Filed: 1965-05-21
Abstract: 1,150,571. Electronic skin resistance testing apparatus. G. BROOKE. 23 May, 1966 [21 May, 1965], No. 21592/65. Heading A5R. [Also in Division G1] An electronic skin resistance testing apparatus for measuring skin resistance and determining latency period (the time interval between the change of voltage occurring between two separate areas of skin after applying a stimulus to the subject) comprises an input circuit for connection to a pair of electrodes attachable to separate areas of the skin of the subject, an amplifier, an electrically reactive coupling between :the input circuit and the amplifier by which. only changes in voltage between the electrodes are passed to the amplifier, a timer, a starting switch to start the timer, means to actuate the starting switch at the instant the .subject receives a stimulus, and a trigger circuit connected to the amplifier output to produce a stop pulse for the timer in response to a pre-determined voltage change in the amplifier input circuit. A stimulus in the form of sound may be provided for by including an oscillatory circuit in the apparatus. Alternatively the apparatus may comprise a face mask, the stimulus being caused by a deep breath which also actuates the starting switch. The electrodes used are conveniently strips of fine wire gauze made of electrically conductive and chemically non-reactive metal, the ends of each strip of gauze being attached to the arms of a spring clip which is arranged to allow the band of gauze to be slipped over a finger of the subject, release of the clip causing the strip of gauze to be drawn around the skin of the finger. The apparatus suitably comprises a meter, a two-way switch having a neutral position and an on-off switch mechanically linked therewith, said switches being selfresetting, the placing of the switches in the first position causing the two-way switch to connect the meter to read the voltage of a battery in the apparatus while the on-off switch produces a voltage pulse to reset the timer, and the placing of the switches in the second position causing the two-way switch to condition the apparatus for operation. The apparatus may also comprise a potentiometer and meter for adjusting and indicating the sensitivity. The amplifier may be a multi-stage direct-coupled cascade amplifier. The specification describes a suitable circuit with reference to an accompanying drawing (not shown).

Patent GB-443686-A (GB)
Title: Process and apparatus for the continuous manufacture of sheets of undulated glass
IPC: C03B13/06
Filed: 1935-07-30
Abstract: 443,686. Glass manufacture. SOC. ANON. DES MANUFACTURES DES GLACES ET PRODUITS CHIMIQUES DE ST.-GOBAIN, CHAUNY, ET CIREY, 1<bis>, Place des Saussaies, Paris. July 30, 1935, No. 21645. Convention date, July 31, 1934. [Class 56] A process for the continuous production of corrugated sheets of glass consists in forming a flat sheet by a known method, and then drawing the sheet over a fixed shaping-device with a corrugated surface so that the plastic glass first assumes the shape of the surface and is then progressively cooled until it leaves the shaper in a rigid condition. The glass sheet may be reinforced with wire if desired. The continuous flat sheet of glass may be formed by flowing molten glass from a furnace 1, Fig. 1, into a rolling-machine 3, and the sheet 4 thus formed is drawn over the shaping- member 5 by means of conveyer rollers 7 and is carried into a leer 8. The shaper consists of a metal table having its upper surface formed with longitudinal corrugations or ribs 9 into which the plastic glass sags. The glass becomes sufficiently rigid before it leaves the shaper to resist deformation when it rests on the conveyer rollers 7. Counterplates 18, Fig. 5, or rollers may be arranged above the shaper to press the glass into the corrugations, and a depression 21<a> may be formed in the shaper below the counter plates to prevent wedging of the sheet if a thickening of the glass should occur. Wire netting may be fed into the molten glass, as it flows from the furnace to the rolling apparatus, when reinforced sheet is required. The shaper is hol'ow and may be made up of a number of sections. Water or other fluid may be circulated through the sections, or gas burners or electric heaters may be arranged to heat the sections to regulate the temperature of different parts of the shaper. In order to assist in cutting the glass into lengths, the upper roller of the rolling apparatus 3 may be provided with a projection 31, Fig. 1, to impress a groove on the glass sheet, or a separate roller may be employed which can be set in operation by a clutch. The glass may also be severed by heating it along a narrow transverse line either by means of a gas burner, or by means of an electric heater as shown in Fig. 14. In this construction, the glass sheet 32 is heated by two metal ribbons 33, 34 which are mounted in resilient supports 37, 38, respectively, of rubber or springs, insulating layers 35, 36 being interposed between the ribbons and the supports. The heaters are carried by rigid plates 39, 40 which are held apart by springs 43, 44 and are drawn together, when required to heat the glass, by electromagnets 41, 42. The device is mounted on rollers 60 so that it can travel with the sheet when the heating-ribbons are in contact with the glass. When the heater has released the sheet, the application of a cold tool to the heated line cracks the glass.

