Title: Improvements in and connected with hydraulic and other fluid pressure jacks
IPC: B66F3/42
Filed: 1926-11-22
Abstract: 290,688. Miller, H. C., and Sumner, G. P. Nov. 22, 1926. Safety-valves. - To prevent injury due to generation of excessive pressure in a fluid pressure jack, an adjustable spring- pressed safety valve is mounted in the base of the jack so as to normally close a port connecting the ram cylinder and the reservoir. The base 1 of the jack is formed with a recess 10 which communicates by ports 6, 9 with the ram cylinder 7 and reservoir 11, respectively. The port 6 is normally closed by a spring-pressed safety valve 2 provided with an aligning collar 5, the spring abutting against an adjustable screwed plug 4. A ball valve may be used instead of a conical valve. When the pressure in the ram cylinder becomes excessive, the valve opens and pressure fluid escapes into the reservoir. In a modification the valve is vertically mounted in a sleeve screwed into the base. The valve 16, Fig. 3, may be mounted on a leaf spring 15 which is adjustably clamped to the base by a screwed stud 18 and clamping plates 17. The leaf spring 15, Fig. 4, may be curved and the ball valve 20 secured in a recess in a valve support 16<a>. The leaf spring 15, Fig. 5, may be secured to a bracket 22 mounted on a pivot 23 and fitted with a screwed stud 24 for adjusting the spring tension.

The central portion of the unit is of angle section, having two serrated faces 9, 10, for clamping engagement with the serrated faces 4 of sleeved units 1 on transverse bracing members 3. The units have holes or slots 11 for receiving bolts 19 which clamp the units together. Additional transverse or diagonal bracing members 3 are attached at intermediate points to a tube 7 by a coupling unit 2<a> on which a serrated plate 14 is pivotally mounted, the plate and unit being locked in the required positions by screws. In a modification, the unit comprises three serrated wings 20, 21, 22, Fig. 2. The wings 20 and 21 are bent from a piece of sheet metal which is formed with a bend 23 between the wings for engaging the tube or upright 7. The wing 22 comprises two plates 24, 25, which are hinged at 28 to the wings 20, 21, respectively and which are curved at 26 to embrace the tube 7. The two plates of the wing 22 are clamped together by bolts 29 which may be separate as shown or may be pivotally mounted on one of the plates. Other methods of interconnecting the hinged wings are also described. The transverse bracing members 3 may be secured to the coupling units on the upright tube 7 by a unit comprising two hinged sections which form a clamping sleeve 47, Fig. 2, and a wing 46, the latter being connected to a serrated face of the unit on the tube 7 by bolts which may serve also to clamp together the two leaves of the wing 46. The plane of the wing may be tangential to the sleeve or it may pass through the axis thereof. In a further construction, Fig. 9, the wing 51 is integral with one half of the sleeve 52 to which the other half is hinged at 54, the two parts being clamped together when in position by a bolt 53. In the modification shown in Fig. 12, a subsidiary coupling device is mounted on one of the hinged components 48b of a serrated wing. This subsidiary coupling comprises two channelled straps 62 between which is clamped a transverse tubular section by means of a bolt 63.

Abstract: 1352708 Error correction system HONEYWELL INFORMATION SYSTEMS Inc 28 June 1971 [3 Aug 1970] 30225/71 Heading G4C Error correction system for data recorded with alternate data bits and clock pulses on two tracks of a magnetic tape, eachwordon one track having an even parity bit with the same word on the other track having an odd parity bit, compares corresponding data and parity bits to replace a missing data bit. Data from the two tracks are read to AND gates 62, 64, respectively, and to an OR gate 50 feeding monostable multivibrators 58, 60 arranged to gate the data pulses through the AND gates and to remove the clock pulses. The number of bits in each word is counted in counter 70 and corresponding bits of the words in buffer register 40, 42 are compared in exclusive OR gate 80. If the bits differ a data bit error signal is produced. The data bits are fed via OR gate 20 to a shift register 28 to combine missing "1" bits and to a parity generator the outputs of which, Odd and Even, are fed to AND gates 102, 104 receiving signals from AND gates 22 indicating whether the parity signal at the end of each word was odd or even. If a discrepancy occurs a word sync. error signal is produced. Counter 70 indicates the end of a word period and counter 75 indicates the number of errors present in the data bits. A word End Marker Error is produced by gate 114 if the parity bits on both tracks are both "1" or "0". If a clock pulse is missing from the tape in the same position in both tracks a data bit is lost and the counter 70 will not generate a word clock until after the word and the dissimilar parity bits will not be detected and so create a Word End Marker Error signal.

