Patent GB-254778-A (GB)
Title: Improvements in or relating to machines for forming sand and similar moulds
IPC: B22C13/10
Filed: 1925-04-01
Abstract: 254,778. Howard, Ltd., J. &. F., and Shorten, J. G. April 1, 1925. Moulding-machines especially intended for making moulds as described in Specification 254,777 have a ram or rams D secured to a hand lever E by connecting-members so as to be well in advance of the lever, thus enabling the rams to enter the flask. The lever is pressed down one or more times by hand or power to pack the sand and is pivoted to an upright B<2> of a table A on which the pattern C rests. The lever is counterbalanced by a weight E<6> and may be held horizontal by a removable pin B<4> or in its raised position by a spring catch E<4>. The sand may be supplied by a hopper, valve and flexible pipe. If desired, the rammers may be connected to the levers by adjusting-screws. An opening B<5> is formed in the table to discharge surplus sand. Patterns.-Prior to filling the flask with sand a metal chilling piece G may be placed on the pattern block. This piece is securely held in position when the sand is rammed and enables the point of a plough-share to be chilled on both sides.

Title: Improvements in apparatus for, and methods of, measuring volume
IPC: G01F23/288
Filed: 1965-03-02
Abstract: 1,087,424. Electro-physical and radiation measurement. SIMMONDS PRECISION PRODUCTS Inc. March 2, 1965 [Oct. 28, 1964], No. 8765/65. Headings G1A and G1N. The volume of a tank (or the ullage space in a liquid fuel tank) is measured by injecting a known mass of gas and measuring its density. The trace gas may be ionized by secondary radiation, or carry radioactive isotopes such as iodine 131 or iridium 192 in oil or water vapour, or finely divided solids (gold 198) in suspension, under zero gravity conditions, and the detector may be an Ohmart cell type. Alternatively a magnetic gas analyzer can be used with paramagnetic oxygen as the trace gas. The fuel may be housed in a bladder in the tank, so that the ullage space remains fixed regardless of the attitude of the tank.

Abstract: 1,264,050. Steroidal lactones. AMERICAN HOME PRODUCTS CORP. 24 Feb., 1970 [24 Feb., 1969], No. 8942/70. Heading C2U. Novel steroids of the partial Formula (I) (wherein Q represents the remaining A, B and C rings of a steroid nucleus of the androstane or estrane series) are prepared by NaBH 4  reduction of steroids of the partial formula (wherein R<SP>1</SP> is H or C 2-4  acyl), prepared in turn by treatment of steroids of the partial formula with an organic peracid in the presence of a nucleophilic reagent to give products wherein OR<SP>1</SP> is hydroxy, with, when required, subsequent acylation to give products wherein OR<SP>1</SP> is acyloxy. Products containing a 3-hydroxy group may be acylated by standard procedures. Preferred products have the formulµ (where R is H, C 1-4  alkyl, C 5-6  cycloalkyl or C 2-4  acyl), and novel intermediates are those corresponding to the 7α,8α-epoxides and containing an OR<SP>1</SP> group in the lactone ring. These intermediates may be prepared from 17#- hydroxy - 17α - (3<SP>1</SP> - furyl) starting materials already containing the 7α,8α-epoxy group or from corresponding materials containing a #<SP>7</SP> double bond.  Equilin 3 - methyl, - ethyl, - propyl, - isopropyl, - n - butyl, - sec. - butyl, - cyclopentyl and -cyclohexyl ethers are prepared from the sodium or potassium salt of equilin and the appropriate alkyl or cycloalkyl halides. These and the corresponding tetrahydropyranyl ether are converted to the corresponding 7α,8α- epoxy compounds by treatment with m-chloroperbenzoic acid. Starting materials of the partial Formula (V) are prepared from the corresponding 17-ones, 3-iodofuran and n-butyl-lithium; hydrolysis of the 3-tetrahydropyranyl ether of 7α,8α-epoxy- 17α - (3<SP>1</SP> - furyl) - 3 - hydroxyestra - 1,3,5(10)- trien-17-ol gives the free 3-ol, which on acylation is converted to 3-acylates e.g. the acetate, propionate and butyrate. The novel steroidal lactones of the partial Formula (I) possess estrogenic activity, and they may be made up into pharmaceutical compositions with suitable carriers.

Title: Improvements in or relating to electrical logic circuits
Inventor: COATES HAROLD NOEL
IPC: H03K19/10
Filed: 1961-03-15
Abstract: 983,865. Tunnel diode frequency dividing circuits; telegraphy. INTERNATIONAL COMPUTORS & TABULATORS Ltd. Feb. 14, 1962 [March 15, 1961], No. 9463/61. Headings H3T and H4P. A parametric logic circuit comprises a series pair of negative resistance devices 3, 4 connected in parallel with a series pair of reactors 5, 6 and a reactor 9 of opposite sign connected as shown. The circuit is " pumped " at twice its resonant frequency and gives a sine wave output at terminal 12 which may have either of two phases relatively displaced by 180 degrees depending on the nature of an input signal. As shown, tunnel diodes 3, 4 are normally biased into conduction by a D.C. source 20. The reactance of diodes 3, 4 and of capacitor 7 is low at the operating frequency hence the circuit is equivalent to a parallel tuned circuit formed by the parallel combination of inductors 5, 6 with capacitor 9 and resonant at half the frequency of the 250 mc/s. generator 1. Alternatively, the inductors 5, 6 may be replaced by capacitors and capacitor 9 by an inductor. One of the tunnel diodes 3, 4 changes its operating point from one positive resistance value to the other during the first positive half cycle of the pumping frequency from generator 1. This results in shock excitation of the resonant circuit 5, 6, 9 at half the pumping frequency. The other diode changes it operating point during the next positive half cycle of pumping wave and so on. The phase of the output may be changed by biasing the circuit to one of two levels of direct voltage from source 21. The 250 mc/s. generator 1 should preferably be modulated by a sine or square wave so as to quench the oscillation in the resonant circuit and hence facilitate change of phase by source 21. Alternatively, the phase of output may be controlled in accordance with the phase of a sine wave at half pumping frequency fed to terminal 13. Majority logic and multi-stable state operation. -The output windings 10a, 10b, 11a, 11b of a number of such circuits may be connected in series. The phase of the signal at terminal 13 is dependent on the phase of the majority of these circuits and governs the phase of the output from terminal 12. Multi-stable circuits may be made by the use of more than two tunnel diodes in series.
