Abstract: 853,400. Compressors. WITTEMANN CO. Inc. March 19, 1959, No. 9606/59. Class 8(1). A two stage compressor comprises a first stage cylinder 5 in which reciprocates a first piston 6 and a second stage cylinder 18 which is secured to or formed as part of the piston 6 which reciprocates over a fixed piston 25. The first stage cylinder head 7, piston 6 and piston 25 are all provided with non-return valves 8, 14, 31 respectively which are housed in recesses in these parts. The gas to be compressed enters at 10 and is successively compressed in the cylinders 5 and 18 and passes to the outlet 38, at the same time water is sprayed into the first stage cylinder through a pipe 34 attached to the cylinder head and the position of the valves 14, 31 allows excess water to drain by gravity to the valves where it is discharged in front of the compressed gas, the water acting as both a coolant and lubricant. The cylinder 5 is also cooled by water fed through a pipe 68 to a jacket 63 surrounding the cylinder which is divided into compartments by ribs 64, 65, 66. This water flows from the pipe 68 to a first compartment, through port 70 to the enclosure formed by cylinder 18, piston 6 and a flange 20, through port 71 to a second compartment then through port 72 to the top compartment and out through pipe 73. The water is then fed through passage 74 to a groove 75 surrounding an annular compressed air passage 37, to the space 76 below the flange 20 and hence through port 78 and passage 79 to an outlet 80. A pipe 83 prevents excessive pressures in the space 76 when the piston 6 is moving downwards.

Title: Improvements in regulators for controlling the speed of electric motors
IPC: H02P7/288
Filed: 1928-03-31
Abstract: 292,528. Electrical Research Products, Inc., (Assignees of Stoller, H. M.). June 21, 1927, [Convention date]. Constant-speed control systems.-To maintain constant speed of an electric motor 10, it is mechanically coupled to an inductor generator 13 furrishing alternating current to a Wheatstone bridge 18 with one arm adjusted to resonate to the frequency corresponding to normal speed of the motor, the ohmic resistances of the arms being equal so that normally the alternating voltage in the output diagonal of the bridge is zero. When the speed of the motor and consequently the frequency of the generated current changes, alternating potential from the bridge is impressed upon an amplifying thermionic valve 25 discharging through a transformer 26 into the grid circuits of regulating valves 27, 28, the anodes of which are connected through a transformer 29 directly to the terminals of the inductor generator 13. The circuits are adjusted to give such phase relations between the grid voltages and the plate voltages of the valves 27, 28 as will lead to increased discharge from these valves when the speed increases and to decreased discharge when the speed decreases, the theory of the matter being explained at length in the Specification. The varying discharge from the valves is used, in the case of a direct-current motor as shown in the figure, to vary the strength of an auxiliary field winding 12 which corrects the speed of the motor. For an alternating current motor an arrangement is described in which the varying discharge takes effect upon a saturating winding of a variable impedance device in the motor circuit. Specification 292,530 is referred to.

Title: Improvements in or relating to automatic platen printing machines
IPC: B41F1/08
Filed: 1963-03-13
Abstract: 1,003,073. Printing apparatus; delivering paper; feeding webs. H. MOUNTAIN. Feb. 12, 1964 [March 13, 1963], No. 9881/63. Headings B6B, B6C and B6H. In a web-printing automatic platen machine in which a platen 2, Fig. 1, closes cam-shell-like to meet the type-bed 1, the platen 2 carries the paper web P to the bed, a headstock 3, Fig. 3, mounting intermittently rotating web-moving coacting discs 7 and roller 6, being formed integral with the platen for this purpose. The headstock also mounts a chain drive to the roller 6 comprising a chain 11, sprockets 8 and 9 and a tensioning wheel 10, the drive to the wheel 8 being intermittent and deriving from the machine drive through any suitable shaft 12, 12A &c. The drive to the discs 7 is from the roller 6 through gears 13 and 14, Fig. 6. The platen also carries a guillotine blade 14A by which the printed web is automatically cut into sheets subsequently to its withdrawal from the platen by the discs and roller 7, 6. Prior to platen printing, the web is ruled and perforated longitudinally by a rotary printing device 21 . . . 24, Fig. 3, and a rotary perforator 26, 27, respectively, the web being drawn from a mandrel 19A by a drive deriving from an electric motor 28 through a belt or chain system 29, 30, 30A, positively rotating the perforator and rollers 35. The motor 28 may also drive the printing cylinder 22. The web leaving the perforator is swept by a brush 33 and, due to the operational intermittent nature of the platen machine, loops downwardly where it is engaged to contact a limit switch 32 controlling the motor 28 and thus stop the motor when a predetermined amount of ruled and perforated web is awaiting feed to the platen. Instead of cutting into sheets the printed web may be reeled on a mandrel driven by an electric motor through any suitable slipping clutch. Instead of the limit switch 32, the motor 28 may incorporate an expansible pulley or variable speed means. By arranging multi-passage of the web across the platen multi-impression of the paper in one or more colours may be effected. The apparatus may also embody photo-electric or pneumatic control for automatically correcting any tendency of the paper to wander, for dust extraction at the perforator and for automatically stopping the machine in the event of paper failure. Two or more lengths of paper may be simultaneously fed across a platen from two or more separate reels of paper, if desired.

