Title: Improvements relating to instruments for recording vibrations and other physical variables
Filed: 1931-11-25
Abstract: 388,139. Vibration recorders. COOL, H. R., 3397, South Fairmount Boulevard, Cleveland Heights, Ohio, U.S.A. Nov. 25, 1931, No. 32698. [Classes 106 (iii) and 106 (iv).] A device for recording the vibrations of operating mechanism and machines comprises a two-part casing in one part of which a pendulum and stylus is mounted in a movable carrier and an actuator is provided for moving the carrier to produce a record in spiral formation, and in the other part a clock or other motor is provided having a driving element co-operating with a yielding coupling means to drive the actuator. As shown in Figs. 1 and 2, the part 1 of a hinged casing carries a support 5 with a bifurcated hub 6 through which extends a pin 7 forming the pivot for the end portions 8 of a carrier supporting arm 9. To the arm 9 is secured an arm 11 with side portions 12 carrying bearings for the pivot pin 15, Fig. 5, for the boss 16 of a pendulum 19 and stylus arm 17. The carrier arm 9, 11 is also provided with an extension 24 having a notched flange 25, Fig. 7, adapted to co-operate with a cam hoop 27 forming part of an actuator 28. This actuator has a central bearing portion engaging a pin 30 in axial alignment with the axis of the driving element of the clockwork and is held on the pin by a recess and spring device 32. The actuator is provided with a set of spring- controlled pins 33, Fig. 6, any two of which are adapted, in the operative position, to engage the sides of the spring clamping elements 41 that hold the record disc 39 on its supporting table 38, the pins thus form the coupling means between the actuator and the table 38 that is driven by the clock mechanism 36. To absorb shocks the pendulum is formed with a flanged recess which co-operates with a rubber buffer. Backlash between the flange 25 and the cam hoop 27 is prevented by mounting a spring 35 between the pivot pin 7 and a'pin 10 that holds the end portions up to the hub 6. The bearing portions of the pendulum pivot may be constituted by ball races 44, 45 as shown in Fig. 8, the pressure on the bearings being regulated by an adjusting screw 46.

Title: Improvements in sound receivers, particularly for receiving sound waves in liquids
IPC: H01F38/18
Filed: 1921-12-07
Abstract: 172,637. Signal Ges. Dec. 7, 1920, [Convention date]. Subaqueous audible signals.-Receivers for sound signals, particularly for use in liquids, are so constructed that any oscillatory structures are so loosely coupled between themselves or with any detector that the degree of coupling is less than 40 per cent. When there are more than two oscillatory structures, the peaks of the resonance curve of one couple may be brought closer together by the coupling with the other structures. A formula is given for determining the degree of coupling between any pair of oscillatory, structures, but this may also be determined experimentally from the frequencies developed on couplings. In an example, Fig. 1 there are two diaphragms 1, 2 of which 1 only carries a microphone 4. The couplings are those between the diaphragm 1 and the diaphragm 2 through the casing 3, and between the diaphragm 1 and the microphone 4 through one electrode. In Fig. 2, a resonating chamber 9 is connected with the space behind each of the diaphragms 1, 2, by very small holes 7, 8. The resonator 9 is connected with a listening tube 10. In a further example, a ring acting as a detector is attached by a spring to the back of the casing and oscillates in a magnetic field. In each case the various structures which are loosely coupled are tuned independently to the signal frequency, which lies between the peaks of the resonance curves due to the coupling. Specification 150,322 is referred to. The Specification as open to inspection under Sect. 91 (3) (a) states that diaphragm 2, Fig. 2, can be replaced bv a rigid wall and the air chamber between diaphragm 1 and the hole 7 is then constructed as a resonator with less than 40 per cent coupling with the diaphragm 1. This subject-matter does not appear in the Specification as accepted.

Abstract: 816,501. Sealing electric bulbs. BRITISH THOMSON-HOUSTON CO. Ltd. Oct. 25, 1955 [Nov. 12, 1954], No. 32848/54. Class 39(2) [Also in Groups XXIII and XL(a)] A method of sealing the bore of the glass exhaust tube 3 of the envelope 2 of a gas and/or vapour filled electric incandescent lamp, the pressure within which is to be above atmospheric, consists in providing the exhaust tube, at least in the region of the intended seal, with an internal integral coating 7 of a glass having a lower melting point than that of the tube 3, heating the tube 3 in said region so as to cause the tube to become sufficiently plastic to be deformed while withstanding the pressure difference between the inside and outside of the tube, and deforming the tube to close the bore therein. Heated jaws 9 can be brought together against the tube 3 to render it plastic and to deform it. The envelope 2, and exhaust tube 3 can be of sodalime-silica glass and the coating 7 of a boro-phosphate glass of the character described in Specification 592,038 [Group XXIII], and containing, by weight, 28-38 per cent phosphorous pentoxide, 12-22 per cent boric oxide, 8-16 per 'cent alumina, 24-34 per cent of the oxides of zinc, magnesium and barium, and 6-10 per cent alkali oxide, having a thermal expansion characteristic of about 90Î10<SP>-7</SP>, similar to that of the soda-lime-silica glass. According to the Provisional Specification a plug or bead of the lower melting point glass can be arranged within the exhaust tube, preferably at a constricted portion thereof, which is locally heated in the region of the plug or bead to seal the exhaust tube. Specification 369,722 [Group XXIII] also is referred to.

Abstract: 1481383 Valves GENERAL MOTORS CORP 13 Aug 1975 [3 Sept 1974] 33727/75 Heading F2V [Also in Division F1] An I.C. engine induction air flow control device comprises an air flow conduit having a primary air inlet 28 and an air outlet 30 at opposite ends, an auxiliary air inlet (opening 34) connected by a channel (36) Fig. 5 (not shown), to the conduit, a damper 42 having a main portion 54 in the conduit to control air flow through the primary inlet 28 and an auxiliary portion 56 in the channel 36 to control air flow through the auxiliary inlet 34 independent of the rate of air flow therethrough by sliding across the auxiliary inlet. The damper is pivoted to move between a position wherein the main portion 54 obstructs flow through primary inlet 28 and auxiliary portion 56 permits flow through the auxiliary inlet 36 and a position wherein the main portion 54 permits air flow through primary inlet 28 and the auxiliary portion 56 obstructs air flow through the auxiliary inlet 36. The damper 42 is connected to a lever 40 by way of a torsion spring 48, both members 40, 42 being independently pivoted about a pin 44. A bimetal coil 62 acts on the lever 40 through a control arm 58. At low temperature and low air flow rate, the damper 42 occupies the position shown in Fig. 2, obstructing flow through ambient air inlet 28 and permitting heated air to flow through the auxiliary air inlet openings 34. At low temperature and high air flow rate, the damper 42 occupies the Fig. 3 position, with flow permitted through inlet 28 and prevented through inlet openings 34. At higher temperatures, the bimetal coil 62 rotates the arm 58 clockwise allowing the lever 40 to rotate anticlockwise so that the damper 42 occupies the Fig. 3 position at all air flow rates. At intermediate temperatures, the position of the lever 40 is such that at normal flow rates air passes through both inlets 28 and 34 but at high flow rates it passes only through inlet 28 because the auxiliary portion 56 of the damper 42 closes the inlet openings 34.
