Patent GB-1287925-A (GB)
IPC: H03B19/14
Filed: 1969-12-16
Abstract: 1287925 Electronic watches CCMPAGNIE DES MCNTRES LONGINES FRANCILLON S A and BERNARD GOLAY S A 16 Dec 1969 [27 Dec 1968] 61168/69 Heading G3T [Also in Division H3] The frequency of an oscillator is varied by controlling the on/off time of a switch T1, T2 arranged in series with a capacitor C2, the arrangement forming part of the resonant circuit L1, C1 of the oscillator. The oscillator comprises a transister T3 operating under class C conditions to periodically charge and discharge capacitor C5 through resistor R4, producing at the output of transistor T4 a train of pulses whose widths may be controlled by varying resistor R4. The pulses control switches T1, T2 and thus vary the proportion of the cycle during which C2 is in parallel with C1. R4 may be a manually controlled resistor or one controlled by an external voltage, e.g. a further transistor. In the latter case the oscillator may be controlled in accordance with the phase difference between the oscillation of this oscillator and a standard quartz crystal oscillator. The oscillator may be employed in an electronic timepiece, and a mechanical resonator, e.g. a tuning fork, may be coupled to the variable reactance by means of an electromechanical transducer.
Patent GB-614950-A (GB)
Abstract: 614,950. Calendars. CHRISTENSEN, A. P. June 24, 1946, No. 18860. Convention date, Sept. 15, 1939. [Class 106 (iv)] A savings-box calendar comprising coaxial drums manually operable by mechanism including a coinfreed locking device and a drum-rotating ratchet lever whose stroke is varied by a cam-disc integral with the month drum and a cam follower is characterized in that the drum-rotating ratchet lever is coaxial with the drums and is geared to the cam-follower by means of a pair of toothed sectors. Insertion of a coin unlocks an operating lever 7 which actuates a lever 8 mounted on the axis 1 of three date drums 2, 3, 4. Actuation of the lever 8 causes a spring 16 to move over a shield 17 till it slips over the edge 19 to advance one tooth ratchet wheels 20, 21, attached to the day-name and month-number drums respectively. A spring 15 then returns the lever 8 to a position of rest determined by its engagement with a toothed sector 11 which co-operates with a cam disc 14, having twelve sectors whose radii vary with the length of the month so that the stroke of the lever 8 varies with the length of the month being longest in the shortest month. Accordingly on the last day of the month a projection 23 on the gear 21 comes into the path of a second spring 22 on the lever 8 so that when it is next actuated the month-number drum 2 is advanced to the numeral " 1," while at the same time a projection 24 on the drum 2 engages a gear-wheel 25 fixed on a second shaft 18, which through a gear chain advances the month-name drum 4 and the cam disc 14.

Title: Vehicle steering column lock
IPC: B60R25/021
Filed: 1979-03-30
Abstract: The locking member 20 of a steering column lock is retained in its releasing position until withdrawal of the key and this is achieved by retaining means in the form of a spring 31, 32 mounted in a recess 33 in the locking member and carrying a projection 30 that projects through an opening 35 in the locking member and engages the barrel 18 of the lock (which is axially movable) to hold the locking member 20 retracted until the barrel moves clear. A second end 40 of this same spring 32 can be used to form the spring that urges the locking member 20 into its locking position and thereby eliminate the need for a separate spring for that purpose. The locking member can have a pivot 23 midway along its length and formed by integral coaxial pegs, with the spring formed by a coil spring mounted on one of the pegs and having oppositely directed limbs 31, 40. <IMAGE>

Title: An arrangement for projecting the image of a sighting mark onto a target
IPC: G02B27/18
Filed: 1980-04-23
Abstract: The invention relates to an arrangement for projecting the image of a sighting mark onto a target e.g. for guiding a missile. The arrangement includes a laser generator (1) which illuminates a sighting mark (5) via an optical fibre (3) and an optical system (6) to form the image of the illuminated sighting mark on the target (8). The optical fibre has a principal purpose of making the beam more uniform transversly than when it leaves the laser generator, thereby ensuring uniform illumination of the sighting mark, and also has a secondary purpose of providing a flexible connection between the generator and the projection system which thereby reduces the bulk of the moving portion of the arrangement. <IMAGE>

IPC: C12N1/20
Filed: 1980-05-16
Abstract: Thermophilic bacteria of the genus Bacillus (e.g. Bacillus stearothermophilus having the ability to produce acetate kinase are continuously cultivated at a dilution rate (D) in the range from about 0.9  mu max to 1.0  mu max wherein D is the dilution rate (1/hr), and  mu max is the maximum specific growth rate (1/hr), to thereby produce bacterial cells having a high content of acetate kinase.