Title: Improvements in electrolytic detinning
IPC: C25C1/14
Filed: 1962-08-07
Abstract: <PICT:1013521/C6-C7/1> A process for the electrolytic detinning of tin-coated scrap material comprises subjecting the scrap material to electrolysis in an autoclave 1 containing an aqueous alkaline electrolyte, the wall of the autoclave being the cathode and the scrap material within an anode cage 17 being the anode, and maintaining the electrolyte under pressure at a temperature above the melting point of tin, whereby the tin is deposited on the autoclave wall and flows downward in a molten state to the bottom of the autoclave from whence it can be tapped at 6.  Prior to loading and unloading the anode cage 17 into and out of the autoclave, the electrolyte while hot and under pressure can be transferred from the autoclave to a thermally-insulated pressure-resistant storage container through a passage 8 by a pump 12.  The anode cage 17 comprises a lattice of steel bars and has a stainless steel bottom which seats on an anodically connected stainless steel base 18. Electrolyte level indicators 32, 33, 36, temperature and pressure indcators and valves, including a pressure safety valve 25 for venting gases liberated, are provided which allow a certain degree of automatic control.  Fresh electrolyte in a reservoir 35 can be pumped at 34 into the autoclave.  The alkaline electrolyte may be an aqueous solution of NaOH which may contain additives such as KOH, NaCl or NaNO3.  The autoclave 1 is heated by hot gases within a heating jacket 45.  An electrolyte temperature above 231  DEG C., a pressure of 35 atmospheres and reduction of tin content to below 0.01% are specified.  A small flow of an inert gas such as N2 is supplied to the autoclave at 19 to prevent the O2 and H2 released by electrolysis forming an explosive mixture.  In order to reduce foam formation in the electrolyte, an anti-foaming agent can be injected into the apparatus through a nozzle 37.  Prior to detinning tin cans, the cans are partially crushed and perforated and may be cleaned.

Abstract: 997,723. Measuring torque electrically. LICENTIA PATENT-VERWALTUNGS-G.m.b.H Aug. 9, 1962, No. 30580/62. Heading G1N. A torque measuring apparatus comprises an electromagnetic transmitter fitted to and rotating with rotary driving and driven members 10, 12 and which includes an oscillator the frequency of which is torque dependent, and a stationary electromagnetic receiver which is frequency sensitive. A hollow shaft 10 coupled to a motor, the torque/ speed relationship of which is to be evaluated, is capable of restricted angular movement relatively to a housing 13 terminating in a coupling 21 itself connected to a mechanical brake. A torque rod 11, which may be replaceable to suit different motors, is joined at one end to the shaft 10 and at its other to a ring member 12 itself connected to the coupling 21 by grub screws. The driving torque of the motor causes the rod 11 to twist and axially displace a core 17 relatively to a coil 19. The core 17 extends normally to, but is displaced from, the axis of rod 11 and is mounted on the shaft 10 by brackets 16, the coil 19 being secured to the housing 13. The frequency of an oscillator comprising transistor 18 and powered by batteries 23 is controlled by the inductance of the coil 19 and hence produces a signal which is torque dependent, and is radiated from an antenna 20. The receiver, which may be of the superheterodyne type, converts the variable frequency signal to D.C. and energizes a recording device which may include a second channel on to which the voltage output from a unipolar tacho-generator, driven from the motor under test, is also recorded.

Filed: 1932-10-31
Abstract: 396,253. Rotary engines. GIRARD, E. P., GIRARD, J. A., and EMCH, R., Grenchen, Switzerland. Oct. 31, 1932, No. 30610. Convention date, Nov. 1, 1931. [Class 110 (ii).] A rotary internal-combustion engine of the geared-vane type comprises outer and inner rotors 18, 20, with co-operating radial vanes 25, 29, respectively. The inner rotor is keyed to a shaft 12 mounted in bearings and sleeves 14, 16, 17, 100, 19, and the outer rotor 18 is fixed to an annular shaft 13 supported by a bearing 15 and the above sleeves. Packing rings 34, 35, 38, are provided. Eight inlet valve chests 47 and eight exhaust valve chests 49 revolve with the outer rotor. Two discs 9, 10, connected to each other and to the rotor 18, support two pinions 2 on pins 3. The pinions mesh with internal teeth on stationary rims 1 so that during the rotation of the rotor 18, and the pins 3, the shaft 12 is given an alternate acceleration and deceleration through the connecting links 5, 7. This motion is transmitted to the vanes 25, 29, to cause expansion and contraction of the working chambers. Fuel gas is led to the valve chambers 47 through a conduit 53 to a port 54. Sparking plugs 50, inlet ports 51, and exhaust ports 52 are situated on each side of a radial vane. The plug contact gear is shown to the left of Fig. 1 and comprises a bell-crank lever 68 with a contact 71 kept apart by a spring 69 until a knob 72 on the rotor plate 10 forces the contact gear together, At the time of breaking contact a plug is passing near an energised shoe so that a spark jumps from the shoe to the plug, and also across the plug points. The interior of the rotor 20 is cooled by oil which flows through a pipe' 55 and port 56, and is circulated by a rotating disc 57. Oil passes to lubricating points 58 and leaves through a port 59 to an outlet 60 and pipe 62. A flywheel 11 is fixed to the shaft 13. Cams on a ring 64 operate the inlet valves 39, and cams on a ring 65 actuate the exhaust valves 48. Instead of two toothed rims 1, one or more than one may be provided arranged concentrically but in different parallel planes. The gearing may be replaced by a roller clutch mechanism in which the rotor 20 is intermittently clutched by the outer heavy rotor 18. In a further arrangement two discs rotate around fixed eccentric cams and connect cranks and levers attached to the two shafts 12, 13, to secure the relative motion between these shafts. Several engines may be built on one block, the engines being controllable individually. The inlet and exhaust valves may be replaced by sleeve valves.
