Title: Improvements in locks for doors or the like
IPC: E05B27/00
Filed: 1923-01-05
Abstract: 211,299. Tyler, J. W. Jan. 5, 1923. Locks, revolving-barrel; lock mechanism, master-key.-A slotted sleeve E, fitted between the barrel A and housing B of a revolving-barrel lock of the pin-tumbler type, can be set by hand, after insertion of the key, to render the locking pins C inoperative so that the latch can be operated by hand either for as long as desired or, under certain conditions, once only. The sleeve E is provided with rows of perforations E<2>, E<8> separated by a slot E<7>, an operating collar H, and an extension E<4> provided with perforations E<3> and an aperture E<5>. A handle F, attached to the barrel A, has a hub portion F<2> surrounding the extension E<4> and carries locking pins G. The perforations E<2>, E<5> and E<3> when registered with the pins C, G, holds the latter inoperative but are large enough to receive the smaller operating pins D to allow the key to be withdrawn. A spring-pressed plunger J, with bevelled end J<2>, is provided in the housing B and is adapted to be engaged in one or other of the slots H<3>, H<4> in the collar H. The locking pins C, G are normally situated in the slot E' and aperture E<5> respectively. With the plunger J in the slot H<3> and the key inserted in the lock, the sleeve E can be set by hand so as to register the perforations E<2>, E<3> with the pins C, G, when the key can be withdrawn. The latch can now be released by rotating the handle F, whereupon the pins G drop into the aperture E<5> and, as the latch and barrel return, engage the edge E<6> of the aperture E<5> to return the sleeve to its initial position and so render the pins co-operative again. With this arrangement the key must be re-inserted after each operation of the handle F. If it is desired to hand operate the latch without having to use the key after each operation, the plunger J is arranged to work in the slot H<4>, when, after insertion of the key, the sleeve E can be set by rotating it to its full limit in the slot H<4> so as to register the perforations E<8> with the pins C. Upon now rotating the barrel by the handle F, the pins G will work idly in the aperture E<5>. The plunger J may, if desired, be inserted through a hole H<9> in the collar H after the lock is assembled. In order to enable the lock, under certain circumstances, to be operated by a certain type of key and under other circumstances by a master key only, a perforation E<10> is provided in the sleeve E so that, with the plunger J in the slot H<4>, the sleeve, on being rotated to engage the end J' of the plunger against the ridge, H<6>, brings the perforation E<10> into register with the end pin C of the lock and renders the latter inoperative. In this condition, the lock can be operated by a certain type of key, but, on returning the sleeve E to its initial position, the end pin C is released and the lock can only be operated by a master key. More than one perforation E<10> may be provided. The sleeve may be provided with a pointer H' and the end face of the barrel housing with co-operating index marks.

Title: Door-closer comprising detent means
IPC: E05F3/22
Filed: 1977-01-07
Abstract: The closing spring (4) is supported via a roller (6) on a cam disc (7) having a catch recess (9, 9') the closing effect of the closing spring (4) being capable of being cancelled by the catch recess. For the selective cut-in and cut-out of this stop device, there is provided, on or in the cam disc (7), at least one externally actuable switch bolt (13, 13') which, in one position, allows the roller (6) to penetrate and, in its other position, prevents the roller (6) from penetrating, in that it projects into the catch recess (9, 9') of the cam disc (7). Thus, the stop device can, as desired, be cut in or cut out according to the particular requirement, for example that the door, when opened completely, should remain open in a warm season, whereas, even when opened completely, it should close again immediately in a cold season. <IMAGE>

Title: Data processing apparatus
IPC: G06K17/00
Filed: 1974-01-04
Abstract: 1450283 Sorting data INTERNATIONAL BUSINESS MACHINES CORP 4 Jan 1974 [2 Feb 1973 (2)] 00491/74 Heading G4M Data having a class address is entered at random into a recirculating shift register store 1. Each class address may be associated with a plurality of items of data which are to be read out in each class in the order in which they were entered, e.g. the data may represent cheques. Data from a keyboard or from a reader is fed to an input register 12 serial by character with the bits of each character in parallel. The register 12 has one more stage than is required to hold the characters from each document and this stage 20 holds the class address for the document supplied from encoder 19. The store 1 is supplied with a code BOC identifying the start of the store and is filled with blanks. During circulation of data in the store detection of a BOC code by unit 50 and of a blank by unit 51 causes AND gate 6 to be inhibited and the data from register 12 to be synchronously shifted into store 1. A counter 48 counts the number of shifts to stop further entry when the data is all entered. Documents from which the data is taken are sorted into respective pockets and when a pocket is filled a switch 31-1 to 31-u is operated to generate readout of the store. The switches feed an encoder supplying the class address to register 35 which is coupled to comparator 78 which also receives the output of memory 1. When the addresses agree data is read from store 1 and printed by printer 40 on to tape 47. When all characters in the store have been read and the space signals are detected the tape 47 is advanced, torn off the roll and fastened round the records taken from the full pocket.

