Patent GB-593106-A (GB)
Title: Improvements in or relating to electrical musical instruments
IPC: G10H3/18
Filed: 1945-06-06
Abstract: 593,106. Reproducing music &c. STANDARD TELEPHONES & CABLES. Ltd., and EARP, C. W. June 6, 1945, No. 14283. [Class 40 (iv)] [Also in Group XXXVIII] In order to obtain a low note from an instrument of comparatively small dimensions, such as a double bass effect from a guitar, the note of the instrument is picked up by an electrical transducer and passed through one or more frequency dividing stages to a loudspeaker. The pick-up may be of electromagnetic type, actuated by an iron armature secured to the string and feeds into an amplifying valve 18 whose output is passed to triode amplifiers 21, 26 in parallel. The normal frequency of the instrument passes from the latter to balanced modulator valves 19, 20 connected in a cathode follower arrangement to output terminals 14, 15. The output of valve 21 passes through a further amplifier 22 to an overloaded limiting valve 23 to produce flat topped waves which are differentiated by condenser 71 and rectifiers 72, 73 into one sharply peaked positive pulse per cycle. These pulses are fed to a multivibrator, comprising cross-connected valves 24, 25 in a known arrangement, and each pulse causes a changeover of the condition of the valves by rendering the non-conducting valve conducting. A complete cycle of the multivibrator thus necessitates two pulses and the output of valve 25 has half the frequency of the input. This output is fed to valves 19, 20 in parallel to produce a modulation of the original tone and a final output is obtained consisting of half the original frequency, together with a series of related harmonics, the amplitude of all of which depends on the amplitude of the original sound wave. The frequency division may be repeated several times by connecting a number of dividing circuits in series. Suggested applications of the invention include the use of a small version of an instrument, such as a guitar, drum or trumpet, and obtaining lower frequencies by subdivision or the use of an electric organ or piano having comparatively few generators or strings, the lower notes again being obtained by subdivision. It is also possible to modify the singing voice by frequency subdivision in a loud-speaker system. Specification 260,067, [Class 40 (iv)], is referred to.

Title: Inhalation/exhalation valves
IPC: A61M16/20
Filed: 1973-03-27
Abstract: 1432234 Fluid regulation F HOFFMANN - LA ROCHE & CO AG 27 March 1973 [27 March 1972] 14561/73 Heading G3H [ Also in Division A5] A device acting as a valve whereby a fluid stream may be conducted from a first connection to a second connection, while a stream flowing in the opposite direction through the second connection is conducted to a third connection, comprises a first duct 2 extending from one end 6 at the first connection to the other end 7 at the second connection, a second duct meeting the first at right-angles and leading to the third connection at its end 8, and a body 9 coaxially supported in the first duct 2 at least partly in the neighbourhood of the second duct, the body 9 having a middle cylindrical part 11 with frustoconical parts 10, 12 at each end and a bore 13 extending from the face of the conical part 12 of the body 9 facing the second connection to a part of the surface of the body 9 opposite the junction between the first and second ducts. In use with a respirator for assisting a patient to breathe, during inhalation air (or another gas mixture) is applied to the inlet end 6 of duct 2. The body 9 is supported by vanes 16, which may be angled with respect to the gas stream to impart rotation thereto. The gas passes through a narrow annular space,  where the flow becomes faster but the pressure falls, so that the pressure near the junction between the first and second ducts is close to the pressure in the second duct (i.e. atmospheric) and there is no appreciable flow of gas from the second duct to duct 2. On the downstream side of body 9 the gas velocity falls but the pressure rises, and the gas flows to the end 7 of the duct 2, which is connected e.g. to the tracheal tube of the patient. On exhalation, the inhalation gas is disconnected from the end 6 of duct 2, and exhaled gas comes from the end 7 of duct 2. Reaching the end 12 of the body 9, the exhaled gas meets a resistance at the narrow annular space between the cylindrical part 11 and duct 2, so that it mainly passes through bore 13 into the second duct, the bore of which has a flared portion 4 and leads to the atmosphere, or to a gas recovery device. If desired, a tube 14 may be provided traversing the duct 2, the part 12 of body 9 and the bore 13, and terminating in the bore of the second duct. While the patient is exhaling, gas is passed through tube 14, and by Venturi effect gas is drawn from the end 7 of duct 2 into the second duct, to assist the patient's exhalation.

Title: Mechanism for the control of the automatic initiation of several successive operations of automatic machine tools
IPC: B23B7/10
Filed: 1953-05-28
Abstract: 737,335. Change-speed control. WERNER AKT.-GES., F. May 28, 1953 [May 29, 1952], No. 14889/53. Class 80 (2). [Also in Group XXII] Mechanism for the control of the automatic initiation of successive operations in automatic lathes or other machine tools effects each successive operation on the disengagement of the previous one, clutch control members for the operations being moved against springs into their engaged positions by latch or pawl members each arranged to be engaged with a control shaft and maintained in the engaged position by locking members lifted out of engagement by the driven part of the machine, the clutch control members carrying initiating members for engaging the latch member for a succeeding operation. A reciprocating table 14 is fed to the right at two different speeds and then returned to the starting position. The table is moved by a screw 13 driven by gearing 12 which is in turn selectively driven by the gear pairs 11, 33; 35, 22, or the reverse gearing 36, 29, 34. The drive is taken from a shaft 10 to which each gear train is clutched as desired by movable clutch elements 45-47. The clutches are operated by pivoted clutch control levers 7, 18, 44, provided with rollers at the lower ends engaged by cams 6, 20, 27 respectively. The clutch control levers are returned to disengaged position by springs 17. The cams 6, 20, 37 are freely mounted on control shafts 3 driven from the shaft 10 by gearing not described. Each cam may be coupled to a shaft 3 by a latch or pawl 2, 4, 38 pivoted to the respective cams but normally held out of engagement with a keyway 41 in the shafts by a trip lever 1, 5, 27 which engages extensions 42 of the latch members. Operation. Trip lever 1 is moved by hand to release the pawl 2 and so set the cam 6 in motion. If a number of cycles of table movement are to be effected arrangements can be made to make successive movements of lever 1 automatically. The cam 6 first moves clutch control lever 7 to engage clutch part 45 and so effect the table drive through the high-speed traverse gears 11, 33. When a dog 15 on the table 14 trips a lever 16, the clutch control lever 7, now unaffected by the cam 6, which has been brought to rest, is released from engagement and returned by spring 17. On returning, the clutch control lever which carries a trip 19 disengages the trip lever 5 and thus the cam 20 is set rotating. Low-speed drive for the table is thus engaged. Reverse motion is finally effected in a similar manner when a dog 23 trips the lever 19. At the end of the reverse run the end surface 49 of the table strikes a trip lever 30 to disengage the drive.
