Title: Improvements in or relating to apparatus for the administration of inhalent gas mixtures
IPC: A61M16/10
Filed: 1946-11-06
Abstract: 623,059. Respiratory appliances. MARRETT, H. R. Nov. 6, 1946, Nos. 32964/46 and 14665/47. [Class 81(ii)] Apparatus for the administration of inhalent gas mixture comprises a unitary head in the form of a casing to which are attached a number of flow meters for the supply of basal gases, vaporizers containing volatile liquids such as ether and trichloroethylene or chloroform and a unit such as a soda-lime container for the absorption of carbon dioxide, the casing having also non-return inlet and outlet valves for connection to the expiratory and inspiratory tubes attached to the face mask, a connection for the re-breathing bag and valves for controlling the flow and admixture of gases in the patient's and the basal gas circuits. The apparatus comprises a single head casing 21 within which are housed cylinders 30, 31, 32 having rotary drum valves 10, 11, 12, the drums being ported and divided into chambers. The soda-lime container 5. the ether reservoir 7 and the tricholorethylene container 9 are connected to the casing 21 directly below the drums 10, 11, 12 respectively and are controlled thereby. Figs. 3 and 5 show an embodiment, while Fig. 1 illustrates diagrammatically the circuits of the patient and of the basal gases. In operation, expiratory gases from the face mask pass through conduit 4, past the non-return valve 2, through conduit 13 to the drum 10, thence through the soda-lime container 5 to the re-breathing bag 6 through conduit 14. With the valves in the positions shown in Fig. 1, the return of the patient's gases from the re-breathing bag 6 to the inspiratory conduit 3 pass through the sodalime container 5, along conduit 15 through tubes 17a, 18 in the ether container 7 and past the non-return valve 1. The basal gases from the flow meters 23 pass through conduit 8 through drum 12, conduit 19, valve 11c and through the ether container 7 to join the inspiration of the patient's gases. If it is desired to pass the basal gases through the trichloroethylene container 9 the soda-lime container must be short circuited in view of the reaction of the soda-lime on the gas vapour and to ensure this the drums 10, 12 controlling the respective containers are adapted to be interlocked by some such means as a spring plunger so that the drum controlling one container is in the "off" position when the drum controlling the other is in the " on " position. The appropriate drums may be so set that the gases in the patient's circuit may in part pass through the ether container and in part by-pass it. Similarly, the basal gases may in part pass through either or both of the ether and trichloroethylene chambers and in part by-pass one or both containers.

Abstract: An L-amide compound of the formula <FORM:1102300/C2/1> wherein each of R1 and R2 is a hydroxy or methoxy radical, is obtained by forming a supersaturated solution of the DL form of the amide compound in a solvent comprising a C1-C8 alkanol, or a mixture thereof, an aqueous C1-C8 alkanol or a mixture thereof, acetonitrile, a C3-C8 alkyl ketone, dioxan, formamide or water in which at least 1 gram of racemate dissolves per litre of solvent, contacting the DL supersaturated solution with at least 1% by weight, based on the weight of amide in solution, of its L-isomer in crystalline form; and separating the L-enantiomorph which crystallizes.  The mineral acid addition salt of the acid of the formula <FORM:1102300/C2/2> is obtained by hydrolysis of the amide of the above formula with a dilute mineral acid at elevated temperature.  The free acid may be obtained by reacting the addition salt with an alkylene oxide or an inorganic base. Alternatively, if R1 and/or R2 is methoxy, the hydrolysis step may be accompanied by dealkylation if concentrated mineral acid and a temperature of 50-180 DEG  C. is used.  Examples are given for the production of L a -amino-a -vanillyl propionamide, L a -amino-a -veratryl propionamide and L a -amino-a -methyl-b  -(3,4 - dihydroxyphenyl) - propionamide, for the preparation of the appropriate racemic starting materials, and for the amino acids corresponding to the amides.

