Filed: 1946-06-26
Abstract: 600,349. Lamp - holders. CROMPTON PARKINSON, Ltd., and JONES, T. S. June 26, 1946, No. 19136. [Class 38 (i)] A holder for a double-ended tubular lamp comprises a body 1 having an entry slot 3 for the lamp pins communicating with a rotatable locking device 2 housed in the body, the latter having a bevelled surface 5 extending across the entry to said slot 3, Two such holders are mounted on flexible L-shaped metal brackets which can be sprung apart by lamp caps bearing on the surfaces 5 on the holders to facilitate entry of the lamp pins, the flexibility of the brackets then urging the holders together to ensure good contact between them and the pins. Fig. 4 (not shown) illustrates a holder of the pillar type having a bevelled surface, the mounting bracket in this case being of U-shape. The bracket may be integral with the holder or between the holder and bracket.

Abstract: 1370394 Measuring transistor current gain WELWYN ELECTRIC Ltd 30 March 1973 [26 April 1972] 19332/72 Heading G1U The variation in the current gain of a lateral transistor 1, Fig.1, caused by the application of strain to the transistor, is detected by arranging the transistor in a circuit which oscillates at a frequency proportional to the current gain. As shown the voltage across the collector load 28 of the transistor is integrated 5, 6, and whenever the output of the integrator reaches a level set by a potential divider 10, 11, a threshold circuit 8 responds to energize a solenoid 29 which causes the integrating capacitor to be shunted by a contact 7. Typical output waveforms, which may be taken from a terminal 15 are described Figs. 2, 3 (not shown).

Title: Cutting and creasing press
IPC: B26D1/30

Abstract: 727,119. Cutting-machines. S & S CORRUGATED PAPER MACHINERY CO., Inc. July 13, 1953 [July 29, 1952], No. 19406/53. Class 31 (1). [Also in Groups II and XVI] A press for cutting and creasing cardboard and other blanks, e.g. for producing box-blanks, comprises a die 31 supported on a bed 30, a curved member 35 arranged to roll on the die, and means for feeding a blank to one end'of the die and withdrawing it from the opposite end, both the feed and withdrawal occurring when the curved member is at the other end of the die. The member 35 is shown as a quadrant rotatably carried by a shaft 36 in blocks 37 riding in guide slots 38 in supports 39 disposed above the die which has upstanding cutting and creasing blades. The blocks are reciprocated to cause the quadrant to roll by means of crank mechanism 41, 43 driven from a motor 11 through chain-and-sprocket gearing 16 ... 19, slip between the quadrant and die being prevented by gear teeth 50 on the rack engaging fixed racks. The chain-andsprocket gearing also drives crank mechanism 83, 84 for feeding a blank to the die when the quadrant is retracted, and crank mechanism 143, 145 for withdrawing a finished blank when the quadrant is advanced. The blanks to be operated upon are fed from a hopper 60 having front, rear and side gauges 61, 62, 63, of which the gauges 62, 63 are adjustable to the size of the blanks being cut. The lowermost blank in the hopper is fed by a slat 70 carried by posts 72 on blocks 81 slidable on rods 82 by the crank mechanism 83, 84. The slat 70 is connected to the posts 72 by bolts 76, being urged upwardly by springs 78; the slat may be of resilient material and chamfered at its rear edge. The finished blank is withdrawn from the die by being gripped by two pairs of spring fingers 102, 103, each pair of which is carried on a block 104 mounted on a slide block 140 reciprocated along a rail by the crank mechanism 143, 144. Each finger 103 is hinged to the finger 102 and its movement to and from gripping engagement is controlled by an arm 110 having a roller 111 co-operating with cam tracks 115, 116; a spring 107 urges the finger 103 to. open position. As the blocks move inwardly during a pressing stroke of the quadrant, the fingers 103 are held open as-long as the rollers 111 run on the track 116; at the end of this movement, the fingers' 103 coact with the fingers 102 to grip a finished blank by the passage of the rollers 111 up an incline 117 and past a spring-pressed door 120 on to the upper track 115. The blank is then withdrawn by the retracting movement of the blocks 104, at the end of which the rollers 111 drop off the track 115 so that the fingers release the blank which drops on to a transverse endless conveyer 130. In a modification, the quadrant co-operates with the underface of the die which is then fixed beneath the bed 30.