Title: A carrier frequency communication system with intermediate two-way repeaters, and a method for the remote supervision of these repeaters
IPC: H04B17/40
Filed: 1960-06-22
Abstract: 931,603. Supervising unattended repeaters. FELTEN & GUILLEAUME CARLSWERK A.G. June 22, 1960 [Aug. 3, 1959], No. 21826/60. Class 40 (4). In a carrier frequency communications system using unattended two-way repeaters each having a single amplifier connected between directional separating filters, supervision being accomplished from the terminal stations, a supervisory frequency lying in the gap between the two working frequency bands is doubled in a supervision unit which is connected to the output of the amplifier in a repeater and the output of said unit is applied to the filter which passes the upper working frequency band. In the sixty-channel system described the lower working frequency band ranges from 24 to 264 kc/s. (A to B) and the upper from 312 to 552 kc/s. (B to A) and the pilot frequency is 553 kc/s. From station A two basic frequencies f 1 , f 2  in the lower band are transmitted, f 2  being different for each repeater. Frequencies f 1 , f 2  form an intermodulation product in the amplifier AV of a repeater e.g. V2 and if this product corresponds to the supervision frequency of the repeater, it will be selected by supervision unit T, doubled in frequency therein and retransmitted to A via highpass filter HP 2 , AV and HP 1 . The level at which the doubled frequency is received gives an indication of the serviceability of the repeater. If the supervisory frequency fr extends over a narrow band within the band gap, the noise level around fr can be monitored when the carriers have been switched off. In an alternative form of supervision, the doubled intermodulation product interacts with the pilot frequency in their passage through amplifier AV to form a further intermodulation product which passes through low-pass filter TP 2  and is monitored at B. Either f 1  or f 2  or both may be transmitted from B in the upper frequency band, the formulation of modulation products and their subsequent detection being the same as described bove.

Title: Improvements in and relating to the manufacture of return bends for metal pipes
IPC: B21C37/28
Filed: 1923-09-03
Abstract: 204,036. Marine & Locomotive Superheaters, Ltd., (Assignees of Broido, B.). Sept. 15, 1922, [Convention date]. Pipes.-Return bends for pipes are made by providing means integral with the pipe to support the portion which is to form the outside of the bend to counteract the tendency of the pipe to collapse during bending, and then bending the pipe. The bend may be formed at some point in a long pipe or in a short length which is connected to separate pipes. The pipe is first thickened at the region where the bend is to be made. This may be effected by upsetting the pipe in one or more steps, by drawing, or by welding metal thereto. A rib 3 is then formed by forging in dies or by welding. In one form, a pair of dies 4, 5, Figs. 10 and 10, are closed transversely of the pipe to form the rib, the excess metal 7 being squeezed through slots 6 and being subsequently sheared off. The operation may be performed in stages by the use of several sets of dies, and the pipe supported by an internal mandrel. In a modification the rib is formed by a pair of axially movable dies. The pipe is then preferably heated. This may be effected over the shaded area, Fig. 4, adjacent portions being cooled by a stream of water. The pipe is then placed with the rib against a stop 10, Fig. 7, and is bent by moving grooved clamps 8 secured thereto over a curved guide rail 9. The rail is preferably eccentric to the stop so as to impart a tension to the inside of the bend to prevent folding of the metal. A tool such as 11, Fig. 9, may be run into the bend to remove constrictions and shape the rounded portion of the bend.

Title: Phosphoric esters of dextran and salts thereof and process for their preparation
IPC: C08B37/02
Filed: 1956-07-18
Abstract: The invention comprises a phosphoric ester of dextran or a partially degraded dextran or a salt of such an ester, e.g. the sodium salt. The compounds are preferably derived from partially degraded dextrans and have a molecular weight between 5000 and 60,000.  The numerical ratio of phosphoric acid residues to monosaccharide residues is preferably from 1 : 1 to 3 : 1.  They are prepared by phosphorylating an anhydrous suspension of dextran or partially degraded dextran in pyridine with an excess of phosphorus oxychloride or with an excess of phosphorus pentoxide and phosphoric acid at from - 22 DEG  C. to 0 DEG  C.  In one preferred procedure, POCl3 is added slowly to the suspension in the cold and the mixture is then heated, e.g. at 38 DEG C., with agitation.  In another preferred procedure phosphoric acid is added slowly to a mixture of the suspension with P2O5 in the cold and then heated, e.g. at 40 DEG  C., with agitation.  The sodium salt may be prepared by cooling the reaction mixture to about - 40 DEG  C. and neutralizing with sodium hydroxide at - 15 DEG  C. to - 5 DEG C., and may be precipitated with ethanol.  The dextran or partially degraded dextran is preferably subjected to a preliminary purification with alcohol and acetone and an activating treatment with pyridine, or to a preliminary treatment with liquid ammonia and metallic potassium at low temperature followed by drying.  The products have antilipaemic activity (see Group VI).  Examples are given of the pretreatment of dextran by both of the above procedures and of phosphorylation by both of the above procedures, and also of the fractional degradation of dextran with HCl followed by phosphorylation of the fractions.ALSO:Non-toxic, non-anticoagulant antilipaemic compositions for injection comprise a salt, e.g. a sodium salt, of a phosphate ester of dextran or a partially degraded dextran (see Group IV (b)) in a suitable carrier which may be inert, e.g. water, or may comprise other pharmacologically active material. The effects of intravenous and intramuscular injection of such a composition on the plasma turbidity of a dog previously fed a fat meal are illustrated.
