Title: Sound generating and illuminated whirligig
Inventor: PANGESHIRI HAMIDULLA
IPC: A63B21/22
Filed: 2009-06-17
Abstract: A whirligig, comprises a body member 2 rotatable about an axis, a flexible support means 1 for rotating the body member 2 in a forward or reverse direction, said flexible support means 1 being the sole support for the body member 2 during rotation of the body member, a light source L, a power supply B, and a switch S arranged in a circuit between said light source and said power supply, wherein the flexible support means is operable to turn the switch on and off.

Title: Fine gain adjustment of tuned circuit for UWB receiver
Inventor: CERCELARU SEVER
IPC: H03J3/06
Filed: 2009-07-31
Abstract: A circuit tuneable between first and second frequencies, such as LC circuit 30, fig.3, comprises a gain control circuit 33 operable to control the gain (or Q) of the tuned circuit between the first and second frequencies. The gain control circuit 33 comprises a resistor network having at least two resistor lines connectable in parallel, each resistor line comprising one or more resistors (e.g. 401) and a switch (e.g. 407) operable to select or deselect the corresponding resistor line. The switchable resistor network controls the Q of the tuned circuit ("de-Q"). The resistor lines may be binarily weighted, whereby the three-switch circuit of fig.4 can give eight different resistance values (including open circuit). Logic (not shown) may be configured to control the switches so as to minimise the variation in gain of the circuit between the first and second frequencies. The circuit of fig.4 has a fast settling time and provides performance sufficiently good to allow a single tuning circuit to be used in ultra-wideband (UWB) radio receivers across an entire band group.

Title: Liquid treatment apparatus
Inventor: LYMN PETER PHILIP ANDREW
IPC: C23F1/08
Filed: 2008-01-10
Abstract: Treatment apparatus has up-stream rollers (2) and down-stream rollers (3). Between the rollers are provided a pair of upper and lower treatment zone plates (4, 5), spaced by a gap (6) through which sheet material to be treated can be passed. The plates have grooves (9) occupied by strips defining up- and down-stream even slots (14, 15) for flow of treatment liquid into the gap (6).

IPC: C10B1/04
Filed: 1928-04-05
Abstract: 288,335. Migeon, M. April 8, 1927, [Convention date]. Coking processes; retorts.-In the carbonizing of low grade fuels such as peat, wood or shale, the material is pre-dried by the waste heat of the plant, distilled externally or internally or by both methods at low temperature while undergoing a mixing or kneading movement and then distilled at high temperature in vertical retorts, the distillates in the different zones being collected separately. A dryer 2 is mounted above a chamber 3 containing a retort structure formed of superposed elements 5 each consisting of four radial retorts and stepped from one element to the next, this composite retort leading to four inclined retorts 6 each having at its bottom a distributing chamber 7 which feeds two vertical retorts 8. Coke discharge chambers 9 have rotary disc valves 10. Distillation gas is preheated in a coil 20 and passes through a perforated pipe 22 into the upper retort the charge in which is heated thereby. Combustion products from burners in the base rise through retort chambers 24 and flues surrounding the inclined retorts 6 to the space 28 around the upper retort and to pipes 29 leading to the dryer 2. A series of compartments 33 in the dryer discharge on to the conveyers 35 which deliver the material to valves 36 feeding the retorts 5. Each element 5 of the retort is connected by a common space 40 into which the hot gas pipe 22 passes and each element is displaced in a horizontal plane so that at the bottom a discharge shoot 40<a> is formed. The elements are connected by flanges 41 and rims 42, the joint being made with molten metal. Each retort has a discharge pipe 45 and a pipe 46 which may serve to supply heating gas. The distillates are condensed suddenly, and sudden expansion of the gases into a chamber 50 causes deposition of the dust. One or more of the retorts 8 may be employed as gas producers to supply heating gas for the plant, and when heating shale, coal may be added through a conduit. 65.

Title: Improvements in Process and Apparatus for the Manufacture of Chlorhydrins or Bromhydrins.

Filed: 1919-05-02
Abstract: 126,311. Commercial Research Co., (Assignees of Eldred, B. E., and Brooks, B. T.). May 3, 1918, [Convention date]. Hypochlorous acid; hypobromous acid. - in making chlor- or bromhydrins by the action of hypochlorous or hypobromous acid upon gaseous olefines, the acid is prepared by reaction of halogen gas upon water in the presence of excess of a substance which reacts with hydrochloric or hydrobromic acid but not with hypochlorous or hypobromous acid yielding a solution containing practically no free halogen or hydrochloric or hydrobromic acids. The excees is present during the formation of the chlor- or brom-hydrin. Suitable substances are salts of weak acids such as carbonates, bicarbonates, acetates, or borates, or acid salts of strong acids such as di-sodium phosphate. Insoluble salts such as calcium borate or calcium carbonate in the form of soft limestone or pressed blocks of precipitated chalk may be used. Gases containing mixtures of saturated and unsaturated hydrocarbons such as are obtained by destructive distillation of petroleum products or alcohol may be treated. As propylene is reacted upon first, the operation may be conducted in stages to obtain first propylene chlorhydrin and then ethylene chlorhydrin. Hypochlorous acid is prepared by passing chlorine through inlets H into a chamber B containing granular material, which may consist of calcium borate or calcium carbonate, over which is distributed a solution of a salt of weak acid, such as borax, prepared in a vessel G. The solution of hypochlorous acid passes through water-seals a and falls in a shower through a chamber C through which a current of gas containing olefines passes from an inlet L to an outlet M. The liquid flows into a tank K, in which it is cooled to remove boric acid, and may be passed through the same or a similar apparatus. The chlorhydrin is separated by distillation or by extraction with ether, gasoline, carbon tetrachloride or other solvent. Specifications 22309/10 and 128,635 are referred to.
