Title: Improvements in or relating to the application of sheets to printing machines
IPC: B65H5/10
Filed: 1927-01-15
Abstract: 288,733. Mailõnder, W. Jan. 15, 1927. Sheet-carriers; sheetregistering devices; grippers and gripper mechanism.- Metal sheets are fed to printing-machines by reciprocating grippers 9, 10, attached to a carriage 3 formed of two side plates connected bv cross members 12 to which a fixed member 11 carrying the gripper supports 10 is secured. The pivoted member 9 is held in the open position, Fig. 2, by means of a locking-device in the form of a spring-controlled finger 17 engaging a projection 18 on an arm 19 on the shaft 13 of the gripper. The catch 17 thus holds the grippers open until they move back over a sheet positioned by hand on a support in register with a stop 6. The upper part 11 of the member 10 is tapered and causes the front end of the sheet, even if this is slightly arched, to move correctly over the supports 10, and the gripper 9 closes on the sheet under spring action by operating the clutch 17 by means of a iixed stop 24. The carriage is then advanced by cam-and-lever mechanism 4, 5, which gives the carriage a dwell at the sheet receiving and delivery positions, and also just before reaching the delivery position from which it is taken by the grippers 8 of the impression cylinder 2. The sheet is detached from the grippers 9, 10 by the aid of a stripper which is on a lever-shaft operated by a fixed stop 27. This stripper may be mounted on the shaft of the front stops 29, or the front stops may act as strippers. The sheets when detached from the grippers 9, 10, may be pushed from supports 7 into contact with the stops 29 by means of pushers and may be acted on by side-registering pushers. The stops 6, 29 may be interconnected by lever mechanism, so that the stop 6 is controlled by movement of the stop 29.

Abstract: 413,359. Automatic exchange systems. TELEFONAKTIEBOLAGET L.M. ERICSSON, 33, Kungsgatan, Stockholm. Jan. 16, 1933, No. 1474. Convention date, Jan. 21, 1932. [Class 40 (iv).] In a system in which audio-frequency A.C. is employed for impulsing over a junction, and backward signals of audio-frequency are applied to the junction through a differential transformer so as to produce no effect in the impulseresponding apparatus, the differential transformer is effective only when the backward signals are passing. Seizure of the junction l energizes relay A, and a calling signal from the generator G1 operates relay D through the apparatus M. The selectors are prepared for operation and relay B connects up the generator G2 and removes the normal short-circuits around the differential transformer DT to give the dialling signal. Impulses are then sent to set up the connection, relay B being de-energized to disconnect the generator G2 and restore the short-circuits. The junction normally terminates in a balancing network LB, which is cut out by relay C when switch-through occurs.

Title: Purification of gases
Inventor: NICHOL ROBERT JAMES
IPC: C10K1/10
Filed: 1962-01-17
Abstract: Hydrogen sulphide is removed from a gas, e.g. town gas made by the catalytic cracking with steam of heavy oil, by washing the gas with an aqueous solution containing a ferric iron chelate, in which the chelating agent is an amino acid of the general formula <FORM:0999799/C4-C5/1> in which R is an alkylene group in which at least 2, but not more than 3 carbon atoms separate the N atoms, or is a 1.2 cyclohexylene group; X and X2 is an acetic or propionic acid residue; X1 and X3 is a hydrogen atom, or an ethylol group, or an acetic or propionic acid residue, or, when R is an alkylene group, X3 is a group of the general formula-RNXX2.  The pH of the solution is below the value at which precipitation of iron salts occurs from the solution, but above the value at which hydroxylation of the iron chelate begins.  The pH may be from 2.5 to 9 depending on the acid used.  The R group is preferably an ethylene or trimethylene group, but propylene or isobutylene is permissible.  Preferred acids are ethylene diamine N,N,N1,N1 - tetra - acetic acid, C-methyl ethylene diamine N,N,N1,N1-tetra-acetic acid, 1,2-diaminocyclohexane N,N,N1,N1-tetra-acetic acid, N-hydroxyethylethylene diamine-N,N1,N1 - triacetic acid, diethylenetriamine N,N,N1,N11,N11 - penta - acetic acid, and ethylenediamine N,N1-diacetic acid.  The solution may be reoxidized by passing an oxygen-containing gas, e.g. air, therethrough, or may be effected by free oxygen present in the gas to be purified.  Specification 855,421 is referred to.

Abstract: 904,689. Measuring electrically. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Jan. 19, 1959 [Jan. 17, 1958], No. 1738/58. Class 40 (1). [Also in Group XXXVI] In apparatus for determining the clearance between two ferromagnetic members, a winding 2 on one of the members is connected in series with an inductor or transformer 5 across an alternating voltage source 6 and the rectified voltage developed across the winding 2 is compared with the rectified supply voltage using a self-balancing potentiometer which indicates clearance between the two members. Fig. 4 shows apparatus for determining linear expansion of the shaft of a turbine by measuring variations in the distance d between a ferromagnetic collar mounted on the shaft and the polepieces 1 of an iron-cored coil 2 secured to a bearing housing. Variation in distance d affects the inductance of coil 2 and hence varies the alternating voltage across it. The residual voltage across the coil 2 is reduced by subtracting an antiphased voltage from the secondary of a transformer 5 as described in Specification 900,388. The resultant voltage is rectified and drives a current through a resistor 11. A servomotor 19, controlled by a polarized relay 15, drives the variable resistor 22 until the voltage across the relay 15 falls to zero. The motor 19 also drives a potentiometer 24 which controls a voltmeter 25 to provide an indication of the distance d. In Fig. 3 (not shown), the transformer 5 is replaced by an inductor and the potentiometer 24 and voltmeter 25 are respectively replaced by a variable resistor and an ammeter.

Abstract: 1,073,421. Fluid-pressure brakes. ROCKWELL-STANDARD CORPORATION. Jan. 14, 1966 [Jan. 29, 1965; July 29, 1965], No. 1836/66. Heading F2F. A deceleration-responsive valve 44 of the kind adapted to be inserted in an hydraulic line to rear brakes of a vehicle and including a ball 60 (Fig, 2, not shown) adapted on a predetermined rate of deceleration being exceeded to run up an inclined surface into engagement with a seat to cut off further supply of fluid to the rear brakes, is mounted on a scissors linkage 100, 102 which interconnects the rear axle 80 and the vehicle body 86, the arrangement being such that as the vehicle load increases the angle of inclination of the inclined surface is also increased to cause a corresponding increase in cutoff pressure. In the preferred arrangement shown, the valve 44 is mounted at the upper end of the upper link 100 such that the centre of the ball lies on the axis of pivoting of link 100 on body bracket 90. The effect of jolting as the vehicle travels over rough ground is thereby minimized. This pivotal connection of link 100 to bracket 90, and also the pivotal connections 104, 106 between the links and between the lower link and axle bracket 78, respectively, include rubber bushes to absorb shocks and twisting of the linkage. In an alternative arrangement (Fig. 4, not shown) the valve (44) is mounted on the lower of two links the pivotal connection between which is disposed rearwardly of the axle (80) instead of forwardly as shown in Fig. 7. The geometry of the linkwork is determined by reference to a graph (Fig. 6, not shown) in which front and rear axle weight at varying decelerations from zero g. to 1.0 g. and corresponding braking pressure to give optimum front wheel braking at 1.0 g. are plotted, the rates of deceleration at which cut-off is effected being chosen to suit rear axle load at 1À0 g., where the maximum permitted brake pressure in the rear brakes is least.
