Title: Improvements in or relating to electrical musical instruments
IPC: G10H1/045
Filed: 1948-05-18
Abstract: 656,792. Electrical musical instruments. COMPTON ORGAN CO., Ltd., J., BOURN, L. E. A. May 18, 1948, No. 13423. [Class 88 (ii)] In an electrical musical instrument, wherein the pitch of the notes is determined by the speed of rotation of rotary members 1, Fig. 1, a pitch tremolo is produced by a periodic variation in this speed of rotation. The rotary members 1 are driven by a motor 2 through a belt 3 kept at constant tension by a spring- loaded jockey pulley 6. The speed of rotation of the rotary members 1 is periodically varied by the action on the belt 3 of a second jockey pulley 7 whose axle 8 describes a circular path about the centre of a driving pulley 9. The mutual eccentricity of the two pulleys 7, 9, and hence the amplitude of the tremolo, may be varied by means of the screw 23 and slot 24. The pulley 9 is driven by a belt 11 which is moved, under the control of a stop key, to an adjacent coaxial idler pulley 13, Fig. 3, if no tremolo is required. Specifications 403,444, 433,050 and 448,193 are referred to.

Abstract: 1,115,113. Valves. BAYERISCHE MOTOREN WERKE A.G. 25 March, 1966 [27 March, 1966], No. 13428/66. Heading F2V. A mixing valve for use in the cooling system of an I.C. engine to control the flow from the engine and the radiator to the engine has a temperature responsive element whose surface is exposed more to cooler fluid than the hotter fluid. A pipe 102<SP>1</SP> leads to the engine from a chamber 108<SP>1</SP>, a pipe 105<SP>1</SP> leads from the radiator to a chamber 108<SP>11</SP> and a pipe 107 leads from the outlet of the engine. Interconnected valve members 110, 111 control the flow from the pipes 107, 105<SP>1</SP> in response to a thermal element 109. A valve 113 is also carried by the valves 110, 111 and controls the flow through a by-pass 115. In a modification, the by-pass is omitted and the thermal element extends below the valve member 111. The valve is thus more responsive to the temperature of the fluid from the radiator and this temperature will vary with ambient temperature, thus the fluid in pipe 102<SP>1</SP> will be warmer in winter and cooler in summer.

A fuel/air mixture of richness between 0À75 and 1À70 (the richness of a mixture being defined as the proportion of fuel in the mixture divided by the proportion of fuel in the stoichiometric mixture) is supplied through admission passage 12, whilst a mixture of richness less than 0.75 - which latter mixture may be air alone - is supplied through a duct 13, the terminal portion 14 of which directs this weak mixture away from the sparking plug and has a cross-sectional area less than one third of that of the inlet port 47. The two mixtures are formed in a multiple carburetter, Fig. 3 (not shown), each of the two mixture forming passages of which is controlled by a throttle valve. The two throttle valves may be mounted on a common manually operated spindle or the spindle of the richer mixture throttle valve may carry a cam, Fig.7 (not shown), which actuates the other throttle valve so that the latter is fully open before the cam-carrying throttle valve. The weak mixture throttle valve may be controlled in response to the suction in either of the carburetter mixture forming passages. In a modification, Fig. 5 (not shown), the duct 13 may be formed by an axial passage in the inlet valve stem communicating with a laterally-directed duct adjacent the valve head. The axial passage communicates with the carburetter only when the valve is open, and a peg on the valve guide co-operates with a flat on the valve stem to prevent rotation of the latter.

Abstract: 928,473. Escalators. RHEINSTAHL HAMBURG STAHLBAU EGGERS & FRIEDRICH KEHRHAHN G.m.b.H. April 17, 1961 [May 10, 1960], No. 13724/61. Class 78(1). An obstruction occurring between a moving tread 2 and the fixed comb-shaped plate 3 at the top of an escalator results in the opening of a switch 9 in the driving motor circuit. The obstruction results in the formation of opposed forces A, A<SP>1</SP>, acting between the tread and the transmission chain 4. The moment due to these forces tends to rotate the tread structure 1. The lower tread wheel 6 thus bears with a greater than normal force on a pivotable section 7 of running rail 10 against the action of a spring 8. Similar mechanism may be associated with the upper wheel 5 of the tread for producing the same action when the escalator is running in the reverse direction.
