Filed: 1972-09-02
Abstract: 1400288 Detecting surface vibration photoelectrically BRITISH AIRCRAFT CORP Ltd 1 Oct 1973 [2 Sept 1972] 40807/72 Heading G1A Apparatus for detecting vibration in a surface 20 includes a coherent light source e.g. laser 2, a beam-splitter 12 and mirror 14 producing two beams 6, 8 which are converged by lens 16 to partially or fully overlap on the surface so that light scattered from the surface produces time varying interference fringes, which are transmitted via filter 24 and lens 26 to photodetector 30 which produces an output signal of which the frequency depends upon the vibration frequency of the surface. The signal is passed to a headphone set to produce an audible output or may be fed to an oscilloscope. A signal from a calibrated local oscillator may also be fed to the headphones whereby an operator can determine the frequency of vibration more accurately. It is stated that the basic vibration frequency heard by the operator is modified by the amplitude of vibration of the surface to give a frequency modulation thereof. If frequency modulation is introduced into the calibrated local oscillator an operator may obtain a second beat frequency such that when the headphone sound is almost completely nullified the operator will know what is the vibration frequency and amplitude in the area of the surface on which the light beams are focused.

Title: Flow regulating devices
Inventor: DIXON LAURENCE CHARLES WARD
IPC: G21C19/04
Filed: 1962-11-02
Abstract: 1,049,486. Regulating fluid flow. ENGLISH ELECTRIC CO. Ltd. Nov. 4, 1963 [Nov. 2, 1962], No.41538/62. Heading G3H. [Also in Division G6] In a gas cooled reactor, the fuel channels are fitted with nozzles so sloped as to cause a limitation in the subsonic gas flow through those channels from which the fuel element has been removed. The nozzles are connected together by ducts through which gas flows from the nozzle in the channel containing a fuel element to the nozzle in the empty channel. The gas reflow into the latter nozzle disturbs the stream line pattern, increases the flow resistance, and decreases the mass flow through the empty channel. In a alternative form there is no connecting duct between the nozzles but the throat is adjustable to give increased flow resistance in an empty channel. The throat is composed of two parts which are relatively movable along the flow path.

Title: Frequency-modulated transmission of telegraphic intelligence
IPC: H04L27/10
Filed: 1961-11-22
Abstract: 1,012,147. Frequency shift signalling. BUDAVOX BUDAPESTI HIRADASTECHNIKAI VALLALAT. Nov. 22, 1961 [Nov. 23, 1960], No. 41782/61. Heading H4P. In a frequency shift telegraphy system the mark and space frequencies are derived by frequency modulating a carrier frequency (oscillator 3) and are equi-spaced in opposite senses from the carrier frequency. The modulated oscillator output is fed over a filter 4 whose pass-band extends from the mark to the space frequency and transmitted over line 1. At the receiver an optional filter 5 passes only the appropriate channel signals which are amplified and limited at 6 and fed over a terminating set 7 to respective filters 8, 9, in the form of four terminal networks, whose pass bands extend symmetrically from the nominal carrier frequency and include, respectively, the mark and space frequencies. The mark and space signals are in known manner demodulated at 10, 11 respectively and fed to the signal translator 12. The system permits the use of extremely narrow limits between the mark and space frequencies of each channel, and hence a larger number of channels for a given frequency band.

Title: Rotary conveyor for feeding articles e.g. sanitary napkins
Inventor: GEER JAMES GEORGE
IPC: A61F13/15
Filed: 1963-10-23
Abstract: 1,056,879. Folding napkins. KIMBERLY-CLARK CORPORATION. Oct. 23, 1963, No. 41871/63. Heading B8A. A sanitary napkin 12 positioned in a shoot 16 is delivered to the pocket 20 of a rotor 22 by a pusher 28, and as it does so the napkin is folded. Pushers 28. The pushers 28 are each carried by rods 48 carried slidingly on framework 40, 42 secured to shaft 32. Each pusher 28 slides between an inner and outer position under the influence of a spring 96 and stationary cam 98 and moving cam 92. Each pusher-rod 48 has disposed through it a pin 78 which carries bearings 82 and 84 of which 82 co-operates with moving cam 92 and bearing 84 co-operates with fixed cam 98. The spider 40, 42 carrying pusher-rods 48 and pushers 28 rotate at a slower speed whilst the cam 92 is driven at 68 to travel in the same direction but at a swifter speed equal to four times that of the slower speed. The movement both rotational and longitudinal of a pusher 28 is therefore governed by three factors, the slower speed of spiders 40, 42, the higher speed of cam 92, and the fixed stationary cam 98. Operation.-Normally, as the spider 40, 42 rotates, the position of each pusher 28 is governed by the engagement of bearing 84 on stationary cam 98. Cam 98 however has a part missing and at this part the pusher-rod 48 under the influence of spring 96 moves so that bearing 82 contacts the cam 92. The gap in cam 98 is thus met by the engagement of bearing 82 with cam 92. To cushion the movement of the pusher-rod 48 outwards at this point cam 92 is provided with an enlargement 92b and this is timed to take over at the instant that the bearing 84 quits the stationary cam 98. The swelling 92b on the cam 92 now governs the position of the pusher-rod 48 and therefore of the pusher 28 and as the bearing 82 moves down the slope of the swelling 92b pusher 28 moves upwards to engage the napkin 12 and to convey it to the pocket 20. Cam 92 is travelling fast so that it is enabled to cause its swelling 92b to come round again so as to take charge of the movement of pusher-rod 90 and to urge the pusher-rod backwards at the moment that bearing 84 is approaching the other end of the gap in the stationary cam 98. The swelling 92b therefore eases the bearing 84 back on to the cam 98 and at this moment causes the retraction of the pusher 28. Bearing 84 is now engaged with cam 98 and the pusher 28 is in the retracted position ready for another cycle of movement.

A tool holder for use with a removable tool bit 26 has a recess 12 formed therein with at least one abutment face 14 and comprises means 32 disposed solely within the perimeter of the recess and being movable with respect to the abutment face to form a pocket of adjustable size in order to determine the operative position of the tool bit when disposed in the pocket and clamping means 50 to hold the insert in the pocket. The holder may be in the form of a lathe or boring tool shank or a milling cutter body having a plurality of recesses for receiving respective cutting bits. The tool bit is provided with central hole through which the clamping means 50, which is in the form of a threaded member, passes, the head thereof engaging in the bore of the tool bit to hold the bit against the abutment face. Alternative forms of clamping members are described and in a further alternative arrangement the tool bit is clamped by a conventional clamp member which overlies the top surface of the bit. The means for adjusting the size of the pocket may be in the form of a slidable wedge member 166 or a rotatable stop member 116 which can be adjusted and clamped in position whereby the position of the tool bit in the pocket is determined by the relation between the abutment face and the movable member. The position of the wedge member may be determined by calibrations on the tool body.
