Title: Improvements in or relating to breathing apparatus
IPC: B63C11/22
Filed: 1961-02-15
Abstract: 913,950. Respiratory apparatus. SVENSKA A.B. GASACCUMULATOR. Feb. 15, 1961 [Feb. 18, 1960], No. 5606/61. Class 81 (2). Breathing apparatus for use under water or in noxious atmospheres comprises a membraneoperated inhalation valve 5, the valve and the membrane 9 being associated with separate chambers 15, 16 which communicate with a mask or mouthpiece 1 so that air entering the mask or mouthpiece from the inhalation valve has an injector effect, causing a sub-pressure in air in the membrane chamber 16, a direct connection 17 between the chambers being provided to counteract the injector effect. The chambers 15, 16 are separated by a partition 14, an aperture 17 in the partition permitting air to pass into the membrane chamber from the inhalation valve. The injector effect on air in the membrane chamber by air supplied to the mouthpiece 1 from the inhalation valve chamber 15 is counteracted by the passage of gas through the aperture so that the sub-pressure acting on the membrane to keep the inhalation valve open during inhalation is maintained substantially constant independent of the rate at which gas passes to the mouthpiece. The membrane is exposed to the ambient atmosphere or water on one side and carries an exhalation valve 12. The valve stem 7 of the inhalation valve is. spring loaded in the direction of opening to counteract the closing pressure exerted by gas flairing towards the inhalation valve.

Title: Improvements in and relating to cocoa butter compositions for use as a toilet article
IPC: C11D9/00
Filed: 1921-02-18
Abstract: A composition that will not melt in hot water and is used as a toilet article and particularly as a core for sticks of shaving soap, consists of cocoa butter and shaving-soap.  Beeswax may be added to raise the melting-point of the butter, zinc oxide to serve as a disinfectant, and oil yellow to colour the mixture.  It is prepared by melting 280 lb. of cocoa butter and 80 lb. of beeswax in a steam-jacketed kettle, dissolving therein 1 3/4 oz. of oil yellow, and stirring in 80 lb. of shaving-soap and 20 lb. of zinc oxide until a smooth paste is obtained.  Cores are prepared by cooling the paste to 60-75 DEG  F. and putting it through a plodder.

Title: Improvements in or relating to safe-guarding arrangements for electric communicationsystems
IPC: H04B3/10
Filed: 1955-02-25
Abstract: 764,175. Automatic volume control. STANDARD TELEPHONES & CABLES, Ltd. Feb. 25, 1955, No. 5695/55. Class 40 (4). In a transmission system in which the gain of amplifiers is controlled by a pilot current, an excessive signal level resulting from pilot failure at an amplifier is prevented by an arrangement which inserts a given amount of attenuation in cascade with the amplifier when the gain exceeds a specified value. The gain of the amplifier 2 is supervised by a relay 26 in which a signal from a test oscillator 17 after amplification in the amplifier 2 is compared with the unamplified test signal. The pilot current is selected by a filter 12 and controls a thermistor in a feedback path through a control oscillator 16 in known manner. The rectified pilot from the output of detector 15 is also applied to a marginal relay 30 which closes " high " or " low " contacts in response to a predetermined deviation (2 dbs.) of the pilot current which is less than the change of gain (6 dbs.) necessary to close the " high " contacts 27, 28 of relay 26. A relay 46 is jointly controlled by relays 26 and 30 to load the output circuit when the amplifier gain is high and the pilot current level is abnormal, by biasing a rectifier 41 in circuit with an additional winding 38 on the amplifier output transformer 34. A thermistor may be included in the loading circuit to reduce the rate at which the additional attenuation is introduced in order to prevent hunting in other parts of the system and alarm circuits may be connected to further contacts on relays 26 and 30. Examples of pilot and test frequencies are given.

When, from any such cause, a knife strikes the lever m, a rod o operates, through a bell-crank lever, the belt-shifting rod q, thereby stopping the machine. The eccentrics and the fixed bearings of the machine are fitted with antifriction balls or rollers.

