Abstract: 1,124,154. Making flowmeters. GEORGE KENT (STROUD) Ltd. 21 April, 1967 [18 May, 1966], No. 22010/66. Heading B3A. [Also in Division G1] An induction flowmeter having a small diameter liquid flow pipe, e.g. of the order of “ inch or less, is made from a block of stainless steel through which two perpendicular crossbores 2, 3, Fig. 2, are drilled, one to accommodate the liquid stream and the other the detecting electrodes 7. The ends of the bores are counterbored and threaded at 4, 5. The inner surfaces of both bores are provided with a continuous insulating layer of P.T.F.E. or nylon by introducing the insulating material under pressure into one end of one bore while the other ends are plugged. Subsequently the plugs are removed and holes are drilled through the insulating material. Alternatively the cross-bores may be provided with removable cores around which the insulating material is introduced. The electrodes 7 are each provided with an annular shoulder 8 which when the electrode is inserted in one end of the cross-bore 3 is clamped between an 0-ring 9, an insulating washer 10 and a retaining collar 11.

Title: Improvements in or relating to apparatus for counting differential pressures
Inventor: COCHRANE JOHN NOBLE
IPC: H03K21/02
Filed: 1955-08-02
Abstract: 793,964. Counting apparatus; pressure gauges. BRISTOL AIRCRAFT, Ltd. Aug. 2, 1956 [Aug. 2, 1955], No. 22167/55. Classes 106 (1) and 106 (2). Apparatus for counting the number of occurrences of preselected ranges of fluidpressure differences between a closed container such as an aircraft and the ambient atmosphere comprises, Fig. 1, four differential-pressureoperated diaphragm switches 10, 11, 12, 13 each divided into two chambers 14, 15, the chambers 14 communicating via conduit 16 to the interior of the container and the chambers 15 via conduit 17 to the exterior. Each of the electro-. magnetic counters 26, 27, 28, 29 is arranged so as to commence actuation on operation of its associated pressure switch and to complete actuation and to register when the pressure difference falls to the value which will open the switch 10. This is effected by means of holding relays such as 33. Thus the counter 26 registers the number of occurrences of the lowest pressure difference of 1“ 1bs./sq. inch while 27, 28, 29 register respectively the number of times the pressure ranges 1“-4, 1“-5, 1“-6 are traversed. Alternative circuitry, Fig. 2 (not shown) enables the ranges to be those between the actuating pressure differences of any two of the switches. A constructional design is shown in Fig. 4, where 48, 49 are two of the switches, shaft 43 communicates with the interior of the container and outlet 53 protrudes into the ambient atmosphere. The counters such as 56 are visible through windows such as 62.

Title: Improvements in or relating to automatic signal alarm devices
IPC: H04L15/26
Filed: 1931-07-24
Abstract: 359,541. Selectors responsive to code signals. STANDARD TELEPHONES & CABLES, Ltd., Columbia House, Aldwych, London. -(Gallant, L. C. ; 46, Avenue de Breteuil, Paris.) July 24, 1930, No. 22323. [Class 40 (iv).] A selector comprises a number of time lag relays which time the various components of a code and, in operating, extend the energizing circuit to the next relay of the series, the last relay closing contacts to operate an alarm. When a signal is received R responds and T1 energizes. The first signal must be of between 3¢ and 4¢ secs. duration, and the armatures C, C3 of T1 are slowed, by any known means such as pendulum delay or a constant speed dashpot, so that they make after 3¢ secs. and remain closed for 1 sec. During this period T1 is locked over C independent of R and C3 extends the circuit from contact B of R to T2. When the first signal ceases R falls away and if C3 is still closed T2 energizes. T2 locks to B over a and releases T1. Its armatures C1, C3 are timed to make during and 1¢ secs., and if the next dash arrives during this period T3 energizes, locks up, and releases T2. Further signals and spaces operate the relay chain in a similar way. When the final signal is received F pulls up and the alarm S is operated. If any signal is not of the prescribed duration, the next relay to be operated in the chain is not energized and the system restores to normal.

Filed: 1967-05-15
Abstract: 1,195,432. Reciprocating motors. HORTSMAN CLIFFORD MAGNETICS Ltd. 10 April, 1968 [15 May, 1967], No. 22329/67. Heading H2A. [Also in Division G3] An assembly for an electromechanical oscillator, particularly for controlling a clock movement, comprises a mechanically oscillating non- rotating member 12 of elongated form, e.g. a tuning fork, which oscillates in a plane and is directly attached to an inertia weight 15 attached to one end of a spring 18, the other end of which has means, such as a support block 16, by which it is mounted on a base 11. The spring 18 will readily flex to allow movement of the inertia weight in one direction parallel to the longitudinal direction of the member 12 and in another direction perpendicular to the said direction and parallel to the said plane. Thus vibration of the tuning fork due to centrifugal and other forces is not transmitted or transmitted only in attenuated form to the base 11, so that the frequency of the tuning fork is not substantially affected thereby. The support block 16 is preferably of vibration absorbing material such as nylon. In an alternative construction the tuning fork tines 30, 31 (Fig. 4, not shown) extend upwardly and the spring extends downwardly midway between them. In a further alternative the tuning fork is replaced by a compound reed oscillator as described in Specification 1,184,668, and in another construction a simple reed is used.

Abstract: 412,434. Variable pitch screw propellers. AIVAZ, J., 87, Rue de Monceau, Paris. Feb. 14, 1933, No. 22350. Divided on 411,601 under which a Specification was laid open to inspection under Sect. 91 of the Acts, Aug. 18, 1933. [Class 114.] A variable-pitch screw propeller wherein pitch variation is effected by power such as that obtainable from the propeller shaft has as its varying gear sets of screw and nut mechanism disposed around the axis of the propeller each set comprising an endwise screw member which is directly connected to a propeller blade and preferably by a rack and pinion mechanism. The main screw operating mechanism has end clutches whereby the gear may be automatically disconnected at the two end positions of its motion. The shaft 7 is adapted to be driven by epicyclic gear from the propeller shaft and controlled by braking mechanism and has keyed thereto flanges 9 with ratchet teeth 8, these flanges being constrained inwardly by helical springs. Freely mounted on the shaft is a screw 2 also having end flanges with corresponding ratchet teeth 8. Mounted on the screw is a nut member 3 having on one side rack teeth adapted to engage a pinion 6 on the root of the blade 1. Normally one of the ratchet teeth will be in engagement and upon application of the brake of the epicyclic gear, the screw and therefore the nut receive motion and communicate it to the blade. When the nut has reached the end of its travel, projections thereon abut against the corresponding flange 9 and slide it endwise so that its teeth come out of engagement from those on the screw which is thereby disconnected. Specification 411,601 is referred to.
