[Class 2 (iii)] Nuclear saturated or unsaturated ketones of the cyclopentanopolyhydrophenanthrene series are prepared from the corresponding aldehydes of this series by reaction with an aliphatic diazo compound. Parent materials include aldehydes derived from aetio-cholane, pregnane, oestrane, hydro-oestrane and their sterio-isomers. The parent aldehydes may contain a nuclear keto group. Diazo compounds mentioned include diazomethane and its di-, and monosubstitution products, such as mono- and di-alkyl-, cycloalkyl-, aralkyl-, and aryl-diazo compounds Examples specified include diazoethane, diazobutane, diazopropylene, phenyldiazomethane, diazo-mono-, and di-carboxylic acid derivatives such as diazoacetic acid esters, amides or nitriles, diazomalonic acid esters and diazosuccinic acid esters. In the latter cases saponification and decarboxylation may follow the reaction with the aldehyde group. The compound prepared according to this invention possess the general formula where R is a residue containing the cyclopentanopolyhydrophenanthrene nucleus, R1 and R2 represent hydrogen or radicals containing carbon such as substituted or unsubstituted hydrocarbon residues or substituted carboxyl groups. The ketones are isolated and purified by means of the usual ketone reagents. In examples : (1) An ethereal solution of the trityl ether of #<5>.<6>-3-oxyaetiocholene-17-aldehyde is treated with diazomethane and after standing some days warmed with alcoholic hydrochloric acid to give A <5>.<6>-pregnenol-3-one-20 which is purified by reaction with the chloride of trimethylaminoacetic acid hydrazide. (2) An ethereal solution of #<4>.<5>-3-keto-aetio-cholene- 17-aldehyde is treated with diazomethane to give #<4>.<5>-pregnene-dione. A sample has been furnished under Sect. 2 (5) prepared in accordance with the following schedule : an ethereal solution of A <5>.<6>-3- acetoxy-aetiocholene-17-aldehyde is treated with an ethereal solution of diazoacetic ester, and then refluxed with methyl alcoholic potassium hydroxide. After acidification with dilute sulphuric acid and extraction with ether there is obtained #<5>.<6>-pregnenol-3-one-20.

Patent GB-597435-A (GB)
Title: Printed fabrics and methods of producing same
IPC: D06Q1/08
Filed: 1945-08-17
Abstract: Fabrics are printed to form a glazed design which may be coloured or not by employing a printing paste containing melamine formaldehyde resin, or homologues thereof.  The resin is the condensation product formed by combining 1-5 molecular parts of aqueous formaldehyde with 1 part of melamine in alkaline solution.  The resin is made into a paste by mixing 75 parts by weight of cornstalk paste, formed by cooking .75 lbs. of cornstalk in one gallon of water, with 15 parts by weight of melamine formaldehyde and 10 parts by weight of a 10 per cent solution of ammonium chloride.  A plasticiser such as di-butyl phthalate may be added.  A gum tragacanth paste or a protein thickener may be employed.  After printing, the fabric is dried at a temperature insufficient to polymerize the resin, and is polished by means of heated calendering rolls.  The fabric is then subject to a heat treatment to complete any polymerization of the resin caused by the drying process, a treatment at between 290-300 DEG  F. for five minutes may be used.  The fabric is finished by a washing process which removes the glaze except at the printed portions which thus appear on the fabric as a glazed coloured or plain design, which may resemble a figured weave.

Title: Detecting the arrival of material at a point in rolling mills
IPC: H03K17/95
Filed: 1960-06-15
Abstract: 932,586. Locating conductive bodies. SOUTH AFRICA IRON & STEEL INDUSTRIAL CORPORATION Ltd. June 15, 1960 [June 15, 1959], No. 21090/60. Class 37. [Also in Group XXII] A method of detecting the arrival of a rod or other material at a point in a rolling mill comprises forming a closed electrical loop, including the rod and a component of the mill at the time of arrival of the rod, and detecting the change in electromagnetic induction caused by the current in the loop. Fig. 1 shows a rolling mill comprising two stands a, c driven by a motor M. When the rod 1, travelling from left to right reaches rollers 2 a closed electrical loop is formed by part of the rod 1, rollers 2, gear-boxes 4, 5, 4<SP>1</SP> and rollers 21. The noise voltage induced into winding 7 of the toroidal core 6 increases when the loop is closed. The noise voltage is fed to an amplifier (Fig. 4, not shown), tuned by a parallel T circuit to 1 kc/s., then rectified and differentiated before being fed to pin 2 of a bi-stable circuit 12 (Fig. 5), energizing relay A. The signal is now delayed by the circuit shown in Fig. 5 until the rod 1 has travelled sufficiently far so that the distorted head 9 can be cut-off by the shear 10. The delay is achieved by the use of a voltage Vin proportional to the speed of the mill derived from a tacho generator, the voltage being integrated by capacitor C, starting from the time when the contact of relay A opens. A voltage proportional to speed is added to the integrated voltage by variable resistor Rk to allow for the operating time of the shear 10. When the combined voltage reaches the preset voltage Vk the two halves of valve V4 change over, feeding a negative pulse to pin 7 of valve 12, releasing relay A so that contacts A transmit an earth along line 7<SP>1</SP> to initiate the pneumatic actuator 8 which operates the shear 10. The invention may alternatively be used for the control of collapsible guides between mill stands permitting the formation of a free loop or for the operation of an automatic scrap alarm and cutting in the event of cobble. Detecting head construction.-Fig. 2 shows a core 6 toroidally wound with wire 7 insulated by ceramic beads, encased in asbestos 8 and having a partly enclosed steel sheath 9. The sheath 9 is provided with four lugs so that the detector may be mounted on the exit guide of one of the mill stands. Modifications.-In applications where the noise voltage induced in the loop is insufficient, a voltage may be induced by a further toroid 6. Alternatively, a voltage may be fed to winding 7, the change in impedance being detected by an oscillator when the loop is opened or closed.

Abstract: 1394432 Input-output systems PLESSEY CO Ltd 16 June 1972 [24 June 1971] 21221/73 Divided out of 1394431 Heading G4A [Also in Division H4] Duplicated multi-stage switching networks α, # have cascaded stages DS, PS each of which scans a plurality of input ports and, on detection of a demand condition on an input port, passes the demand on towards a message handling device PA acting as a buffer between a data processing system CPS and the switching network. Each stage DS, PS, over which the demand is extended, appends an input port identification field to the address information of a message received from a peripheral device SCP initiating the demand each peripheral device being connected to at least one input port in each network α, #. For transmission in the opposite direction, reception of a demand by a switching stage causes it to stop scanning its input ports and to use an address field of a message to select one of the input ports for onward transmission of the remainder of the message. Each transmission path includes control, data and timing wires for each direction. In the arrangement shown, serial-paralle adapters PA have access units similar to those provided in the memory modules and peripheral units of the system described in Specification 1,394,431 and include command and status registers together with data-in and dataout register stacks to form an interface between that system and low activity peripheral devices SCP. Other features of the switching stage include (1) a register which is cycled in synchronism with the scanning of the input ports and which stores bits for controlling the acceptance of demands on the input ports, write access to the register being obtained via the input ports, (2) a pair of input port address counters whose states are compared to prevent any single fault causing an input port to be skipped. Each peripheral device has an associated access unit which includes an address recognition circuit and addressable control, status and data registers as in the peripheral access units described in the parent Specification 1,394,431.
