Title: Improvements in or relating to ceramic compositions for high power capacitors
Filed: 1957-02-22
Abstract: A ceramic dielectric composition comprises magnesium titanate, 4-5 per cent. lanthanum oxide, 9-21 per cent. strontium titanate, and 4-5 per cent. clay, the percentages being by weight of magnesium titanate.  In the examples the magnesium and strontium titanates are first prepared by sintering the appropriate oxide with titanium dioxide at about 1260 DEG C. and grinding to pass 200 mesh after which the products are ground in water with lanthanum oxide and clay, dried, ground again, and passed through a 200 mesh sieve.  The powder is converted into a paste by an organic binder such as a solution of rubber in trichlorethylene, dextrine, or starch, and is then shaped and fired at 1300-1400 DEG C., e.g. 1360 DEG C. Preferred percentages of strontium titanate, according to whether a positive, zero or negative temperature coefficient of permittivity is desired, are 9-11, 15-17, 19-21 respectively.

Filed: 1963-02-15
Abstract: 1,005,343. Wave guide switches. ALBISWERK ZURICH A.G. Feb. 15, 1963 [Feb. 16, 1962], No. 6153/63. Heading H1W. [Also in Division H4] A single antenna is coupled to both a transmitter and a receiver via impedance transforming networks which contain semi-conductor diodes acting to give the desired high or low impedance. In Fig. 1 the lines A, S, E lead to the antenna, transmitter and receiver respectively. The impedance transforming network across the transmitter comprises lines 9, 10, which are of a length (2n+ 1)#/4 equal to an odd number of quarter wavelengths of the transmitting frequency connected at their ends by diodes 11, 12 inanti-parallel. The line 8 between this network and line A is also of length (2n+ 1)#/4, similarly the network leading to the receiver comprises lines 2, 3 of length (2n+ 1)#/4 and diodes 5, 6. When the trans-   mitter S produces an R.F. pulse the diodes 5, 6, 11, 12 conduct in the appropriate half cycles presenting low resistance at the ends of the lines. This means that the input impedance of the branches are high and little energy is lost. On receipt of a pulse by the antenna the diodes are non-conductive because the lower energy of the received pulse is below their threshold voltage. The diodes therefore present high resistance at the end of the lines. The input impedance for lines 2, 3 is low while that for lines 8, 9, 10 is high and so the received energy passes to the receiver. Single diodes in each branch may be adequate in some cases. In order to receive higher signal energies the diodes may be back biased during reception and forward biased during transmission. An alternative embodiment is shown in Figs. 2A and 2B in which oscillatory circuits with zero impedance at the transmitter frequency are used. In the receiver line coupling (2A) the diodes 21 are so connected that they short circuit the input of the receiver for transmitted signals but open the input for reception. In the transmitter line coupling (2B), however, the diodes 25 and 28 provide a signal path during transmission but break the path during reception.

Abstract: 525,649. Stapling. HAZEWINKEL, R. C. Feb..24, 1939, No. 6203. Convention date, Feb. 28, 1938. [Class 89 (iii)] In a stapling tool which is operable by one hand for bending staples to U-form from a flat strip and then driving them into the work, pressure upon a handle first moves a bending die and stresses a driving spring, and then releases the spring so that the latter imparts a driving stroke to the driver. The tool comprises a casing 1 for a roll of flat, strip-connected staples 36, a housing 2, and a plunger 10 formed with a handle 11 and raised by a spring 14. The bending die 15, which is adapted to bend the staple over an anvil 28, is fixed to the plunger 10 and makes frictional contact with the driver 17 which is slidable in the plunger. Also slidable in the plunger is a hammer 12 under pressure of a spring 13. When the plunger 10 is forced down, the die 15 bends a staple and a pawl 5 holds the hammer 12 from movement, so that the spring 13 is stressed. Ultimately, an edge 23 on the plunger releases the pawl, so that the hammer 12 is forced down against the driver. The staple strip is fed by a pawl 7 having lugs 34 which engage the staple legs after bending. The die 15 is thicker than the driver 17, so that three staples are bent at each descent of the die. The housing 2 has a removable cover 3.

