Title: Improvements in gravity escapements and clocks embodying the same
Inventor: PADDON WILLIAM JOHN
IPC: G04C13/06
Filed: 1947-01-03
Abstract: 639,992. Clocks. MAINS TIME CO., Ltd. Jan. 3, 1947, No. 314. [Class 139] A gravity escapement comprises a pendulum 16, Fig. 1, a pallet 17 mounted on the pendulum, a movable mass which when allowed to fall impulses the pendulum and means independent of the pendulum to raise the mass back to its starting point said means operating only after the movable mass has imparted its impulse. A gear .wheel 7 mounted on a spindle 8 is driven through a friction clutch by a synchronous motor 1. The spindle 8 carries a snail cam 9 which cooperates with a vertical detent 10 as described later. A bell-crank lever 13 is pivoted at 12 on the cam 9 and one of its arms is bent over at 13a to form a trip member while the other arm 14 carries a pin 15, 15a the end 15 of which cooperates with the pallet 17 and the other end 15a of which co-operates with a pair of ramps 18 and 19. The arrangement is such that when the snail cam 9 is arrested by the detent 10, Fig. 3, the end 15a of the pin 15 leaves a gate 21 in the ramp 19 and the bell-crank lever 13 rocks clockwise due to gravity. The end 15 of the pin 15, 15a strikes the pallet 17 thus impulsing the pendulum as it moves to the right. The pin 15, 15a then slips from the pallet and the end 13a of the bell-crank trips the detent 10 so that the snail cam 9 is again driven anti-clockwise. The end 15a of the pin 15, 15a meets the surface 18a, Fig. 1, of the ramp 18 and is moved therealong, Fig. 8, by the continued rotation of the cam 9. The pin 15, 15a slips under the foot of the ramp 19 and is then moved up the side 19a back into the gate 21, Fig. 10. The rotation of the gear train 23 for the hands 24, Fig. 1, is thus controlled by the pendulum 16. A wheel 26 driven from the gear train 23 carries a disc 27 on which are mounted two diametrically opposite pins 28, 29 which co-operate with an arm 30 for effecting periodic closure of a mercury switch 31 to send impulses to slave clocks.

Title: Mechanical resonance filter
IPC: H03H9/50
Filed: 1964-01-07
Abstract: 1,042,212. Mechanical filters. TELEFUNKEN PATENTVERWERTUNGSGESELLSCHAFT. Jan. 7, 1964 [Jan. 18, 1963], No. 695/64. Heading H3U. In a mechanical resonance filter comprising a plurality of coupled solid mechanical resonators, the coupling between at least two of the resonators is reduced to reduce the pass-band, this being achieved by providing two coupling means or two groups of coupling means between the resonators which have substantially equal coupling powers but effect couplings which operate substantially in anti-phase. In the arrangement illustrated in Fig. 1, longitudinally vibrating resonators 1, 2 are coupled by flexural vibrations transmitted by wires 3-6. Wires 3 and 4 are effectively an odd number of quarter wavelengths long at the frequency of resonance and wires 5 and 6 are of reduced diameter so as to be effectively increased in length by an odd number of half wavelengths. Since wires 5 and 6 are thinner than wires 3 and 4 a greater number is provided so that substantially equal couplings are effected by the two groups. In Fig. 2 (not, shown) the resonators are excited to torsional vibrations and the coupling wires support longitudinal vibrations, all being of the same effective acoustic length but wires of one set being coupled between antiphase points in the two resonators. Similarly in Fig. 3 (not shown), the resonators are excited to torsional vibrations and one set of wires supports longitudinal vibrations to coupled in-phase points on the two resonators, and a second set consisting of wires of the same acoustic length as those of the first set being coupled to anti-phase points and supporting flexural vibrations.

Title: Improvements in processes for producing pure ascorbic acid
IPC: C07D307/62
Filed: 1954-01-11
Abstract: Ascorbic acid is separated from impurities, e.g. glucides, present with it in a raw material, e.g. a natural extract, by submitting the raw material to a preliminary physical, physicochemical and/or chemical treatment, introducing the resulting material into one phase of a suitable artificial immiscibility equilibrium, bringing this phase into close contact with the complementary phase of this artificial immiscibility equilibrium, whereby the complementary phase is enriched with ascorbic acid, separating the enriched complementary phase, concentrating the enriched phase by evaporation, adding new constituents to the concentrated enriched phase to modify and convert it into one phase of a second artificial immiscibility equilibrium, bringing this phase into close contact with the complementary phase of this second artificial immiscibility equilibrium, and repeating this cycle of separation, modification and contacting operations until a phase is obtained which contains the ascorbic acid in the desired state of purity.  An artificial immiscibility equilibrium is that obtained by mixing two miscible liquids and a solid body soluble in one of the liquids and insoluble in the other liquid, e.g. water, a hydrosolvent such as acetone or ethyl alcohol, and a salt such as calcium chloride or ammonium sulphate.  The complementary phases may be brought into close contact by agitating the two phases whilst passing them in counter-current.

Title: Improvements in or relating to circuit arrangements for private branch telephone exchanges
IPC: H04M/
Filed: 1960-01-08
Abstract: 940,091. Automatic exchange systems. TELEFONAKTIEBOLAGET L. M. ERICSSON. Jan. 8, 1960 [Jan. 12, 1959], No. 777/60. Heading H4K. In a PABX in which a link circuit such as SNR1 is connected to the called line over crossbar switches GVB1, SLVB1, a single wire serves for testing and for holding of the connection, and provision is made in certain circumstances for camping on a busy line and for breaking in. When connection is made to the wanted line, relay T5 is operated in the marker MT and relay S4 in the link SNR1, so that the c wire is connected to differential test relay T2. If the line is idle, the c wire is connected to resistance earth and T2 is inoperative. The marker is released and ringing takes place. The bridges of switches GVB1, SLVB1 are held from break contacts of S5 and G. If the line is busy, the c wire is earthed directly over the multiple and T2 energizes. Relay S5 pulls up and releases switch GVB1, while common relay R energizes and inserts rectifier L in the c wire so that SLVB1 is not held from the busy line. A preferred subscriber may break in by dialling a particular number, whereupon the marker is reconnected and relay T4 therein is energized from the register. Now, when T2 responds to the busy test, S5, R do not energize and the switches are therefore held. Relay S1 operates, holding the c wire when the marker releases, and extends a talking connection to the busy subscriber who is asked to hang up, whereupon S1 falls back and ringing occurs. Incoming calls are set up by an operator, each exchange line terminating in a link, Fig. 4 (not shown), somewhat similar to SNR1. An additional relay (F2) controlled by the operator enables her to make a talking connection to the wanted line. An exchange call can camp on a busy line and is automatically extended thereto when it becomes idle. Relay T1 in the marker MT allows the operator to receive a signal when a camping condition exists on a wanted busy line.
