[Class 88 (ii).] A keyboard musical instrument as in the parent Specification has a thermionic valve for each note, the circuits from valves of notes of the same name in the different octaves being connected together in parallel, Figs. 1 and 2 (not shown). The output circuits of the groups of notes of the same names either are each connected to its own amplifier and loudspeaker Fig. 3 (not shown), or are each connected to a primary of a multiprimary transformer of which the single secondary is connected to an amplifier and common loud-speaker, Fig. 4 (not shown). Fig. 5 shows a transposing device consisting of a pedal-actuated bar G carrying soft-iron blades I nearer to the cores n of self-induction coils s in the note-circuits. One of two manuals may thus be sharpened to any desired degree to give celeste notes with beats. In Fig. 6 the note circuit for key T1 is closed at contact d1 and connected through the transformer Tr to the moving coil e of a loud-speaker. Sounding of the note however is delayed till a second contact d2 is made, energizing the exciting winding E of the loud speaker. The retardation and the amplitude of the note are carried by an adjustable inductance Si. As open to inspection under Sect. 91 (3) (a) the Specification states that a note may also be introduced softly, avoiding percussion in the loud-speaker, by arranging the key contacts, in the filament heating circuit of the valve with a shunt resistance or capacity to avoid sparking, and that changes of timbre may be obtained by varying the ferro-magnetic saturation of a transformer or a loud-speaker core.

Abstract: 690,561. Measuring reflectivity photo-electrically. EVANS ELECTROSELENIUM, Ltd. and COLLINS, G. C. May 24, 1951 [May 24 1950], No. 13035/50. Class 40 (iii). The reflectivity of a surface is determined by a unit placed on the surface and containing a lamp and two photo-cells, one receiving light reflected from the surface and the other direct from the lamp. As shown, the housing unit consists of a metal housing 27 and an apertured insulating block 26, placed on the surface under test. The two photo-cells 1, 2 are in annular form. The lower one, 2, rests on a brass contact ring 13 on a shoulder of the block 26 and its sensitive surface faces downwardly. Contact with the top of the cell is made with a brass ring 17. The upper cell 1 has its sensitive surface facing upwardly and makes contact with a brass ring 22 which engages with a shoulder 24 on a synthetic resin block 28 which is positioned inside the metal housing. Between the two photo-electric cells " floats," by springs 19 recessed into its top and bottom surfaces, an insulating block 15. To vary the light received on the top surface of cell, the aperture formed by the shoulder 24 is made non-circular. Above it is situated a disc 25 with a non-circular aperture which rotates in a recess in the block 28. The angular position of the disc may be varied by a pin 29 which extends through a slot in housing 27. The relative position of the two apertures determines the quantity of light received on the sensitive surface of the cell from electric lamp 3. The light is directed on to the surface under test through a tube 23a containing lenses the arrangement being such that an image of the upper lens is projected on to the test surface. Tube 23a is joined to a tube 23b which has a reduced threaded part passing through an aperture in photo-cell, and fastened by a nut on the lower side of the cell. The lamp is supported on a three-armed spider 30 mounted on three rods 31. The spider rests on three springs 32 on these rods and milled nuts 33 are provided for vertical adjustment of the lamp. A reflector 5 is provided to increase the light received by photo-cell 1. The photocells are connected in opposition to feed a potentiometer across which a meter is tapped. The instrument is standardized by adjusting the available aperture to give zero output with a white surface in position and the potentiometer to give a fixed reading on the meter with a standard grey surface in position.

Title: Improvements in and relating to fluid pressure operated valves controlling the operation of servomotors
Inventor: BAILEY WALTER WILLIAM
IPC: B60T13/24
Filed: 1963-04-04
Abstract: 992,928. Fluid operated brakes. AUTOMOTIVE PRODUCTS CO. Ltd. March 31, 1964 [April 4, 1963], No. 13422/63. Heading F2F. A valve controlling operation of a servomotor of an air or vacuum-suspended type comprises an actuating rod 6 associated with a piston 11 operable by fluid pressure in the master cylinder and a lever 13 operable by the master cylinder piston 18 in event of a fluid pressure breakdown therein to effect mechanical operation of the actuating rod 6. Two servomotors (not shown) are independently controlled by two valves 52, 61 arranged in tandem in a casing 7 which is attached off-set to the line of the master cylinder bore 9 so that the motor 11 intrudes beyond the end chamber 8 thereof. The lever 13 is a metal plate held at the end of the bore 9 by the reverse side of an end-cup 14 supporting the return spring 17 and has its end bent at 15 so that it pivots on the cylinder wall. In event of a pressure break-down the piston 18 travels beyond its normal stopping point and a projection 19 on its end causes the lever 13 to actuate the rod 6. The casing 7 is divided into two chambers 38 and 39 by an annular flexible diaphragm 35 supporting a tubular bush 36 with a central rubber disc 37. The chambers 38 and 39 each contain a sleeve 41, 42 supported on a flexible diaphragm 43 and slidable through a lip-seal 45 retained by a washer 46 to form two further chambers 47 and 48. Blocks 47a and 48a slide in bores in the sleeves 41 and 42 and limit axial movement of the latter by engagement between shoulders 49 and 50. The outer ends of the blocks 47a and 48a form seatings for disc valves 52 and 61 which are normally closed by springs 54 and 63 so that the chambers 48 and 49 are isolated from the chambers 38 and 39. The chambers 38 and 39 connect with the two servomotors and are themselves interconnected and the chambers 47 and 48 are open to atmosphere (Fig. 1, not shown). The rod 6 and another rod 57 have ball ends 58 which engage in recesses in the blocks 47a and 48a, the end of the rod 57 being supported against the wall of the casing 7. When the rod 6 is moved axially it opens the valve 61 to admit air to the chambers 38 and 48, thereby operating the servomotors. The rubber disc 37, compressed between the blocks 47a and 48a, provides " feel " when the rod 6 is being manually operated to apply the brakes. The master cylinder is pedaloperated. To provide power operation to assist the hand-brake a bell-crank lever 20 is pivoted to a bracket on the casing 7 at 21 engaging one end behind a shoulder 25 on the rod 6 and can be operated by a Bowden cable 30 to move the rod 6 independently of the master cylinder.
