Title: Improvements relating to hydraulic loading means for the rollers of printing machines
Inventor: STAFFORD WILFRID
IPC: F15B11/22
Filed: 1957-12-19
Abstract: 852,429. Printing-machines. MATHER & PLATT Ltd. Dec. 19, 1958 [Dec. 19, 1957], No. 39444/57. Class .100(2) [Also in Group XXIX] Hydraulic loading means for printing rollers of printing machines where the load is applied to the two ends of the printing roller comprises two pistons operating the ends of the roller through piston rods extending through the covers of hydraulic cylinders, the annular area of the piston surface around the piston rod of one piston being equal to the full area of the second piston and the annular piston area in one cylinder being placed in communication with the full piston area of the second cylinder, such that the two ends of the roller will be given equal movement when the annular area of the second piston is connected to exhaust and hydraulic pressure is applied to the full area of the first piston. As shown, a printing roller a is moved towards an impression surface b by piston rods g and h carrying pistons e and f respectively. The pistons e and j slide in cylinders c and d respectively, the top s of cylinder d being connected to the bottom u of cylinder c by a pipe q. Hydraulic pressure applied to the bottom t of cylinder d causes the piston f to supply fluid to the bottom u of cylinder c and since the annular area of the top of piston f is equal to the area of the lower side of the piston e the piston rods g, h are moved equal amounts. When the roller a engages the surface b, valves k and m are set to the Fig. 2 position to open the tops r, s of the cylinders to exhaust and the bottoms u, t to hydraulic pressure from sources j and i respectively. When it is required to retract the roller a, the valves k and m are set to the Fig. 3 position to supply hydraulic pressure to the tops r and s of both cylinders, the bottoms u and t being opened to exhaust. If desired, the roller may be returned to its initial position by spring pressure instead of hydraulic pressure.

Abstract: 875,318. Centrifugal compressors; stuffing- box substitutes. GARRETT CORPORATION. Dec. 20, 1957 [Dec. 21, 1956], No. 39676/57. Classes 110 (1) and 122 (5). In a refrigerant compressor operating with its suction pressure below atmospheric, the pressure in the space 60 between a carbon ring seal 36 and a labyrinth seal 30 is reduced to a low value to minimize leakage past the seal 36 and to reduce the axial thrust on the impeller 10, this low value being maintained slightly above atmospheric pressure to prevent leakage of air into the refrigerant circuit. For this purpose, the space 60 is connected to the compressor inlet via ducts 61, 62 and 66, a valve 65 and a duct 68. The valve 65 is actuated by a diaphragm 73 exposed on one side to the pressure in duct 66 and on the other side to atmospheric pressure and the force of a spring 83, whereby the pressure in space 60 is maintained slightly above atmospheric. The spring force can be adjusted by a screw 85. Specification 875,319 is referred to.

Title: Phase Shifting Network
Inventor: PARKYN DEREK JOHN
IPC: H03H7/21
Filed: 1968-08-22
Abstract: 1,163,260. Phase shift circuit networks. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 22 Aug., 1968, No. 40220/68. Heading H2F. [Also in Division H3] A phase shifting network, e.g. for colour T.V., provides first and second output signals in quadrature at terminals 10, 11 and 12, 13 respectively, from a common input signal at terminals 4, 5. In the absence of the other circuit components an in-phase component of the input signal would appear across a resistor 7 and a quadrature component across the primary of a transformer 6. However the connection of the primary of a transformer 8 across R7 will result in a phase change of the signal across R7. This phase change is eliminated by a capacitor 9 which resonates with the primary of 8 at the input signal frequency. The input signal is from an output transistor 2 fed by a local oscillator 1 for regenerating a carrier on which received colour signals are quadrature modulated. Floating outputs in quadrature are fed to synchronous demodulators 14, 15 from the secondaries of 6 and 8 respectively. A capacitor 16 forms a second tuned circuit with R7 and the primary of transformer 6 (taking into account the other components) tuned to the input frequency and will act as a filter for any harmonics generated by oscillator 1.

Patent GB-408830-A (GB)
Abstract: 408,830. Liquid-fuel burner apparatus. AKTIEBOLAGET ROTOMATOR, 28, Jakobergsgatan, Stockholm. June 7, 1933, No. 16357. Convention date, June 8, 1932. [Class 75 (i).] The closure of a thermostat 9 subjected to the temperature of water leaving a boiler completes a circuit through contacts 14, 17 arranged in the boiler flue to a solenoid 21 and thereby raises a pivoted arm 24 to close a mercury switch 19 supplying current to the ignition transformer 26 of the liquid fuel burner 3 heating the boiler. A finger 37 on the arm 24 engages during its upward movement a pivoted arm 28 and depresses it against the resistance of a spring so as to close a mercury switch 20 through which current is supplied to operate an electromagnetic fuel valve 32 and to rotate the burner motor 4. In normal operation the fuel discharged by the burner becomes ignited at the sparking gap 27 and the heat of combustion causes the arm 13 carrying the contact 14 to turn to the left, the contact 17 being maintained in contact with the contact 14 by a spring until after the contact 14 has engaged a contact 18 mounted on an arm 16 which turns with considerable friction on its pivot 36. The engagement of the contacts 14, 18 completes a circuit to an electromagnet 22 which holds the switch 20 closed after the contacts 14, 17 have separated to break the circuit to the solenoid 21 until the water temperature opens the thermostat 9 when the switches return to the positions shown. During the movement of the arm 13 to the right on cooling the arm 16 is drawn also to the right by a stop 35. A switch 12 is operated to cut off the main current by a member 33 heated by the current passing through the switch 19 if ignition of the fuel does not occur after a predetermined time or by a member 34 arranged in parallel to the contacts 14, 18 if these contacts become separated owing to failure of the flame. The members 33, 34 also operate the switch 12 if the glass of the switches 19, 20 is rendered conductive by becoming covered with a film of mercury. If the main current supply is alternating the solenoid 21 and electromagnet 22 are supplied with low tension direct current by means of a transformer and rectifier. The switches 19, 20 may be operated mechanically or thermally instead of electrically and the members 33, 34 may be operated by a clock mechanism instead of the electro-thermal means described.
