Title: Clock with an automatic winding mechanism for a motor vehicle
IPC: G04B5/02
Filed: 1954-03-11
Abstract: 751,789. Clocks. MORF, E. March 11, 1954 [March 11, 1953], No. 7149/54. Class 139 [Also in Group XXXI] In an automatically wound vehicle clock the indicating means, the escapement and gear train are in a first casing and the power means and automatic winding mechanism are in a second casing. In the first embodiment the first casing 1, Fig. 4 (not shown), is located on the dashboard and the second casing 3, Fig. 2, on the tube 4 surrounding the shaft 7 of the steering wheel. Movements of the shaft 7 are transmitted to a pulley 17 by a coiled spring 20. The pulley 17 is connected by a one-way pawl and ratchet clutch 18, 14, Fig. 3, to a spindle 9 carrying a pinion 12 which meshes with a gear 22 on the barrel arbor 10. The barrel drives a pinion 24 on a spindle 11 which is connected by a Bowden wire 6 in a sheath 27 to a spindle carrying the first gear of the train to the hands and escapement in the first casing. The groove of the pulley 17 is polished so that when the mainspring is fully wound the coil spring 20 slips and does not rotate the pulley. In the second example the first casing is again located on the dashboard but the second casing is located on the engine above the cam shaft 52, Fig. 7. A cam 65 on the shaft 52 raises a plunger 63 which extends into the casing and abuts a lever 59 pivoted at 60 and urged clockwise by a spring 61. When the mainspring is not fully wound the return movements of the lever 59 effected by the spring 62 are transmitted by a pawl 58 to a ratchet 57 geared to the barrel arbor. The barrel drives a shaft 56 connected by a Bowden wire to the appropriate spindle in the first casing. Any suitable movable element of the vehicle may be used to drive the winding mechanism.

Title: Improvements in or relating to apparatus for measuring electrical resistances of high magnitude
IPC: G01N27/07
Filed: 1960-03-01
Abstract: 894,264. Electrolytic testing apparatus; measuring bridges. WAYNE KERR LABORATORIES Ltd., and CALVERT, R. May 11, 1961 [March 1, 1960], No. 7206/61. Class 37. In apparatus for measuring high resistance, an alternating voltage produces a current in the resistance and a resistive screen surrounding the current-carrying part thereof receives an alternating voltage of the same frequency and phase to establish a potential gradient such that at any point along the resistance the screen potential is equal to the potential of the resistance ; and a resistance measuring means responds to the current in the resistance under test and the voltage applied thereto. An alternating source 20 excites a transformer 22 having a centre-tapped secondary of which one half energizes a capacitance electrode 12 coupled to a conductive liquid, flowing or enclosed in a glass tube 10. A further capacitance electrode 13 is connected over the inner of a coaxial cable 19 to a tap on the primary of an output transformer 27 feeding a null indicator 29, a guard ring 14 surrounds the electrode and is connected to the coaxial outer returned to neutral line 25 joining the centre tap of transformer 22 to the free end of the primary of 27, and a screen 15 of resistive material, e.g. conductive glass, surrounds the tube and interconnects 12 and 14. The other half of the transformer 22 is connected through an adjustable standard resistance 30 to a further tap on the primary of 27. Balance is achieved by adjustment of the taps and/or the standard resistance, and at null the guard ring 27 and the electrode 13 are at the same potential, thus minimizing coupling errors, while the screen 15 and liquid 11 have similar potential gradients to minimize capacitance errors. The resistance of the liquid is in ratio to the standard resistance determined by the secondary ratio of transformer 22 and the primary tap ratio of transformer 27.

Title: Mercury switch
IPC: H01H29/22
Filed: 1973-02-14
Abstract: 1393075 Mercury switches E KELLER 14 Feb 1973 [15 Feb 1972] 7297/73 Heading H1N A tiltable mercury switch comprises an insulating housing 2 of generally tubular shape with rod-shaped electrodes 11, 12 sealed coaxially in end walls and with a constriction 5 forming a baffle which divides the housing into a switching chamber 3 and a storage chamber 4 for partial amounts of mercury 14, 15 which remain in electrical contact with the electrodes 11, 12 at all times. The end 13 of electrode 12 co-operates with the constriction to form an annular flow passage 6 which is contoured with conical approaches 7 and 9 and with a shoulder 8 on the storage chamber side to co-operate with the surface tension of the mercury. On tilting the switch from a horizontal rest position, Fig. 1, to a critical angle α, Fig. 2, the switch-on angle, the mercury suddenly flows over the shoulder 8 to make an electrical connection by merging the two partial amounts and on tilting back to a critical angle #, the switch-off angle, the mercury suddenly breaks at the shoulder 8. The configuration of the constriction in conjunction with the surface tension characteristics of mercury ensures that the switch-on angle a is greater than the switch-off angle # and the switch is particularly suitable for the elimination of false switching under impact conditions or in vibratory situations and for the avoidance of electrode erosion due to arcing.

Title: Oxidation of olefines
Inventor: WOODCOCK CHARLES ALBIN
IPC: B01J23/72
Filed: 1950-03-23
Abstract: In a modification of the process for the manufacture of acrolein and methacrolein by the catalytic oxidation of propylene and isobutene respectively with gases containing molecular oxygen at temperatures between 230 DEG  and 400 DEG  C. by passing the reacting gas mixture in the presence of elementary selenium over a contact material comprising initially copper oxide distributed upon activated alumina, the activated alumina is replaced by natural bauxite.  It is desirable to use a bauxite as carrier which contains only a minor amount of iron compounds.  Other features of the process are described in the parent Specification and the efficiency of the contact material may be increased by heat treatment at high temperatures.  In the example bauxites containing varying proportions of iron are ground, heated and treated with warm aqueous copper nitrate.  The liquid is drained off and the residue is dried and heated.  The yields of acrolein obtained by passing a stream of propylene in air and selenium over the heated contact materials are compared.