Filed: 1929-01-07
Abstract: 303,750. International General Electric Co., Inc., (Assignees of Allgemeine Elektricitats-Ges.). Jan. 7, 1928, [Convention date]. Controllers, actuating mechanism .-In rotary switching devices adapted to be held in an operative position by a spring-pressed member engaging a notched disc secured on the switch-shaft, a transmission mechanism is interposed between the spring and the motor-engaging member, or the notch-engaging member may itself be suitably modified to cause an increase in force exerted by this member as it is forced into the notch. As shown in Fig. 1, the mechanism employed consists of toggle links k arranged so that the angle between them increases as the roller r moves into the notch of the disc s. Thus although the force exerted by the spring may be decreased, the action of the toggle increases the holding force as the roller moves towards the bottom of the notch, giving a reliable indication that the switch has reached an operative position. A stop may be provided for preventing the toggle from being completely straightened. In a modification, Fig. 2, the notch-engaging member may consist of a star-shaped member r, two adjacent spokes of which engage the sides of adjacent notches when the switch is in an operative position. The spring f may engage the lever carrying the member r directly, as shown, or through toggle mechanism of the type shown in Fig. 1.

Abstract: 833,261. Turbine and compressor blades. WIGGIN & CO. Ltd., H. Dec. 31, 1957 [Jan. 7, 1957], No. 599/57. Class 110 (3). [Also in Groups II and XXII] A turbine or compressor blade comprises a matrix 1 of a creep- and heat-resisting alloy surrounding and stiffened by rods 2 of molybdenum or a molybdenum-base alloy. The matrix alloy may have a base of nickel and chromium, or nickel, chromium and cobalt, hardened by aluminium and titanium. The blade is manufactured by inserting the rods in holes drilled in a billet of the matrix alloy, the billet being extruded through a die. The blade shown is formed from a billet 1¢ inches square of an alloy having a composition 58% nickel, 20% chromium, 16% cobalt, 0.08% carbon and small amounts of aluminium, titanium, manganese, silicon and iron, the billet being drilled with blind holes each # inch in diameter, the inside surfaces of the holes being plated with nickel. The molybdenum rods 2 are initially 3/32 inch in diameter, are coated with gold, then palladium, and finally nickel and are then inserted into the holes, being sealed in position by a nickel weld on the end of the billet. The billet is heated for 40 minutes at 1150‹ C. and then extruded to form a blade section 1¢ inches in chord width. The blade is heat treated by heating for 4 hours at 1150‹ C., cooled in air, heated for 8 hours at 1080‹ C. and then cooled in air, this treatment causing diffusion between the various layers and good bonding between the matrix and the molybdenum rods. If the blade is to be provided with cooling passages 3, some of the holes drilled in the billet may be filled with a filler, e.g. an iron, manganese, titanium alloy, which is finally removed. The billet may be only partially extruded through a die so as to leave a portion from which the root may be formed. The holes forming the cooling fluid passages may extend completely through the billet. The stiffening rods are preferably a molybdenum base alloy containing at least 80% molybdenum, e.g. an alloy containing 99.5% molybdenum and 0.5% titanium. Other such alloys contain a small amount of zirconium, vanadium or niobium.

A relief valve comprises a main valve chamber 8, a main valve 11, arranged to open when the pressure within the main chamber falls below a predetermined minimum value, a second chamber 7 in restricted communication with the main chamber and incorporating an auxiliary pressure relief valve 22 for opening the second chamber to exhaust when the pressure within the valve exceeds a predetermined maximum value, and means for opening the main valve in response to a substantial fall in the pressure within the second chamber with reference to the pressure within the main chamber. The valve 11 is connected to a diaphragm 5 which separates the chamber 8 from the second chamber 7, the valve being urged into the closed position by a spring 15 abutting a body portion 2. The valve 22 is actuated, via a lever 21, by a diaphragm 4 defining a wall of an intermediate chamber 6. In operation, if an excess pressure occurs in the main chamber 8, it is communicated first to the chamber 6 via a restricted passage 9 and then to the chamber 7 via a restricted passage 10. Movement of the diaphragm 4 actuates a lever 21 thereby opening the valve 22 and so exhausts the pressure in the chamber 7. Due to the restricted passages 9, 10, a pressure differential occurs between the chambers 7, 8 and thus causes the main valve 11 to open. The diaphragms 4, 5 may be of neoprene.
