Title: A device for testing the frequency characteristics of film-recorded sound
Filed: 1933-12-18
Abstract: 430,097. Measuring frequency characteristics of sound-record tracks. CRICKS, R. H., 159, Wardour Street, London. Dec. 18, 1933, No. 35506. [Class 40 (ii)] [See also Group XXXVI] Frequency characteristics of sound tracks recorded photographically on film strips are measured by converting the modulations of the track into electric currents and measuring the frequency components. thereof. The film is pressed on to roller 7 by rollers 8, 9 and is guided by roller 10 between a light source 14 and photo-electric cell 12 contained in a housing 11 formed with a channel groove 13. The current from cell 12 is fed through an amplifier, filter and detector to a voltmeter 17. The motor 2 is preferably run at speeds less than the speed at which the film was made, and by this means, and by the provision of different filter circuits, the frequency components can be measured. The motor is regulated by series and shunt resistances, a stroboscope disc 27 illuminated by a neon lamp 29 being provided for checking the speed. Losses occurring during printing and developing of the film can be ascertained by comparison with standard sound tracks built up non - acoustically or otherwise, for example, by a rotating chopper-wheel.

Title: Improvements in and relating to intaglio printing machines
IPC: B41F9/06
Filed: 1938-12-07
Abstract: 522,397. Printing - machines. SCHNELLPRESSENFABRIK KOENIG & BAUER AKT.- GES., and KLINGLER, K. Dec. 7, 1938, No. 35734. [Class 100 (ii)]  Inking- apparatus. In an intaglio printing machine, the upper longitudinal edges of the ink trough 2 are disposed close to the cylinder 1 to leave gaps 6, 7 through which the ink is forced under pressure, the width of the gaps being substantially equal to the thickness of ink film to be applied to the cylinder. The thickness of this film may be varied by adjusting the height of the trough 2, e.g., by worm and rack gear. The upper edges of the trough may be provided with a protective covering of an artificial resin or may be provided with longitudinal bars of the same material. Ink is supplied to the trough by a pump and pipe 10 surplus ink returning by a pipe 16 to a reservoir. A horizontal perforated plate may be arranged in the trough to distribute the ink uniformly. The trough 2, cylinder 1 and doctor blade or blades may be enclosed in a housing 14 the upper portion of which is closed by cover plates 30, 31 pivoted to links 34 so that they can be moved laterally before being turned upwardly so as to clear the web 36<SP>1</SP>. Two doctor blades may be provided for use according to the direction of rotation of the cylinder. One or both walls 20, 21 of the housing 14 may be readily removable and for this purpose the wall carries pivot pins which may be axially moved against spring pressure to withdraw them from the pivot sockets in the adjacent stationary parts of the housing.

Title: Improvements in automatic electrical circuit-breakers
IPC: H01H71/52
Filed: 1932-12-20
Abstract: 415,129. Electrically-tripped switches. CRABTREE, J. A., Endwood, Little Aston Park, Sutton Coldfield. Dec. 20, 1932, Nos. 35911/33, (divided on 415,393), and 12481/33. [Class 38 (v).] Circuit-breakers of the type in which the contacts are mechanically locked in the closed position, comprise a closing and locking toggle mechanism which has articulated connection with a resetting handle and is maintained in locking condition by a release - operable trip - catch. The latter is adapted to function as a toggle-anchorage or fulcrum that enables the contacts to be closed and locked by toggle action during the switch-closing actuation of the said handle. The movable contact B is mounted on a spring-arm Bland acted on by a roller b<2> on a lever b, which is pivoted at b<1> to a frame D (shown dotted) in which is also pivoted at C<1> the operating handle C. Pivoted to the latter at a<3> and to lever b is a main toggle a, a<1>, to the common pivot a<2> of which is connected an auxiliary toggle e, f, of which member f is a lever pivoted at f<2> in the frame D and provided with an arm f<3>, co-operating with a latch part g<1> of a trip-catch g for keeping the breaker closed. g is pivoted to D at g<2> and urged by a spring g<3> into the position shown in Fig. 1, in which an overhead plunger i can knock up the arm g<5> or a thermal release such as a bimetal strip h can deflect an arm g<4>. When g is deflected, the spring arm B<1> causes the collapse of the toggles (Fig. 2). Unless the handle C is held manually, it moves to the down position under the action of a light spring connected between the pivot a<3> and a stop, so resetting the lever f behind the latch g<1>; upward movement of C then reclosing the breaker. If the handle C is not moved downwards by the opening of the breaker, it must be moved manually before reclosure can be effected. In a modification, Fig. 5 (not shown), b is dispensed with and a<1> is of insulating material and pivoted to an arm fixed to B<1>.

[Also in Division F2] A typewriter is provided with a one-revolution clutch mounted on a type action lever 1 and comprising a rotary disc 4 which is in continuous contact with a continuously rotating roller 7, the disc 6 which is in frictional contact with a cam 5 accelerating 'the cam, when its lug 7 is released by an arrester 8, to the speed of roller 4 prior to engagement of the cam with the roller. In operation depression of key 12 causes displacement of its associated lever 13 into abutment with a stop 23, whereby pusher 18 biased by a spring 19 into contact with a stop 20 rocks the arrester 8 through an abutment surface 21 and thus releases a lug 7 on the cam 5 to allow the latter to be accelerated to the speed of the roller by the disc 6 which is in rotary contact with the roller. The cam 5 causes the lever 1 to pivot about its pin 2 and actuate a type bar (not shown) by the wire link 3. At the end of one revolution cam 5 is arrested by the arrester 8. Repeated type-actions.-Repeated type-actions are effected by displacement of the stop 23 which is adjustable in the direction of stop 20, whereby the key lever 13 is depressed a further amount to displace pusher 18 into contact with an abutment surface 22 on the arrester 8 so as to rock and intercept the latter until the key 12 has been released.