Title: Digital source of periodic signals
IPC: H04L27/30
Filed: 1971-07-15
Abstract: 1354931 Substation apparatus SOC LANNIONNAISE D'ELECTRONIQUE and COMPAGNIE INDUSTRIELLE DES TELECOMMUNICATIONS CIT-ALCATEL 15 July 1971 [17 July 1970] 33359/71 Heading H4K A digital source of analogue signals comprises a store for a set of digital coefficients defining the shape of a portion of a waveform, and means to sample a selection of those coefficients repetitively, a digital to analogue converter for converting the selected coefficients into an analogue waveform and a filter through which this waveform passes. As described a cyclic address generator incremented in equal steps selects a number of addresses for each cycle. If the stored coefficients define the shape of a full cycle or period of a waveform these addresses are all addresses of coefficients. In the detailed embodiment for generating dual frequency tones coefficients defining the first quarter cycle of a sine wave are stored and two address generators each cycle during each cycle of the associated tone, the two most significant bits of each generated address being used in an address selector only to determine the polarity of the tone and whether the remainder of the address or the complement thereof should be used to address the store for each quarter cycle, the complete cycle being produced from its symmetrical relationship with the first cycle. As shown depression of a single key of a keyboard 18 applies potentials on two conductors to a selector 19, the conductors being associated with the row and column of the selected key, the keys being arranged in four rows and three columns. A store 6 stores in fixed point digital form seven increment values, one associated with each conductor and a corresponding tone. The two potentials gate in alternate time instants the corresponding increment values to an address generator including an adder 13 which repeatedly increments the counts in registers 11  and 12 using one increment value for each. The whole number part of the total returned to register 11 is also passed to an address selector 2 which as described above reads a coefficient from an address in a store 3 into a register 15 and adds to that register a polarity bit. In the next time instant the total returned to the register 12 is also used to access the store 3 (in connection with generation of the second frequency) and a coefficient together with a polarity bit supplied to an adder 17 which adds these to the values in register 15. The sum is converted to analogue form at 4 and passed through a filter 20. Thus the contents of registers 11 and 12 are associated one with each of two tones and access the store alternately to read out coefficients of the corresponding simultaneous tones.

In Fig. 2, on the right, a strip spring 18 has a holding-down arm 18a, V-shaped part 18b and a locking tag 18c accommodated in a rectangular opening 19 of lug 17a. The lug 17a may be provided at the outer end of bridge part 14a, in which case the spring is reversed. Preferably lateral bent parts of spring 18 embrace the side edges of lug 17a. On the left of Fig. 2, arm 18a is extended by the attachment of a further spring part 28 which serves as a cover for the caliper opening 16. On the left of Fig. 5 a single holding spring 28 has near each end a slot 28a which fits over one of the lugs 17, 17a. The spring 28 is held in place by the introduction thereafter into each opening 19 of an element 29 having two bends 29a to locate it relative to the lug. Lateral lugs 30 may be provided on spring 28 which extend downwards and make resilient contact with the brake pads, pressing them outwards. Thereby the conventional cross-spring 31 may be dispensed with. With the construction of Fig. 2 (right) and its variant above referred to, the brake pads may be removed for replacement without releasing the caliper from the brake holder.

Inventor: MOORE ALAN
IPC: C22C25/00
Filed: 1961-09-19
Abstract: Beryllium alloys containing one of Mn, Cr or Ti are heated so that the alloying element migrates to the grain boundaries and forms a compound with the beryllium thereat.  The maximum value for the alloying element is stated to be 0.2% by weight.  The heating temperature is between 500 and 1025  DEG C. and varies with the content of alloying element, the time for heating being related directly to the temperature used.  In an example billets are cast cooled from 1285  DEG C. to 1000  DEG C. in 10 minutes and from 1000 DEG C. to 20  DEG C. in 3 hours and are then sealed into welded steel cans.  The cans are preheated at 1050  DEG C. for 10-45 minutes, extruded and allowed to cool to 700  DEG C. in 1/2 minute and to 20 DEG C. in 45 minutes.  This as extruded material is then "averaged" at 500-1025  DEG C. as above.

Title: Improvements in or relating to circuit arrangements for switching energising current to electromagnets
Inventor: NORMAN HERBERT JOHN
IPC: H03K17/08
Filed: 1964-08-17
Abstract: 1,115,382. Transistor switching circuits. WILLIAM HILL & SON, and NORMAN & BEARD Ltd. 10 Aug., 1965 [17 Aug., 1964], No. 33503/64. Heading H3T. [Also in Division G5] In a switching circuit which energizes an electromagnet 11 connected in series with the emitter of a transistor 1 having its collector 2 connected direct to a source of potential and its base arranged for control by a mechanical electric switch 5 connected to the base or to one end 6 of a resistor R 1  the other end of which is connected to the base, an additional resistor R 2  limiting emitter-base reverse voltage is connected between the emitter and the base or the one end 6 of the resistor R 1 . As shown the transistor 1 is biased OFF by the potential applied from 8 via resistor R 3 . When the key contact 5 and stop or coupler switches 10 are closed the transistor conducts and the action electromagnets 11 of a pipe organ are energized. The transistor is protected against any positive surge which may occur at the emitter when the action magnets are de-energized by the resistor R 3  and the supply 8 since if the potential at the emitter rises beyond the potential at 8 the transistor conducts causing a slightly delayed switch-off action. The resistor R 2  limits the emitter-base reverse voltage if a negative test potential is applied to the bus-bar 4 or to the action magnets and resistor R 1  prevents excessive base current.
