Patent GB-787672-A (GB)
Title: Method and devices for generating low frequencies
IPC: G10H3/09
Filed: 1955-05-12
Abstract: 787,672. Magnetic recording and reproducing apparatus. SOC. ASSERVELEC. May 12, 1955 [May 21, 1954], No. 13712/55. Class 40 (2). A method of producing single note audio frequencies comprises the recording of at least one discrete frequency on a magnetic record medium in such a manner that it may be reproduced as a continuous note without interruption or break in the continuous wave form. In one embodiment, the recording may be made on a disc or tapered cylinder at a radial position where a complete revolution comprises an exact number of cycles. Fig. 3 shows means by which adjustment for the correct radial position for a particular frequency is made. When a recording has been made by a head 8, reproduc. tion by a head 9 will enable discontinuity to be detected, either by ear or by oscilloscope, which may be calibrated to indicate the radial adjustment to be made by a micrometer screw 12. After erasure by a head 10, a fresh recording will be made at the new distance, and the disappearance of discontinuity verified by a new playback. In a second method in which the recording is made on a cylinder, a recording head 14 is fed by a frequency source 15, and a playback head 16 connected to an oscilloscope 17 which enables the phase of both signals to be brought into unison by means of an adjusting screw 18. When the adjustment has been made the frequency source 15 and oscilloscope 17 is replaced by an amplifier 21, Fig. 6, whereby a desired frequency is continuously re-recorded by head 14 and made available from a line 19. An erase head 22 removes the signal after it has been utilized by the head 16. Specification 783,089 is referred to.

Abstract: Apparatus for the pressure supply of a liquid or paste comprises a pump chamber, a pressure chamber, a resiliently flexible diaphragm separating the chambers and sealing the pump chamber and being capable of being flexed, by <PICT:0653572/III/1> <PICT:0653572/III/2> <PICT:0653572/III/3> fluid pressure in the pressure chamber, towards the interior of the pump chamber in a pressure stroke and of resuming its original attitude in an induction stroke upon relaxation of the fluid pressure, means for connecting the pressure chamber to a source of pressure fluid, a reservoir for the liquid or paste, an inlet connection from the reservoir to the pump chamber, a delivery member mounted for movement between operative and inoperative positions, a delivery connection joining pump chamber to delivery member, an outlet valve for opening or closing the outlet when the diaphragm makes a pressure or induction stroke respectively, an inlet valve for opening or closing the inlet when the diaphragm makes an induction or pressure stroke respectively, fluid pressure-operated means for shifting the delivery member between the two positions, and valve mechanism for controlling the application of fluid pressure to the pressure chamber and to the said means and for producing the pressure stroke of the diaphragm when the delivery member is moved to operative position. Referring to the drawings, adhesive is supplied to the upper surface of the sole member through a tube 8 carrying a nozzle 9 movable to and from the sole and supplying adhesive only when the tube contacts the sole.  The adhesive is contained in closed reservoir 19 and led therefrom through pipe 18 controlled by non-return valve 22 to pump chamber 16 which is connected by pipe 20 and non-return valve 24 to top of tube 8.  Chamber 16 is closed and separated from air-pressure chamber 21 by resilient diaphragm 17. Air under pressure may be admitted to the pressure chamber 21, bulging diaphragm 17 and so forcing adhesive through pipe 20 to nozzle 9 and thence to sole, while on opening the air chamber to exhaust adhesive is sucked from reservoir 19 to chamber 16. Foot pedal 15 operates valve 29 which controls this application and release of pressure.  When the pedal 15 is raised, compressed air flows along pipe 28 through valve 29 to pneumatic piston and cylinder device 14 and holds tube 8 against the pressure of a spring tending to force the tube downwards against the sole, and opens chamber 21 to exhaust.  Depression of pedal 15 applies pressure to diaphragm 17 and also opens device 14 to exhaust so that the spring moves tube 8 to its operative position. Simultaneously, non-return valve 22 closes and 24 opens so that as diaphragm 17 bulges into chamber 16 adhesive is forced past valve 24 and through tube 8 on to the sole. Specification 653,571 is referred to.