Title: Phase slope delay network
IPC: H03H11/26
Filed: 1965-02-12
Abstract: 1,023,960. Phase delay network. STANDARD TELEPHONES & CABLES Ltd. Feb. 12, 1965 [Feb. 13, 1964], No. 6172/65. Heading H3U. A circuit for delaying an incident signal comprises means for slicing the frequency spectrum of the signal into a plurality of bands; means coupled to said slicing means for adding a phase shift to each band proportional to the centre frequency thereof; and means coupled to said adding means for combining the phase shifted bands and producing a delayed replica of the signal. Fig. 3a shows an LCR iterative network to produce four band slicing having cross-over frequencies F 1 , F 2 , F 3 , Fig. 3b. In this network L 11 C 12 > L 1 C 2 >L 21 C 21  and e 11 +e 12 +e 21 +e 22 =e in  at all frequencies. In Fig. 5 the incident signal to be delayed is applied to an all-pass filter bank 51 composed as in Fig. 3a but extended by iteration. The output of each filter, e.g. the filter having a centre frequency Fr, is fed to an R-C phase shifter network 52r having two outputs separated in phase leg 90 degrees, the two outputs corresponding to the sine and cosine of the frequency Fr and being fed tobalanced modulators 53r, 54r. The other inputs of the modulators are D.C. voltages proportional to the sine and cosine of a variable phase angle α; this angle a when plotted against the frequency to which it is applied must give a substantially linear function, the slope of which is dependent upon the desired delay. The sine and cosine D.C. voltages are obtained from balanced modulators 56r, 57r whose inputs are the voltage from the voltage controlled oscillator 58 and a voltage from a tap on the delay line 59 fed by the same V.C.O. Since the delay line has a tap corresponding to each set of associated balanced modulators and each tap along the line introduces greater delay the application of the resultant modulator outputs to the filter derived frequencies fed to the other group of modulators, e.g. 53r, 54r, produces the linear function sought. Thus, the output of the first tap on the delay line 59 produces the D.C. sine and cosine voltages for the lowest signal frequency band, the second tap the sine and cosine voltages for the second lowest band, and so on. The variation in the slope of phase vs. frequency, and hence the overall delay is produced by varying the control voltage of VCO 58. The delayed signal is produced by a summing amplifier 55.

Coking processes.-Finely-divided fuel is continuously distilled and gasified by being passed in a column through a heating zone containing heated pipes, steam and air being admitted at the bottom of this zone, and distillation products and fuel gases being withdrawn at the top at different levels. Fuel from a hopper 34 is supplied to a retort 12 in which are tubes 18 opening into spaces 20 divided into compartments 20a - - 20h so that the heating gases from burners 24 are given a tortuous path to the outlet flue 72. Superposed sets of gas-withdrawal tubes 42 are provided, the upper one being used for removing air from the charge and the lowermost one for producer gas or water gas which may be mixed with the distillation gases, these tubes leading to a condenser 50. The hot residue falls into a water seal 52 from which the steam passes into tha charge to form water gas, air being supplied by pipes 90 for the generation of producer gas. The water seal has a number of conveyer shafts 54 with blades 56 which move the residue to another conveyer 58 discharging into a sump from which the ash &c. is discharged by an endless belt conveyer 62 into a pug mill 64 leading to an amalgamator 66 in which the ash constituents are separated in the manner described in Specifications 151,236, [Class 82 (ii), Washing granular &o.], and 159,497. The rate of heating the fuel is controlled by returning some of the relativelycool gases from the chambers 20h to the combustion chambers 3,0 by means of a return conduit 70 and pipes 75, and bye-pass dampers 80 are used for the same purpose. The tubes 18 and 42 may be covered with silicious material as described in Specification 292,535, [Class 99 (ii), Pipes, tubes, &c.]. Specifications 8187/05, 277,660, and 299,792 also are referred to.
