGE>
Patent GB-883680-A (GB)
Abstract: 883,680. Ticket-printing machines. JOHANNESBURG TURF CLUB, BROKENSHA, N. L., VILJCON, J. J., MOOLMAN, J., and GOODCHILD, A. G. Nov. 23, 1959 [Nov. 25, 1958], No. 39633/59. Class 106 (3). A ticket-printing and issuing machine for use with betting totalizator equipment comprises a rotary type-drum I around the periphery of which are provided printing elements 3 in pre determined order, selecting means 7 for choosing the characters to be printed on a ticket, and a platen 15 movable towards and away from the drum 1 and normally held in an inoperative position, the platen 15 moving towards the drum 1 during rotation thereof to press portions of a paper strip 22 against successive chosen printing elements as each one moves into line with the paper, the strip 22 moving progressively in accordance with the printing operation. Printing tickets.-The drum 1 is driven from a shaft 5 through an electromagneticallycontrolled clutch 6. In operation, the race number and the numbers of the horses required are set by hand by closing certain switch con-  tacts 7. This connects the corresponding contacts 9 on a rotary switch 8 to the power supply and operates the clutch 6 to set the drum 1 and a wiper arm 10 on the switch 8 in motion. Certain other contacts on the switch 8, corresponding to fixed information are always live. As the wiper arm passes over each live contact, a circuit is made through an electromagnet 14 thus freeing an arm 20 from a spring-urged member 18 which then rotates to move the platen 15 against the paper strip 22. This is then printed with the corresponding information. When the printing is complete, a toothed wheel 23 rotating with the drum 1 acts on a lever arm 27 to return the platen 15 to its inoperative position, the member 18 again being engaged by the arm 20 as the circuit through the electromagnet 14 is also broken (by further rotation of the wiper arm 10). Each chosen element 3 is printed in this way and after one revolution of the drum 1 the clutch 6 is disengaged. The switch 7x which controls the printing of the race number is preset before each race and the other variable information switches are closed by means of keys which are automatically held in the depressed position until a ticket has been printed. Feeding paper.-The ticket strip is stored on a roll 38 and is fed forward by cams 28 and a roller 33 driven from the drum shaft 2. At the start of the printing sequence for a ticket 41, the front end of the paper strip is located at a cutting means consisting of stationary and movable blades 35, 36, the latter being operated by cams 37. As the ticket 41 nears the end of one printing sequence, the cams 28 engage with the roller 33 to move the front end of the paper strip between the blades 35 and 36, and through guides 37, to be in position for printing during the next sequence. At the end of the sequence the blade 36 severs the strip 22 to form a new blank ticket.

Abstract: The distribution of drive power between the left and right auxiliary drive wheels (14RL, 14RR) is automatically varied to improve cornering while the drive power distribution ratio between the main and auxiliary drive wheels is maintained at a suitable value. The control system determines the drive power distribution ratio between the left and right auxiliary drive wheels depending on detected values of vehicle speed; engine r.p.m.; throttle valve or accelerator pedal position, or intake vacuum; gear ratio; lateral acceleration. The vehicle may have a front engine 11 driving the main drive wheels (14FL, 14FR) via differential (13F) and driving the auxiliary drive wheels (14RL, RR) via gear mechanism (15), propeller shaft (16) and rear differential (13R) which comprises two planetary gear assemblies (26H, 26L) and two hydraulic multi-disc clutches (22L, 22R). In each planetary gear assembly (26H, 26L) the sun gear (28H, 28L) engages the housing (18) via a lock clutch (31H, 31L) which comprises a one-way clutch (32H, 32L) and a hydraulic clutch (33H, 33L), the supply to which is varied by the control system. <IMAGE>

Patent GB-2256037-A (GB)
Title: A furnace
Inventor: MCNEILL KEITH RUSSELL
IPC: C03C1/00
Filed: 1992-07-08
Abstract: Toxic waste material containing heavy metals and derived from precipitators and/or scrubbers in the flues of refuse incinerators is made into a batch with glass-forming materials, particularly silica as fly ash and fed to a cold top melter with a special exit construction located within and beneath the part of the cold top melter where the molten vitreous mass is formed. On exit from the furnace the molten vitreous mass is dropped immediately into water within the confines of the furnace exit construction. A sufficient depth of unmelted feed batch is maintained above the molten vitreous mass to prevent vaporised heavy metals and heavy metal compounds passing through the unmelted feed batch to the atmosphere. In consequence, all heavy metals and heavy metal compounds are incorporated in the molten vitreous mass. The feed batch is formed into pellets of 8mm to 25mm diameter and infra-sound is applied across the pellets of the unmelted feed batch to prevent the condensation which forms on the pellets causing them to adhere to one another. <IMAGE>