Abstract: 1319217 Electric correspondence control systems CINCINNATI MILACRON Inc 26 April 1972 [26 April 1971] 19447/72 Heading G1N In a grinding machine control system, the size of a workpiece 14 (Fig. 1) is continuously monitored by gauge 22 to determine the amount of material still to be removed, and the power input to the grinding tool 10 is measured at 36 to determine how much material would be removed if the power were cut off. When these are equal, the feed mechanism 16 is cut off or reduced in speed and the grinding process finishes with the resultant workpiece surface of consistent smoothness. When the workpiece reaches the desired diameter a zero detector 31 causes the tool to be withdrawn from the workpiece 14.

Abstract: 1422740 Automatic control of aircraft BODENSEEWERK GERATETECHNIK GmbH 26 April 1973 [10 Oct 1972] 19921/73 Heading G3R  An aircraft flight controller has all the condition  variables relevant to the aircraft performance applied to all the controlling servomotors simultaneously so that an optimum control is obtained. Some of the servomotors may be preceded by further elements to give an enhanced performance and preferably the system is provided with some redundancy. In the arrangement shown the angle of attack α is measured at 10 and compared at 18 with the required value to give an error signal #α. An anchrometer 12 provides longitudinal (u) and vertical (h) acceleration signals and a rate gyro 14 provides a rate of change of pitch angle signal wy. An altimeter 16 provides a height signal which is compared with a required height signal to give an error signal #h. The unit 34 contains integrators and high and low pass filters having the characteristics shown to provide the condition variable function outputs 1-10 which are supplied directly to throttle servomotor 26, through filter 35 to spoiler servomotor 30 and through computer 32 to servomotor 28. The computer 32 provides a dynamic pressure compensation to account for the change of elevator efficiency with aircraft speed. The filter 35 ensures that the spoiler lift flaps do not operate during normal flight. The elevator servomotor 28 is supplied directly with a signal computed from the error in angle of attack and the physical characteristics of the mechanical link to the elevator surface which is modelled in filter 56. Redundancy is ensured by providing that many of the controlling factors on terminals 1-10 can be derived in two ways at least.

Title: Safety device for fuses of all kinds
IPC: F42C9/14
Filed: 1924-08-27
Abstract: 221,217. Pantoflicek, B. Aug. 27, 1923, [Convention date]. Projectile fuzes.- Relates to fuzes in which, when the projectile is at rest, a safety device obstructs the flash passage or passages, the safety device being moved after the discharge to free the passage or passages. According to the invention, the safety device is adapted to be set before the projectile is discharged, and when moved after discharge allows the flash to pass to the charge either with or without delay according to the setting. In the construction shown in Fig. 1 there are two flash passages 4, 5 one containing a delay device 23. The safety members comprise two laterally slidable pistons 6, 7 pressed inwards by springs to obstruct the passages 4, 5 when the projectile is at rest and adapted to be thrown outwards to free the passages when the projectile rotates. The pistons are locked by safety pins 21, one or other of which is removed to arm the fuze. In a modification, there is only one piston 30, Fig. 3, having two passages 37, 38 one of which contains a delay device 39. Two stops 40, 41, one of which is removable, are provided to ensure that either the passage 37 or the passage 38 shall register with the flash passage 35 when the projectile rotates. The centre of gravity S is near the axial line of the fuze so that the centrifugal force is insufficient to overcome the friction of the piston in its cylinder until the acceleration of the projectile ceases. The safety piston may be locked in the safe position by a cap or other member which falls off during the flight of the projectile, or its movement may be delayed by suitable means. The safety member may be given forms other than a piston and may be moved by means other than centrifugal force, for instance by the firing of a charge.
