Title: Shutter type digital clock
IPC: G04C17/00
Filed: 1975-06-18
Abstract: 1515709 Digital clocks; alarm clocks TAMURA DENKI SEISAKUSHO KK 18 June 1975 [25 Dec 1974] 25922/75 Heading G3T [Also in Division G5] An alarm clock has a four-digit display comprising shutters which are reciprocated by cams behind sets of openings a to g and h1 in a front plate 50, thus allowing light from lamp(s) within the clock to pass through selected openings to display hours and minutes. The drive cams are advanced intermittently and are coupled to rearwardly extending pins on the shutters by pivoted arms, e.g. ab3, de3, h3, at the top and bottom of the clock. Motor 216 also drives a rotor 64 giving a rapidly changing display to show that the clock is running. The clock is of modular construction using a display block A, illumination block B, and a drive block C. The alarm arrangement uses a three-position switch controlled by a face cam mechanism Fig. 22 (not shown) and a selector shaft (486) which can be set manually to four positions. The latter respectively serve (i) to turn a radio (or television) ON; (ii) to turn it OFF; (iii) to allow it to be turned ON at a pre-set (alarm) time; and (iv) to allow a buzzer to be turned on at the preset time. A "sleep" mechanism is also included for turning the radio OFF after an interval.

Abstract: 842,615. Photographic cameras. GAUTHIER G.m.b.H., A. Aug. 29, 1956 [Oct. 15, 1955], No. 26432/56. Class 98(1) A photographic lens shutter is coupled to an exposure meter, mounted in or on a camera externally of the shutter housing, by means including a movable member projecting into the shutter housing, and includes a ring having a control cam engaging the movable member. This cam ring is connected to the shutter speed setting ring or the diaphragm setting ring by a releasable coupling so that the cam ring and the ring to which it is coupled can be adjusted to different relative positions corresponding to different film speeds. The shutter shown has a diaphragm setting ring 15 and a shutter speed setting ring 16 and a ring 18, rotatable between ring 16 and the shutter front plate 19. This ring 18 has a cam 18a engaged by a movable pin 5 linked to the setting dial of an exposure meter. Ring 18 is also provided with recesses corresponding to different film speeds and each recess can be engaged by a spring loaded pin 43a carried by an arm 15a projecting from the diaphragm setting 15. In use, the pin 43a is first pulled out of a recess and ring 18 rotated alone until the pointer 41a registers with the correct film speed as indicated on a scale 47 carried by ring 18. The diaphragm setting ring 15 and ring 18 are then coupled together by the pin 43a and then the shutter speed and diaphragm stop are chosen.

Abstract: 1,224,466. Controlling electrically. G. K. N. GROUP SERVICES Ltd. June 10, 1968 [June 8, 1967], No. 26343/67. Heading G1N. To control the movement of a tool or flawtesting head 13 from a retracted to an operative position at the approach of a workpiece, a sensing station 18 detects the arrival of the leading edge of the workpiece and, after a time delay which is inversely proportional to the speed of the workpiece less an amount to compensate for the approach time of the tool or head 13, produces a control signal to initiate movement of the tool or head to its operative position. As shown, when the leading edge of a billet passes a photo-cell 16 contacts 16a, 16b are closed energizing relay A/3 to change switches A 1 , A 2 , A 3 . A timing capacitor C 1  is then charged from a D.C. source via resistors R 8 , R 9  and transistor T 1 , at a rate dependent on the output of a tachogenerator T operatively connected to the conveyor for the billets. The capacitor C1 is connected via amplifying transistors T 2 , T 3 , T 4  to the base of transistor T 5  which conducts when the voltage on C 1  reaches a predetermined value, thereby energizing a relay B/1 to initiate movement of a flaw-testing head 13 to its operative position. When the trailing edge of the billet passes the photo-cell, the relay A/3 is de-energized whereupon the capacitor C 1  discharges via transistor T 6  and resistors R 6 , R 7  at a rate dependent on the tachogenerator output. Transistor T 5  becomes non- conducting and the head 13 returns to its retracted position. Allowing for approach time of head. Before the arrival of the billet, capacitor C 1  is precharged via transistor T 6  and switch A 3  to a voltage dependent on the tachogenerator output.

The products are mixed with more chlorine in vessel 20, pass through reactor 23, are mixed with more chlorine in vessel 26, pass through reactor 29 and then pass through the condenser 32 into the receiver 34.  The reaction time in a reactor of the type shown at 80-200 DEG  C. may be 0.1 to 15 seconds and the preferred conditions are 0.45 to 2.3 seconds at 90-120 DEG  C. at substantially atmospheric pressure.

Electrolytic nickel is produced in a 3-stage process in which (1) nickel matte is used as anode and dissolves in an electrolyte containing nickel ions and a weak acid buffer, nickel being deposited on the cathode; (2) the acidity of the used electrolyte is reduced by electrolysis using a nickel-containing anode, the deposition potential and current density applied to the nickel being equal to or less than the discharge potential of hydrogen; (3) removing impurities from the neutralized electrolyte, and re-cycling the resulting electrolyte to stage (1). The neutralizing step (2) by electrolysis produces OH ions, with possibly some small amount of powdered nickel if current densities at the anode and cathode are the same, but nickel hydroxide which remains suspended if the current density at the cathode is high e.g. 5000 A.S.M., as compared with 150 A.S.M. at the anode. The electrolyte is then oxidized by blowing in air to precipitate iron, and copper is then removed by adding nickel powder. These are filtered off, and the weak buffer acid e.g. boric acid, added before returning the electrolyte to stage 1. In this stage some anode slime is formed containing sulphur and small amounts of nickel matte, which is removed and the components recovered. The preferred nickel solution used contains nickel chloride and sulphate with added boric acid.

Abstract: 172,445. Evershed & Vignoles, Ltd., and Needham, J. C. Sept. 21, 1920. Indicating rest or motion; revolution-direction indicators.-Relates to means for indicating at a distance the rest or motion, and direction of motion of any mechanism. The moving coil g of a polarized electrical indicator h<1> is wired to a pair of contacts c, c<1>, through which is discharged a condenser a by means of a rotating brush-carrying arm b and contact rings d, d', which are in turn connected to the terminals e, e<1>. Intermediate blank contacts z prevent short-circuiting. The brush is driven by the mechanism to be observed, the direction of motion of which is therefore shown on the indicator h<1>. To render the indicator independent of the reversal of the supply current, electromagnets wired to the same source of supply at contacts e, e<1> are used; and to dispense with one length of connecting-wire between the indicator and the commutator, resistances r, r<1>, Fig. 3, are introduced on either side of the contact c between it and the supply. A small motor armature may be fitted instead of the moving coil g, giving revolution in either direction of the pointer h. The charging-current may be employed to deflect the pointer, as shown in Fig. 5, by employing two commutators. One carries an arm k friction driven on reversal of the observed mechanism to a fixed position against a stop s or s', so reversing the connections of the moving coil of the indicator; the other k<1> alternately short-circuits the condenser a and charges it through the moving coil.
