Abstract: 1,115,191. Printing-apparatus; feeding sheets. WAITE & SAVILLE Ltd. 18 Jan., 1965 [17 Oct., 1963], No. 41023/63. Headings B6B and B6C. Feeding sheets and cylinder tripping.-Intermittently pulsed photo-electric cells 19, Fig. 1, are used to detect faulty sheet-feed at the front lays 2 of a sheet-feed device 1. If a fault is detected in the sheet-feed the cell is used to de-energize solenoids which maintain the sheetgripping, damping, inking and impression cylinder trips in operational relationship. Fig. 5 (not shown), depicts suitable circuitry. The sheets are transferred from the device 1 by a cylinder 3. The sheets are transferred from the first unit to the second, Fig. 2 (not shown), by three transfer drums, drums 6 and 10 being shown in Fig. 1, and a further photo-electric cell adjacent the third drum (11) controls the electromechanical tripping of the second unit. A cam 22, Fig. 3, closes a switch 21 so as to pulse the photo-cells 19. If a sheet is fed correctly, a switch (58), Fig. 5 (not shown), .remains in a position (NC) and a switch (59) is temporarily closed after the switch 21 to complete a circuit which energizes arelay (A) and a solenoid, 35, Fig. 3. A lever 34 is oscillated, via a lever 31, by a follower 30 engaging a cam 29 and, when the said solenoid 35 is energized, the oscillating lever contacts a follower 38 on a member 40 and raises a rod 42. Lever 47 is then lowered and a surface 77B engages a pin 80 and moves lever 50 connected to the bushings of the impression cylinder to the operative printing position. The lever 50 closes a switch (51). If a sheet is improperly fed or is absent the switch (58) is moved to position (NO) whereby a relay (B) is'energized via the switch (51). The solenoid 35 is then de-energized and the rod 42 lowered so that a surface 77A engages a pin 79 and the lever 50 moves the impression cylinder into the inoperative position and opens the switch (51). Energization of the relay (A) may control the tripping of the sheet-feed arrangement, the damping mechanism, and the inking mechanism, Fig. 4 (not shown). Rotary printing machines.-The sheets are printed in a two-colour rotary offset machine, each stage including an impression roller 4, an offset roller 5, a printing cylinder 7, and damping and inking units 8 and 9.

Title: Fibre optic connector
IPC: G02B6/38
Filed: 1977-10-06
Abstract: The ends of two individual cladded optical fibres are brought together in a common closure (216). Plugs mounted on the optical fibre ends can be inserted into said closure, the plugs consisting in each case of a bipartite cylindrical collet (11, 12), which contains a groove (111, 121) for accommodating the end of the individual optical fibre. The collet (11, 12) can be clamped onto the assigned individual optical fibre by means of a coupling sleeve (13). The groove (111, 121) of the collet (11, 12) is designed such that in the clamped state its diameter in the coupling region corresponds to the diameter of the non-cladded optical fibre and that its diameter at the opposite end of the coupling region corresponds essentially to the diameter of the cladded optical fibre. The coupling sleeve (13) is constructed in such a way that at the end opposite the coupling region it clamps the collet by means of an interference fit and can be crimped/squeegeed onto the cladded part of the optical fibre. This demountable connection permits an exact and reproducible centring of the optical fibres in conjunction with stress relief. <IMAGE>

Filed: 1972-09-11
Abstract: 1341160 Valves WESTINGHOUSE ELECTRIC CORP 11 Sept 1972 [27 Oct 1971] 42029/72 Heading F2V In a fluid pressure regulating valve, which is designed for controlling high pressure water and/or steam, flow from a high pressure chamber HP to a low pressure chamber LP takes place along a leakage path 33 as indicated by arrows P 1 . The path tapers to a point 35 downstream of which is a leakage passage D which extends through a valve member B into a pressure chamber FB, the valve member, in use, being biased by springs 5 toward a seat surface 19 defined on the housing part H1. The high pressure in chamber HP acts on rear face Al of valve member B to augment the force of springs 5. These forces are augmented still further by the pressure in chamber FB, the latter pressure being a variable one as it is dependent upon the flow through leakage path 33. Cooling water may be injected into the path 33 via line 38 and distribution channel 37. In the basic embodiment, (Fig. 1, not shown), of which the above is a modification, the pressure chamber FB is defined between two concentric bellows, the valve member is limited in its upward movement by an adjustable stop (39), and the force of the spring tending to close the valve is adjustable to a required preset value.

Abstract: 1,056,540. Measuring thermal efficiency electrically. VYZKUMNEY USTAV ENERGETICKY OF PRAHA. Oct. 26, 1963, No.42311/63. Heading G1N. The calorific value of fuel supplied per unit time to a furnace 7 Fig. 1 (not shown), is measured in terms of the air required to burn it, the rate of air input to the furnace being measured by a flowmeter 3, 4 the output signal from which is combined with a signal representing the proportion of unburned air in the furnace exhaust gases, thus providing an indication of the amount of air actually burned. A sample of the gases and combustible remnants extracted at 9, from the furnace, is mixed in a constant ratio with a further air input, regulated by a valve 11 either manually or automatically, then fed to a heat exchanger 12, and completely burned in an oven 14. The exhaust from this oven 14 passes through a cyclone ash separator, 15 and is blown back into the furnace, a sample being taken via a junction 17 to an oxygen analyzer 18 which measures a quantity "α" defined as the ratio of the amount of air introduced into the furnace 7 to the actual amount of air required for complete burning of the fuel. The analyzer may be in the form of an oxygen sensitive inductor Z m , Fig.2 (not shown) with a centre-tapped iron-cored choke T, and a variable inductance Z o  which sets the zero value for calibration purposes. If K is a constant representing the heat developed by a given fuel per unit weight of consumed air when the fuel is completely burned, and V is the flowmeter reading (3, 4), then the required calorific value, Q, is given by Q = K Î 1/α x V. The factor K is introduced at 20, and the signal representing V is delayed in unit 22 to allow for the time of passage of a sample from extractor 9 around the system to the analyzer 18, the output from the unit 19 then representing V Î 1/α. The unit 5 (Fig. 1) compensates the flowmeter reading for any temperature variations in the input conditions to the furnace. The furnace may burn liquid, pulverized, or gaseous fuel.