Patent GB-1007655-A (GB)
Title: Process for the manufacture of organic sulphonylchlorides
Inventor: JONG JAN IDE DE
IPC: C07C309/78
Filed: 1963-02-18
Abstract: Organic sulphonylchlorides are made by treating organic sulphonic acids with chlorosulphonic acid in the presence of an inert solvent, in which the sulphonylchloride is soluble, but in which the organic sulphonic acid and sulphuric acid are insoluble, and which forms a second liquid phase, separating the phases after completion of the reaction, washing the solvent phase with water, distilling off the water as an azeotrope with the solvent to remove all the water and raising the temperature to distil off the remaining solvent and finally distilling the sulphonylchloride from the sulphone impurities.  The process can be applied to aromatic, aliphatic, isocyclic, heterocyclic and polycyclic sulphonic acids.  Suitable solvents are cycloparaffins, e.g. cyclohexane, and halogenated aliphatic hydrocarbons, e.g. chloroform, carbontetrachloride, 1,2 - dichloroethane, tetrachloroethane and pentachlorofluoroethane.  The solvent can be reused, if necessary after purification.  The reaction is usually carried out below 70 DEG  C., preferably in the range 20-40 DEG  C. after washing the solvent phase, the azeotropic distillation is continued until all the water has been removed, if necessary by adding additional solvent or by recirculating the solvent.  The sulphuric acid phase, from which any small amounts of sulphonylchloride can be removed by washing with solvent, and which may contain unreacted sulphonic acid, can be used for sulphonating hydrocarbons to give sulphonic acids which may be used as starting materials in the present process.  Examples describe the preparation of toluene- and benzene-sulphonylchlorides.

Abstract: 582,805. Rotary pumps. PACKARD MOTOR CAR CO. April 6, 1944, No. 6494. Convention date, April 19, 1943. [Class 110 (i)] [Also in Group XXVII] In a supercharger arrangement, in which an impeller is mounted on an engine-driven shaft, means for neutralizing the effect on the lubrication of the shaft bearing of pressure conditions in the impeller chamber comprise rotary surface contact sealing means which is vented to the atmosphere. A two-stage type of supercharger is described in which impellers 19, 20 are 'mounted on a shaft 22 which is carried in bearings A, B. These bearings are vented by passages 79, 120, the exits being closed by filters 81, 122. The bearing A comprises a two diameter bushing 42, Fig. 2, having a closed end 44 which is held in a hub 24 formed on the casing. At the opposite end a ring 47 is sandwiched between the impeller 19 and a ring 51 provided with oil seal rings 52 and screwed to the shaft 22. A floating bearing sleeve 60 is held in place by a thrust ring 63 and a washer 65. Lubricant is fed by the engine lubricating pump through a passage 66 around the floating sleeve 60 to an annular chamber 68, whence it escapes by a passage 70. The vent 79 is connected to the opposite side of the packing rings 52 by a number of bores 80 in the bushing 42'. The bearing B comprises a two diameter bushing 100, Fig. 5, bolted to the casing, an annular member 104 having sealing rings 105 and a pair of floating sleeves 106 flanged at opposite ends. Lubricant passes from the bearing A up the hollow shaft 22 'and the flow is restricted by a bore in a light-metal insert on 39, sludging being thus prevented. It then passes up radial bores 107, 108 along the floating sleeves and out by a bore 112 to the casing. The vent 120 leads from an annular recess 121 in the packing member 104, and the pressure on lubricant collecting in an annular chamber 111 is thus maintained normal. Pressure on the packing is also relieved by passages 141, Fig. 1, through the impeller 20. The impellers are driven by a pinion 26 on the crankshaft 12 at either of two speeds through planetary gearing. One of several engaged pinions 29 is shown mounted on a shaft 28 carrying a cage 30 which is driven through a oneway overrunning clutch 34. Pinions 41 are engaged by a sun wheel on shaft 28 and a ring gear 33 meshing with a pinion 25 on the shaft 22, and a brake comprises plates 35 alternately engaged with the wall 27 and the hub 36, and normally held disengaged by a spring 38, but operated by pressure fluid, which may be the oil in the engine lubricating system, to hold the sun-wheel shaft 28.
