Title: Improvements in and relating to portable pumps for inflating pneumatic tyres and the like
IPC: F04B33/00
Filed: 1921-11-28
Abstract: 191,907. Cooper, J. F., and Industrial Rubber Products Ltd. Nov. 28, 1921. Oscillatiiig-cylinder pumps; actuating by foot power. - Portable foot pumps, of the kind in which the pump barrel and the operating pedal are pivoted respectively to the opposite ends of a base plate, and the pedal is connected between its ends to the piston rod, are arranged so that the area of the piston can he varied to suit the pressure at different stages of the compression. The pump comprises a piston 10 connected at 27 to a treadle 28, and a further annular piston 16 carried by a tube 13 which can be fixed to the pump barrel 1 so that the piston 10 is used alone, or can be fixed to the piston 10 so that the two pistons work in conjunction. In use, the two pistons are used until the delivery pressure reaches a suitable amount, and then the smaller piston is used alone to complete the operation. The tube 13 carries a block 17 and a pin on which slides a spring-influenced slotted plate 20. By rotating the tube 13, and then depressing a cam 18, the slotted plate can be engaged with lugs on the member 24 to fix the two pistons together, with lugs on the barrel to fix the tube to the barrel, or with one lug on the barrel and one on the member 24. to lock all the parts for storage. Delivery is effected through a ball-valve 5 into a two-armed passage, one branch leading to a pressure gauge 4 and the other 'branch 7 to the flexible delivery pipe.

Abstract: 849,312. Electric telegraphy. DE STAAT DER NEDERLANDEN, TEN DEZE VERTEGEN-WOORDIGD DOOR DE DIRECTEUR-GENERAAL DER POSTERIJEN, TELEGRAFIE EN TELEFONIE. Oct. 11, 1957 [Oct. 16, 1956], No. 31828/57. Class 40(3). [Also in Groups XL(c)]  In a circuit for detecting a signal in which a prescribed polarity persists for a period greater than a predetermined time interval, such as the circuit arrangements described in Specification 680,103, the valve or cold cathode discharge tube normally employed is replaced by a transistor which controls an output or supervisory relay. The transistor may be of the PNP or NPN type, and a pair of transistors may be used in push-pull. In the arrangement shown in Fig. 1 employed to provide a response to the reception by a relay R of a telegraph signal having five code elements similar to the start element, i.e. - signal No. 32 of the International Teleprinter Alphabet - the armature r against the contact s in response to the stop element polarity rapidly charges a capacitor C to a positive potential via rectifier Dl. On movement of the armature r to the contact m, the capacitor C slowly discharges through resistor Rl so that after a period equal to that of six elements of the start polarity the voltage at L drops to a point such that the transistor PNP conducts and relay A in its collector circuit is operated to close contact a of the circuit T2, T3. When the emitter current begins to flow, the potential at points L, M rises to provide a positive feed-back compensating the negative feed-back caused by the output impedance at the emitter supplied at point M by the potentiometer. In an alternative arrangement, Fig. 3 (not shown), the discharge circuit of the capacitor C is connected to earth, and Fig. 4 (not shown) comprises two transistors in push-pull connected to operating and biasing windings of the relay A. Fig. 5 (not shown) is modified to incorporate an NPN transistor, with a further modification in Fig. 6 (not shown) having an earth connection for the discharge (timing) circuit of the capacitor C. The circuit may be employed in telegraph exchange systems to detect a clearing condition represented by a prolonged signal of one polarity. Reference has been directed by the Comptroller to Specification 792,625.

Abstract: 1,220,761. Treatment of spent pickle liquors. CHEMICAL SEPARATIONS CORP. 25 June, 1969, No. 32099/69. Heading C1A. [Also in Division B1] In a process for pickling metal, the spent pickle liquor is continuously regenerated by (1) continuously withdrawing spent pickle liquor from a pickling process, (2) passing said liquor through a first section of an ion-exchange column loop having a movable ion exchange resin bed, whereby metal ions in the spent liquor are exchanged for hydrogen ions in the exchange resin (thus regenerating the pickle acid) whilst (3) simultaneously treating a second portion of said ion exchange resin loaded with metal ions from (2) with a regenerating agent in second section of said column loop; (4) substantially simultaneously stopping the flow of spent pickle liquor, and said regenerating agent; (5) moving the ion exchange resin bed from one section of the loop to another contiguous section therein, thereby replacing at least a part of said resin in said first section with regenerated resin from step (3) and moving a further part of used resin from step (2) to said second section for regeneration; (6) withdrawing from said second section a solution of the metal salt of the ion exchange regenerating agent, and obtaining the regenerating agent therefrom; (7) continuously recycling the regenerated regenerating agent to said second section of said column loop. The movement of the ion exchange bed and solutions in the column loop is controlled by conductivity probes which detect solution interfaces. The solution of the metal salt of the ion exchange regenerating agent is either (a) hydrolysed at elevated temperature and pressure to produce regenerated regenerating agent and the metal oxide, e.g. iron, by hydrolysis in the presence of an O 2  containing gas such as air or (b) treated in a fluidized bed reactor to produce the metal oxide and vapours which are scrubbed with water to produce the regenerating agent. The regenerating agent specified is nitric acid and resins specified are "Dowex", a sulphonated polystyrene resin, "Amberlite" and "Permutit" (Registered Trade Marks). Pickle acids specified are sulphuric, phosphoric, hydrochloric and citric, the pickle solution being controlled to contain acid of 5-20% strength and metal salt at a concentration of 1-10%. Apparatus is described (see Division B1, ion exchange).

Abstract: 1,162,033. Measuring temperature. BRITISH OXYGEN CO. Ltd. June 20, 1968 [July 12, 1967] No. 32121/67. Heading G1D. Apparatus for measuring the degree of undercooling or super-heating of a liquid, particularly a liquefied gas, in a container 20 comprises a differential pressure gauge 11 coupled on the one hand to a vapour pressure thermometer consisting of a sealed bulb 14 preferably containing the same gas as that of the container 20 and connected to the gauge 11 by a line 12 and on the other hand to a conduit 13 leading to the interior of the container 20, and responsive to the pressure therein. The differential pressure measured by the gauge, i. e. the difference in pressure between the container 20 and that of the bulb 14, which is directly responsive to the temperature in the container will give a direct measure of the temperature of the liquid in relation to its boiling point. The liquefied gas may be nitrogen, oxygen or argon and a vaporizing coil 21 is included in the conduit 13 to ensure that the gas therein is in the gaseous state. This coil may be dispensed with if a conduit such as 15 is employed, but in this case allowance must be made for the difference in height between the conduit and the bulb 14 in the container 20.
