Title: Improvements in circuit arrangements for compensating for voltage and temperature changes in electrical timepieces
IPC: G04C3/06
Filed: 1964-12-01
Abstract: 1,093,028. Timepieces; automatic voltage regulation. R.W. REICH. Dec.1, 1964 [Feb. 26, 1964J, No. 23989/64. Headings G3T and G3X. In an electric timepiece in which an oscillating magnetic element induces a voltage in a coil which is applied through current limiting and amplifying means to a driving coil, voltage limiting diode means is connected across the driving coil to maintain oscillation substantially constant. In Fig. 1, driving coils 1 and energizing coils 6 associated with an oscillating balance movement of an electronic clock (not shown) are connected in circuit with a transistor 5. The voltage across the driving coils 1 is kept constant despite variations of battery voltage or changes of temperature by e. g. selenium or silicon rectifiers 2 connected in series in the appropriate sense and in parallel with coils 1. Resistor 3 acts to limit the current which flows when the system is correcting for changes in temperature of the transistor. Modifications are described in which (a) each rectifier element is connected across a portion of the driving coils or (b) rectifiers are also arranged in a similar manner to maintain a constant voltage across the energizing coils.

Title: Improvements in friction clutches and brakes
IPC: F16D23/02
Filed: 1945-09-17
Abstract: 599,462. Friction clutches. CLERK, R. C. Sept. 17, 1945, No. 24005. [Class 80(ii)] [Also in Group XXXIV] In a fluid- or electrically-operated friction clutch, or brake, an auxiliary friction device mounted on one main clutch, or brake, element and co-operating with the other, controls the operating means for the main clutch, or brake, so that the latter can only be engaged when the elements are rotating as substantially equal speeds. An annular U-section electromagnet 10 is fast on the driving shaft 12 and a co-operating armature 13 is splined to the driven shaft 14. An auxiliary annular U-sectioned electromagnet 15 is mounted within the magnet 10 and arranged to have relative rotation which is limited by the fixed stops 16, 17 (not shown) and the pin 18. Insulated contact segments 201, 202, 203, 204 attached to the rear of electromagnet 15 co-operate with supply brushes S1, S2, S3, S4 and the main clutch brushes M1, M2, M3, M4. All the supply brushes are connected through a slip ring 21 to one side of the current source, the other side being connected to earth as is one side of the main electromagnet winding. The auxiliary magnet has two windings 25A, 25B connected to adjacent segments 201, 204, and to earth. In operation, if the speed of the shaft 14 exceeds that' of the shaft 12 when the supply brushes and segments 202, 204 are energised, the auxiliary magnet 15 will be clutched to the armature 13 but restrained by the stop 16, therefore segments 201, 203 will remain dead. If the shaft 12 is accelerated until its speed exceeds that of the shaft 14, the auxiliary magnet will lag and move the segments 201, 204 to connect the brushes M2, M3, M4, M1 with supply brushes S1, S2, S4, S3 respectively and thereby energise the main electromagnet when the shafts are substantially synchronised. This will cause the shafts 12, 14 to be clutched together before the auxiliary electromagnet has moved sufficiently to come against the stop 17 (not shown) and cut off the main clutch current. A second embodiment of the invention shows the electromagnetic clutch described above utilised as a brake for the planet carrier of a change-speed gear, and assisted by the torque-responsive cam action of balls accommodated in conical pockets.

Title: Improvements relating to quick make and break electrical switches, circuit breakers,or like mechanisms
IPC: H01H21/42
Filed: 1944-12-06
Abstract: 584,083. Snap-action switches. DENNIS, J. P., and DENNIS, H. P. Dec. 6, 1944, No. 24353. [Class 38 (v)] A switch has a snap action effected by toggle levers one of which is tubular and encloses a helical controlling spring. Fig.. 2 shows a switch having contact arms 4 carried by a spindle 3 the end of which is loosely mounted in a boss 10 carrying plates 9 forming one of the toggle levers. As shown in Fig. 3 the second toggle lever 6 is pivoted at 11 between the plates 9 and is slotted at the other end to enable it to slide over a pin 12 fixed to the switch casing. The lever 6 is hollow and encloses a spring 8 which abuts against the pin 12 and causes the levers to snap past the dead centre position when the lever 9 is rotated by a handle 20. The latter has a notch 22 the sides of which engage a screw or other abutment 21 fixed to the spindle 18 of the boss 10. Connection between the plates 9 and spindle 3 is made by a disc 15 on the spindle which carries a projection 16 engaging in gaps 17 in the plates. A spring 25 coiled round the boss 10 engages at its ends with the projection 16 and a yoke 24 on the plates 9. Fig. 3 shows the parts when the switch is in the off position. When the handle 20 is turned in a direction to close the switch no movement of the toggles and spindle 3 takes place until the wall 22 of the notch strikes the screw 21. Continued movement of the handle turns the toggle 9, the shoulder 17a of the gap 17 abutting against the projection 16 and causing the spindle 3 to rotate. The spring 8 produces a quick make. When the handle 20 is rotated in the reverse direction the yoke 24 winds the spring 25 while the friction of the contacts 4 with the jaws 5 holds the spindle 3 stationary. As the lever 6 passes the dead-centre both springs 8, 25 combine to produce a quick break.

Abstract: 1365630 Scratch-resistant coating ASAHI GLASS CO Ltd 25 May 1972 24757/72 Heading B2E [Also in Division C3] A substrate, e.g. a transparent plastic, is provided with a scratch-resistant coating by first coating it in vacuo with an inorganic material, then applying a polymerizable compound to the inorganic layer and polymerizing it. The polymerizable compound is at least partly absorbed in the pores of the inorganic layer so that a strong composite coating results. In addition polymerizable monomer or oligomer or a compound such as a silane which is polymerizable by hydrolysis and condensation may be used. In the latter case the inorganic layer may first be treated with a solution of an alkali (e.g. KOH) or an alkali metal salt (e.g. NaClO 4 ), residues of which catalyse the polymerization. Alternatively a catalyst such as benzoyl peroxide for addition polymerisation or n-propylamine for condensation may be applied with the monomer. The polymerisation is then carried out by heating or by exposure to steam respectively. In the examples a polymethylmethacrylate substrate is coated with SiO 1+x  (O# x#1) and then treated with diallylphthalate, diallylglycolcarbonate, glycol dimethacrylate, γ-methacryloxypropyltrimethoxysilane, γ - methacryloylpropyltrimethoxysilane mixed with glycol dimethacrylate, N-triethoxysilylpropyl ethylenediamine or CF 3 (CF 2 ) 5 CH 2  CH 2 -Si(OC 2 H 5 ) 3 , the methacryloxypropyltrimethoxysilane being in one case applied by exposing the coated substrate to the monomer vapour in the absence of any catalyst.
