IPC: B27F7/26
Filed: 1957-02-27
Abstract: 823,442. Locking devices. INTERNATIONAL STAPLE & MACHINE CO. Feb. 27, 1957, No. 6570/57. Class 80 (3). [Also in Group VII] A standard allowing manual positioning of an object such as a mount 23, Fig. 2, for an automatic machine 86 inserting staples into cartons on a conveyer table 24 comprises a hollow track 26 of rectangular section on which is vertically movable a wheeled carriage 21 counterbalanced by a weight 56 movable within the track 26, the carriage being normally clamped to the track by a pneumatic brake. The track 26 is secured to the conveyer table leg 25 by brackets 31, 32 surrounding circular sleeves on the track so that by slackening the brackets the track 26 may be rotated to adjust the mount 23 laterally. The front corner of the track 26 is engaged by upper and lower grooved wheels 45, 46 on the carriage while the two rear walls are engaged by adjustable wheels 35, 36, Fig. 8, mounted within the carriage 21. Compressed air is normally supplied through an electrically-operated valve to a spring-loaded piston 64 mounted in the carriage 21 and actuating a brake element 66 so that the track 26 is normally clamped between the element 66 and brake surfaces 41, 42 on the front plate of the carriage. When it is desired to adjust the height of the machine 86, Fig. 2, the brake is released by actuating a switchbutton 74 to cut off the air supply to the piston 64. After manual positioning of the mount 23 a manual switch Fig. 11 (not shown), is actuated to cause the stapling machine to be lowered by an air cylinder 82 until a contact switch 89 engages a carton, whereafter the downward movement is stopped and air is fed to the machine 86 to effect a stapling operation.

Title: Improvements in the production of ferrous stock for vitreous enamelling
Inventor: BEALL FRANCIS WAYNE
IPC: C23D3/00
Filed: 1957-02-27
Abstract: Ferrous stock for vitreous enamelling is produced by hot rolling, to an intermediate gauge, a ferrous material containing at least 0.02% carbon, cooling the material from above its A1 temperature at a relatively slow rate (50-100 DEG F per hour) to form massive carbides, cold rolling with a reduction of at least 25% without intervening anneal to elongate and fragment the massive carbides. The material may be cooled directly from rolling or may be reheated and cooled to form the massive carbides, and, after cooling, may be normalized, decarbonized, or treated to roughen the surface.  The initial carbon content may be between 0.025% and 0.08% and after decarbonizing may be 0.01%. Specification 674,490 is referred to.

Title: Improvements in or relating to automatic electric switches and closing arrangements therefor
IPC: H01H71/00
Filed: 1953-03-12
Abstract: 722,731. Automatic circuit-breakers. GENERAL ELECTRIC CO., Ltd., and HARKUS, G. N. March 12, 1953 [March 14, 1952]. No. 6681/52. Class 38 (5). In a switch which is reclosed by a solenoid acting on a plunger and thereby on the contacts which are latched in the closed position, the solenoid is energized upon closure of a controller, and remains closed as long as the controller is closed to retain the. plunger in its operated position, even though the contacts have tripped open on fault, thereby preventing. "pumping." Closure of the controller 6 energizes a coil 5 to close contact 4 in the circuit of the solenoid 2 which thereupon closes the contacts 10, at the same time opening a contact 7 and de-energizing coil 5. Contacts 4 open, but solenoid 2 is still energized, but by a reduced current, over resistors 11, 12.

Title: Improvements in or relating to electrical signalling systems
Inventor: HART RONALD IAN
IPC: H04Q11/04
Filed: 1961-02-23
Abstract: 946,254. Multiplex pulse signalling. BRITISH TELECOMMUNICATIONS RESEARCH Ltd. Feb. 16, 1962 [Feb. 23, 1961], No. 6707/61. Heading H4L. In an arrangement for interconnecting two time division multiplex pulse systems controlled by respective timing signals which are independent but nominally of the same frequency and subject to long term drift in order to facilitate the connection of channels of the first system to channels of the second system in a different time sequence, the signals are stored at the interconnecting point in two stores which are used alternately, the changeover from one store to the other being inhibited whenever the phase relationship between two interconnected channels is such that the storage time with normal changeover would approach zero. As shown in Fig. 3, a system A is controlled by digit clock pulses DA1 to DA8 and channel clock pulses CA0 to CA24, CA0 being associated with the synchronizing channel, and a system B is controlled similarly by clock pulses DB1 to DB8 and CB0 to CB24. Each system provides twenty-five channels, each channel period consisting of eight digits and it is assumed that channel 12 of system A is connected to channel 23 of system B in known manner. Two stores S1, S2 are provided for system A which are switched into use alternately by a toggle T1 via a gate G1 or G2, the toggle being controlled by the synchronizing channel pulse CA0. The gates G1, G2 shown are responsive to the channel pulse CA12 and pass the corresponding signal from A to the store in use in that frame period. A toggle T2 is provided for each channel of the B system, that shown being operated by the channel pulse CB23 to pass the output of one or other of the stores S1, S2 via the appropriate gate G3 or G4, controlled by pulse CB23, for transmission by the B system. Whenever the drift is such that the channel pulse CA12 overlaps in time the channel pulse CB23, a pulse is supplied via gate G7 and pulse lengthener PL to inhibit the gate G6 and prevent toggle T2 from being changed over by the next channel pulse CB23, reading of the store S1 being omitted and two readings of the store S2 taking place. Thus, although one frame is not transmitted, difficulties due to the in-phase condition which would mean the loss of many frames are avoided. A suitable store, e.g. S2, Fig. 6, comprises capacitors C1 to C8 connected in turn for the eight digits by gates DAG controlled by digit pulses DA1 to DA8. The extraction of signals from the store is controlled by corresponding pulses from the system B, or connection may be made to further systems C and D via OR gates DNG. The output from the store is passed to system B via gate G3, to system C via gate GC or system D via gate GD.
