Patent GB-684734-A (GB)
Title: O-polyhalophenyl diamidothiophosphates
Inventor: DRAKE LEWIS ROYAL
IPC: C07F9/24
Filed: 1951-03-02
Abstract: The invention comprises O-polyhalophenyl diamidothiophosphates of the general formula <FORM:0684734/IV (b)/1> (wherein n is an integer from 2 to 5 inclusive and each X represents bromine or chlorine), especially compounds containing three halogen atoms, in the 2 : 4 : 5- or 2 : 4 : 6-positions, and the manufacture thereof by reacting thiophosphoryl chloride successively with a polyhalophenol and ammonia.  For the first part of the process, the phenol is advantageously dissolved in a molecular excess of pyridine, or in a mixture of at least an equimolecular proportion of pyridine with an inert solvent such as benzene.  The removal of the pyridine hydrochloride formed prior to the second step is optional, but a preferred procedure consists in using a large molecular excess of thiophosphoryl chloride, filtering to remove pyridine hydrochloride, and recovering the excess thiophosphoryl chloride by fractional distillation under reduced pressure.  The second part of the process is preferably effected by contacting the intermediate reaction product, cooled to 25-40 DEG  C., with a large excess of ammonia (at least 4 mols. per mol. of phenol), by passing gaseous ammonia into the intermediate product or by adding the latter gradually to liquid ammonia.  The products are useful as toxic constituents in miticidal, insecticidal and fungicidal compositions and as addition agents in extreme pressure lubricants.  In examples, the following polyhalophenols are employed: 2 : 4-dichlorophenol, 2 : 4 : 5- and 2 : 4 : 6-trichloro- and -tri bromo-phenol, 2 : 3 : 4 : 6-tetrachlorophenol, and pentachlorophenol.

Title: Combined bobber and hook setting mechanism
IPC: A01K91/10
Filed: 1973-02-07
Abstract: 1401157 Fishing tackle BUSINESS BUILDERS INTERNATIONAL INC 7 Feb 1973 [20 Sept 1972] 6029/73 Heading A1A [Also in Division G1] An automatic striking device is characterised by its detachable float, its visible indicator showing when a strike has taken place and its minor function as a spring balance. The striking mechanism is contained within the plastics body 12 which also supports externally the spherical float, locking being provided by the narrowed bore at 24 springing over the raised part 26. Within the body 12 is a sleeve 65 spring upwards against the shoulder 50 by helical spring 100. Within the sleeve is a shaft 56 with a reduced diameter 52 in its upper part. Two metal balls 68 are located longitudinally by two holes 66, 67 in the sleeve 65 and radially by the core 52 of the shaft and the bore of the body 12. The mechanism is cooked by pulling the sleeve 65 downwards against the spring 100 until the balls ride out against the conical part 40. The mechanism is then locked in the state by an upward movement of the shaft 56 until the full diameter midsection 56 lies between the balls (Fig. 3). A strike is triggered by a downward pull on the hook 62 by the fishing line which causes the tapered part 58 and then the reduced diameter 52 of the shaft to line up with the balls. As a result the balls can move radially inwards and unlock the sleeve which then flies upward under the influence of the spring 100. The body includes an upward extension 30 which has a window 32 and an eye 31, the latter being used together with another in the lower part of the body to attach the fishing line. The upper end of the shaft 54 is coloured and is visible through the window 32 after a strike has taken place. The float is assembled from two plastics mouldings 14, 16 and the assembly includes a skirt 18 which assists in keeping the device upright in the water. The sleeve has a number of circumferential cuts on the outside of the lower part and these are related to the rate of the spring 100 to provide a spring balance for weighing fish attached to the hook 62.

Filed: 1932-03-01
Abstract: 384,144. Clocks. CARRUTHERS, D., 39, High Street, Skipton, Yorkshire. March 1, 1932, Nos. 6138 and 23552. [Class 139.] Chimes; striking mechanism; winding- apparatus, electric.-In clocks having a rotary pin drum 8 for actuating striking and chiming hammers, the drum is released by the going mechanism of the clock and stopped by mechanism actuated by the drum itself (notches 15). The drum may be replaced by cam wheels fixed to a common shaft. The minute hand shaft 1 is driven by a constant speed induction motor 2 through gears 3, 4. Gear 4 is loose on shaft 1 and drives it through ratchet and pawl 5. The hour hand on sleeve 6 is driven by gearing 7. The independent chiming spring (not shown) is attached at one end to the pin drum 8 and at the other end to shaft 1, so that when the drum is locked, its spring is wound up. A lever 9, which normally holds a pin 10 on gearing 11 connected with drum 8, is moved to release the drum by a lever 12 actuated by a pin wheel 13 rigid with shaft 1. When lever 9 is moved, a lever 14 rigid with it has its pin moved out of a notch 15 in drum 8 on to the periphery of the drum so that lever 9 is held and the chiming continues until the pin on lever 14 falls into the next notch 15. Just before the chiming time, lever 9 is released, but the drum is held after a slight rotation by a pin 18 on gearing 11 meeting an abutment 16 on lever 12, until lever 12 is moved. This allows the pin on lever 14 to leave its notch 15. The striking hammer 19, Fig. 3, is normally held raised by a bell-crank lever 20 which is moved during the fourth quarter chime by a pin 21 on drum 8 to allow hammer 19 to fall into engagement with a cam on the drum immediately in front of the striking pins : these effect the striking after the chiming is completed. When pin 21 moves lever 20, it simultaneously releases the striking rack 22, which is restored tooth by tooth by a pawl 23, the latter being lifted with the hammer 19 by a pin and slot connection 24. The first Provisional Specification describes an arrangement in which the chiming drum is driven by an electric motor, of which the circuit-controlling switch is closed by a pin wheel on the minute or hour hand spindle and is opened again by a lever actuated by a cam recess in the chiming drum.
