Title: Improvements in Portable Pumping Apparatus.
IPC: F04C11/00
Filed: 1916-08-25
Abstract: 107,113. Villiers Engineering Co., and Funck, G. Aug. 25, 1916.

Title: Nuclear reactor shutdown system
IPC: G21C7/26
Filed: 1968-03-13
Abstract: 1,200,951. Controlling reactors. CANADIAN GENERAL ELECTRIC CO. Ltd. 13 March, 1968 [25 March, 1967], No. 12241/68. Heading G6C. In the heavy water moderated nuclear reactor, contained in calandria 11, emergency shut down is effected by removal of the moderator water from the tank 11 to the external tank 35, through the ports 36. The helium gas control system 32 normally maintains a differential gas pressure between tanks 11 and 35 so as to retain the moderator within 11. An overpressure in the reactor heavy water coolant circuit opens the rupture disc 39 and initiates operation of device 55 which equalizes the pressure between tanks 11 and 35, causing the moderator to flow into 35. Rupture discs 39<SP>1</SP> and 39<SP>11</SP> operate to protect the calandria against overpressures in the containment building and the system 32.

Title: Improvements in textile drafting apparatus
Inventor: MACKIE JOHN KAY PRINGLE
IPC: D01H5/40
Filed: 1957-04-15
Abstract: 880,871. Textile drafting mechanism. MACKIE & SONS Ltd., JAMES. April 8, 1958 [April 5, 1957], No. 12252/57. Class 120(2) In apparatus for detecting and correcting for irregularity in the thickness of sliver undergoing drafting having means to delay the correction until the irregularity reaches the drafting zone, which means includes slidable members moving around a path between a setting-member controlled by the sliver-thickness and a transmitter controlling the draft, each slidable member has its position controlled by the setting-member and has a surface inclined at a small angle to the path of sliding-motion which acts directly or indirectly on the transmitter. In Fig. 1, a series of slidable members in the form of wedges 30 is arranged on a drum 31 and can move from side to side parallel to the axis thereof: the drum rotates so that the wedges also move between a setting- member 2 and a transmitter 3. The setting- member comprises two flared plates movable from side to side by a weighted member 21 under the influence of a pivoted bell-crank 14 subject to the relative movement of rollers 11, 12 between which the sliver passes. The transmitter comprises a roller 3 linked to a fork 62 governing the position of a belt 63 on two oppositelydisposed cones 60, 61 for adjusting gearing 65 controlling the draft. As successive wedges pass through the member 2 they are set according to the position of that member and in due course correspondingly influence the transmitter 3 through a corresponding series of rods &c., 34, Fig. 3. Each of these has a recess 35 and is spring-biased so that the upper edge of the recess is held in engagement with the inclined face of the corresponding wedge. In this way the latter is locked in the position in which it is set until it passes the transmitter and reaches a member 49 which restores it to the datum position. To remove the locking effect of the rods 34 while the wedges are being set in the member 2, a camsurface 45 is arranged to engage the inner ends of the rods during this time. The rods are arranged in staggered relationship in two rows and the alternate wedges have their inclined surfaces sloping in opposite directions to ensure that movement of a wedge produces a corresponding movement of its rod irrespective of whether the latter is in one row or the other. In another form the position of the wedges and the rods may be reversed; also the wedges may act directly on the transmitter, for which purpose the outer rim of the drum may be cut away so that the transmitter can contact the inclined surfaces. Specification 27304/11 is referred to.

The side plates 13 have stops 27 forming the end bearings for the shaft 19 and providing a limited gap for blade removal. The blade is held on the blade seat 14 by a spring actuated clamp 31 which has a finger piece 32 and is mounted in a guideway provided between the post of the handle and the bottom plate 10b. Insertion of the arm 46 of a rectangular magazine into a guideway 50 displaces the clamp 31. The magazine, Fig. 11, has a feed slide 42 whose dog engages an aperture in and then the end of the uppermost blade to feed it in two steps through a slot 39. Two vertical corrugations 45 in the walls of the magazine locate the blades therein and a leaf spring presses the blade stack upwardly.

Title: Improvements in or relating to electric relaxation oscillators
Inventor: HOUGH GEORGE HUBERT
IPC: H03K3/37
Filed: 1948-05-10
Abstract: 646,749. Pulse generating circuits. STANDARD TELEPHONES & CABLES, Ltd. May 10, 1948, No. 12770 [Class 40 (vi)] A relaxation oscillator comprises two cold-cathode gas-filled tubes having an electrode of one coupled to an electrode of the other so that when one tube fires the other is extinguished land then after a period refires again and extinguishes the first tube. Fig. 1 shows an oscillator comprising coldcathode tubes 1 and 2 coupled by capacitor 9 so that if tube 1 is discharging the anode potential of tube 2 rises and capacitor 9 discharges and then charges through resistors 5 and 6 until tube 2 fires its anode potential falls and tube 1 is extinguished. Capacitor 9 then discharges and the anode potential of tube 1 rises until this tube fires the cycle then being repeated. Output pulses may be derived from across either the anode or cathode loads. Fig. 3 shows a modification in which the cold cathode tubes have trigger electrodes 26, 27 and are enclosed in a single envelope with an ionization screen 28 between the sections. The crystal 41 stabilizes the oscillatory frequency and the double-tuned transformer in the common anode circuit of the tubes which is tuned to the crystal frequency enables a sinusoidal output wave-form to be obtained at terminal 35 and a pulse type output may, in. addition, be derived from across the cathode resistor 38. The transformer may be tuned to select the fundamental or any harmonic of the pulse repetition frequency. In a further modification, Fig. 4 (not shown), the trigger electrodes are biassed negatively with respect to the cathode and the cathode resistor of Fig. 3 is replaced by an output transformer which differentiates the cathode circuit pulses and thus produces a short output pulse each time one of the tubes fires at a repetition frequency which is twice the resonance frequency of the associated crystal.
