Title: Improvements in and relating to drain rod grapples and the like
IPC: E03F9/00
Filed: 1941-11-26
Abstract: 551,037. Friction grip fastenings. KIRBY, T. Nov. 26, 1941, No. 15241. [Class 44] [Also in Group XXX] A drain-rod grapple comprises a ring of jaws 4 pivoted on pins or bolts 3, each jaw having a gripping zone 8 adapted to co-operate with the corresponding part of the next jaw to grip a rod thrust between them, the gripping edges moving apart when pressure is applied to them by the rod and being returned by springs so as to grip the rod. In the construction shown the grapple is mounted on a central member 1 to which a ring 2 is secured by bolts 3, 11. The jaws 4 are four in number, are J- shaped, and are pivoted on the bolts 3. Springs 12 connected to the bolts 3, 11 pass through holes 13 in the jaws and tend to keep them in a central position. The jaws are provided with bevelled or knife edges to form gripping edges and their outer parts 5 are also bevelled at 6 so as to assist in guiding a drain-rod end towards the space between two adjacent jaws. In use the grapple is thrust into the pipe or drain until the free end of a lost drain-rod is reached, this end being guided by the bevels 6 into the space between two jaws. Further forward movement of the grapple causes the jaws to open until the ferrule on the drain rod passes through the jaws. The grapple is then withdrawn, the jaws either gripping the rod itself or jamming against the inner end of the ferrule so that the rod is securely gripped and is withdrawn with the grapple.

Title: Process for the manufacture of 4-hydroxy-1-aminonaphthalene-8-carboxylic acid and of 4-hydroxynaphthostyril
Filed: 1937-06-02
Abstract: 4 - Hydroxy - 1 - aminonaphthalene - 8-carboxylic acid and 4-hydroxynaphthostyril are obtained by combining in a strongly alkaline medium 5 - hydroxynaphthalene - 1 - carboxylic acid with a diazo compound, and reducing the monoazo compound thus obtained. The acid itself may be isolated and may then by treatment with acid be converted to 4-hydroxynaphthostyril, or the solution of the acid resulting from reduction of the monoazo compound may be directly converted to 4-hydroxynaphthostyril by treatment with acid.  In the example, 4-toluidene is diazotized and combined with 5-hydroxynaphthalene-1-carboxylic acid.  Sodium hydrosulphite is added to the resulting solution of the scarlet monoazo dyestuff to form 4-hydroxy-1-aminonaphthalene-8-carboxylic acid.

Title: Improvements in and relating to the guidance of ballistic missiles
Inventor: PARKER GUY MALCOLM
IPC: F41G7/36
Filed: 1958-05-13
Abstract: 944,910. Electric analogue calculating. ENGLISH ELECTRIC CO. Ltd. May 11, 1959 [May 13, 1958], No. 15369/58. Heading G4G. A ballistic missile guidance system comprises a device which contains or generates information defining a locus or path at least part of which has the form of a conic section, comparison of this information with information about the actual position of the missile causing the missile to be restored to the locus or path. Fig. 1 shows a path having straight beginning and end sections and a mid-section which is a circular arc, and Fig. 2 shows a computer for guidance in such a path. Integrating accelerometers I.D.M.L,I.D.M.M, I.D.M.N on a gyroscope stabilized platform provide pulses representing distance increments parallel to Cartesian axes Ol, Om, On respectively. I.D.M.N and counter NC keep the missile in the (1, m) plane. Pulses from I.D.M.L are counted in LC, which has an initial content l 0 . Consequently when the missile has moved a distance l 0  the output of LC changes sign from negative to positive and closes switch LS so that each subsequent pulse initiates one rotation of switch LR to transfer the content of counter LC to a common register CR; hence after a distance l 0  is travelled, the content of CR has the form 1. S1. Registering system RM operates like register RL, but switch MS is closed when the output of MC is negative and open when the output is positive, so no output is obtained from RM after the missile has moved a distance m 0  in the Om direction. While there is an output from each register, the content of CR has the form l.Sl + m. Sm and the missile is controlled by this content to move along an arc of a circle. The whole course of the missile is thus: an initial straight line along the O1 axis, of length l 0 ; a 90-degree circular arc of radium m 0  which is followed until a distance m 0  in the Om direction has been travelled; and a final straight line. If the pulses from I.D.M.L and I.D.M.M do not represent equal distance increments the mid-course will be elliptical, not circular. If switches LS and MS admit pulses from I.D.M.M and I.D.M.L respectively, the mid-course will be hyperbolic.

Abstract: 596,340. Counting-apparatus. TEDDINGTON CONTROLS, Ltd., HURST, W. F. F. MARTIN-, and BUSH, E. J. June 18, 1945, No. 15457. [Class 106 (i)] Electromagnetically-operated counting mechanism comprises a main solenoid energized in dependence upon the movements to be counted to operate a counter-actuating device, a latch for retaining this actuating device in operated position, a switch operated by the device to de-energize the main solenoid, and a second solenoid adapted to release the latch. The invention is described as applied to the registering mechanism of a liquid meter having a piston 47 reciprocating in a measuring cylinder 48. Contacts 49, 51 closed at one end of the stroke complete the circuit of the main solenoid 10 to pull to the left a link 12 to rock anti-clockwise against spring action a lever 13 carrying a pawl 15 which advances a ratchet wheel 17 driving trip and total counters, not shown. At the end of its stroke the lever 13 engages a pawl 22 to lock the ratchet wheel, the lever 13 being itself locked by a detent 27 urged by a spring into engagement with a step 16 on the lever. Movement of the detent 27 to locking position opens contacts 41, 42 to de-energize the main solenoid 10. A cam 33 connected to the lever 13 closes contacts 35, 36 in the circuit of an auxiliary solenoid 29, this circuit being completed and the solenoid 29 energized only when the piston 47 closes contacts 50, 52 at the other end of its stroke. The auxiliary solenoid 29 retracts a lever 28 to move the detent 27 to release the lever 13 which is therefrom returned clockwise by spring action. The counter is thus actuated only upon each complete to-and-fro stroke of the piston.