Title: Production of new organic silicon compounds
IPC: C08G77/06
Filed: 1940-06-06
Abstract: Hard, transparent, glass - like, polymeric organic silicon compounds are obtained by heating, at a temperature of 100-400 DEG  C. and preferably 200-300 DEG  C. and under a pressure sufficient to maintain a liquid phase, one or more unsaturated organic esters of silicic acid, heating being continued until solidification is complete.  The unsaturated esters may be of the types <FORM:0576716/IV/1> <FORM:0576716/IV/2> and <FORM:0576716/IV/3> in which R1, R2, R3, R4 are similar or dissimilar monovalent radicals of the alkyl, aryl, alkaryl or heterocyclic series and one or more of the ester groups contains at least one ethylenic double bond; unsaturated orthosilicic esters of the first four are preferred. Suitable esters are those of vinyl, allyl, crotonyl, isobutenyl and furyl alcohols. Catalysts, e.g. benzoyl peroxide or oxygen, may be employed.  The products have good transparency, scratch resistance and hardness, are insoluble in usual solvents and do not soften at 300 DEG  C.; they may be sawn, turned, ground and polished.  Examples are given of the preparation of polymeric bodies from tetra-isobutenyl, tetra-allyl, triallyl cinnamyl and dicrotonyl diisobutenyl silicates.  Unsaturated orthosilicic acid esters are prepared by replacing ethyl groups in the corresponding ethyl ester-obtained by reacting silicon tetrachloride with ethanol in the presence of benzene and fractionating at 165-170 DEG  C.-by reaction with a large excess of the unsaturated alcohol and distilling off ethanol.  Vinyl silicic acid esters are prepared by passing the silicon ester of ethylene glycol monoacetate through a hot tube.

Title: Selective signalling system associated with a type-printing telegraph system
IPC: H04L17/30
Filed: 1942-07-17
Abstract: 555,458. Selective control. STANDARD TELEPHONES & CABLES, Ltd. July 17, 1942, No. 9968. Convention date, June 26, 1941. [Class 40 (i)] [Also in Group XL] In a type-printing telegraph system in which auxiliary selective operations such as' switching a particular machine into use, are performed by using the code combinations employed for telegraphy, the selection is effected by transmitting (1) a blank signal (e.g. a very long space) which restores. all the controlling relays to normal, (2) a character code signal corresponding to the desired selective operation, this code signal selecting the circuit to be closed, and (3) a second blank signal, which closes the selected circuit. The Figure shows twelve relays F1 ... F12 corresponding to the selective operations, any one of which can be selected by energizing combinations of relays C1...C4, the circuits of which are controlled by sets of relays S1...S4, and M1...M4. The relays S1...S4 are energized in succession by successive spacing currents, and the relays M1...M4 by successive marking currents, irrespective of their duration. The relays C1, C3 are controlled by gas-filled valve VT1 and C2 by valve VT2. The grid circuits of valves VT1, VT2, VT3 include condenser-resistance combinations such as C11, R21 connected to the contacts of the line relays L1, L2, the arrangement being such that the valves VT1, VT2 (and therefore' the relays C1, C2, C3) are only energized by spaces (or marks) of two or more units duration, whilst valve VT3 is only energized by a blank signal of five and a half units duration. The preliminary blank signal causes valve VT3 to energize relay BL to open the circuit of slow-release relay GR which disconnects ground from the lead CG to release any energized S, M, or C relays. Successive spacing and marking pulses (or more correctly the transition from marking to spacing and vice-versa) are repeated by the line relays L1, L2 to relays S1, M1, S2 M2, S3 &c. in turn, and if these spacing (or marking) pulses are of two or more units in duration valves VT1 (or VT2) energize the relays C1, C2, C3, the relay C4 being energized by the third marking pulse (if there is one) irrespective of duration. The second blank signal causes valve VT3 to energize relay BL to complete the circuit of the selected F relay over the armatures of the selected combination of C relays and the back contact of relay M4. The selected F relay locks up over a circuit dependent on relay F12, which can be energized by the combination blank-D-blank. In normal signalling, the fourth marking signal, after the transmission of the first blank, would energize relay M4, which would disconnect the energizing circuit of the F relays. Specification 392,961, [Group XL], is referred to.
