Title: Fluid operated clock mechanism
IPC: G04B1/26
Filed: 1974-08-08
Abstract: 1450230 Fluid driven clocks J J SHINKLE 8 Aug 1974 [21 Aug 1973] 34964/74 Heading G3T In a fluid driven clock having buckets 20, 21 carried on opposed arms 17 of a member 16 which is freely mounted to pivot about a shaft 15, the buckets alternately receive fluid from a reservoir 12 via a conduit 25 or 26 depending on the position of an arcuate valve slide 23 fixed to the oscillatory member 16. As shown fluid from a source 5 enters base 34 and passes via ducts 40-42 to the reservoir 12 whence some of it overflows on to flumes 120 and runs down inside transparent housing 10 to a drain aperture 130. The reservoir supplies fluid to a valve block 14 and the slide 23 causes the fluid to be ducted to the appropriate conduit 25 or 26 to fill whichever bucket is raised. The bottom of each bucket is closed by a piston 91 which is raised by a corresponding fixed pin 92 when the bucket is in its lower position, to empty the bucket. A pawl 55 on the member 16 advances a ratchet wheel 50 fixed to the shaft 15. A worm 63 on the shaft drives gears 64-68 and thus an indicator gear 70 which carries, by means of four arms 74, a circular time scale 31. The scale is read against a fixed pointer 32, Fig. 1. A threaded weight 101 on a pendulum arm 100 fixed to the member 16 permits regulation. Fine regulation is also possible by adjusting a needle valve (not shown) to control the fluid level in a trough 113 into which dip vanes 111 of a rotor 110 fixed to the shaft 15.

Abstract: 1397721 Porous ionic membranes ALLIED CHEMICAL CORP 26 July 1972 [27 July 1971] 34992/72 Heading B5B [Also in Divisions C3 and B1-B2] A porous ionic membrane having a fixed charged is obtained by casting a solution having dissolved in it: (a) from 15 to 80% by weight of a matrix polymer, (b) from 10 to 80% by weight of a polyelectrolyte, and (c) at least 2À5% by weight of a cross-linking agent, all percentages being based on the combined weight of (a) + (b) + (c). After casting the film is dried at a temperature below the activation temperature of the cross-linking agent to remove at least a major portion of the casting solvent. The film is then cured by heating it to a high enough temperature to activate the cross-linking agent and so produce an insoluble membrane. In the examples the matrix polymer is polyvinylidene fluoride, polyvinylchloride-acrylonitrile copolymer, polyvinyl alcohol or polyvinyl butyral. The polyelectrolyte may be polystyrene sulphuric acid either free or as the sodium salt, polyvinylmethylimidazolium iodide or polyvinyl sulphonic acid. The cross-linking agent may be a mixture of a complex of BF 3  and monoethanolamine with either epoxide novolac resin or bisphenol-A- epoxide, or it may be trimethylol propane, formaldehyde or glutaraldehyde. Polyvinylmethyl ethyl-maleic anhydride and phenol-formaldehyde condensate serve as cross-linking agents and matrix polymers. Both a copolymer of maleic anhydride and vinyl sulphonic acid and a linear condensate of phenolsulphonic acid, phenol and formaldehyde can serve as polyelectrolyte and cross-linking agent.

Title: A hydro-jet control device for directing the jet stream of a turbo-powered water craft
IPC: B63H11/11
Filed: 1961-09-29
Abstract: 930,567. Jet propulsion stream control. BERKELEY PUMP CO. Sept. 29, 1961 [Oct. 10, 1960], No. 35397/61. Class 114. A hydro-jet control device on a watercraft propelled by a jet stream ejected rearwardly through a discharge nozzle 17 comprises a manifold 18 having horizontally spaced passageways 18a, 18 extending from a central, upper divided opening 23 and terminating at lower jet discharge openings 24, 25 having guide vanes 26 therein and divergently directed at equal angles from a forward direction with respect to the craft, said manifold openings being directed generally forward with respect to the craft when mounted on the stem 14 thereof via a mounting plate 19 having a discharge opening 21 in line with the discharge nozzle 17, and means for providing selective horizontal and vertical positioning the manifold relative to the water craft discharge opening whereby said divided opening may be positioned to direct all, none, or a portion of the jet stream into any of said passageways, thereby controlling the directional movement of the water craft. The manifold also defines a laterally convergent nozzle 27 subjacent the divided opening 23 for directing the jet stream generally rearward when the opening 23 is positioned above the water craft discharge opening whereby horizontal movements of the manifold will laterally redirect the jet stream. Thus when the manifold 18 is in its full raised position with the nozzle 27 directly opposite the opening 21, the jet stream will be directed rearwardly, propelling the craft forwardly. When the manifold is moved horizontally to a position such as in Fig. 5, the convergent sides of the nozzle 27 direct the jet stream to one side, causing the craft to be turned. By moving manifold 18 to its lowermost position, Fig. 8, with opening 23 in alignment with opening 21, the jet stream will be directed through passageways 18a, 18b, thereby being directed forwardly to cause the craft to move rearwardly. If the manifold is then moved horizontally, e.g. as in Fig. 6, the jet streams emitted from openings 24 and 25 will be unequal and the craft therefore be turned as it is moved backward. It is possible to move the manifold to a neutral position, Fig. 7, wherein the jet stream is directed to nozzle 27 and via opening 23 to openings 24, 25 in such a manner that the forwardly directed forces are balanced by the rearwardly directed jet streams, it then being possible to move the manifold horizontally to produce a couple causing the craft to rotate in a relatively stationary position.

Class 100(4) A type printing telegraph apparatus has a shaft driven through a friction clutch, a pawl normally engaging a ratchet mounted on the shaft and preventing rotation thereof, means for withdrawing the pawl from engagment with the ratchet, spring means for advancing the pawl to meet a succeeding tooth of the ratchet and plunger and dashpot for arresting the ratchet and pawl without jarring. Acceleration of the shaft may be controlled by adjusting the clutch pressure and decelleration by adjusting a leak valve in the dashpot. Pawl 15 is pushed out of engagement with ratchet 16 by rocker 53 rocked by link 167. Spring 18 advances pawl 15, until collar 19 abuts dashpot 20, to meet the next tooth on ratchet 16, through plunger 21 and rod 172. Plunger 21 has a non-return valve which closes as the plunger assembly is forced downwards by ratchet 16, thus bringing the assembly to rest by the time plunger 21 reaches its seat on collar 22. During tabulation pawl 15 is disengaged from ratchet 16 for a longer time, consequently ratchet 16 revolves at a higher speed and is not brought to rest by the time plunger 21 reaches collar 22, spring 25 supporting collar 22 is therefore compressed and expands again after arresting the ratchet and pawl to return them to normal rest position. Specification 808,703 is referred to.
