Patent GB-972706-A (GB)
Title: Conveyor for packing machines
IPC: B65B35/20
Filed: 1961-01-26
Abstract: 972,706. Conveying articles. K. KÍRBER. Jan. 26, 1961 [Feb. 10, 1960], No. 3078/61. Heading B8A. A conveyer for feeding articles step by step in a packaging machine comprises pushers 30 which displace the articles along surface 52. The movement of pushers 31 is compounded of two movements stemming respectively from rods 26 and 44 driven with out-of-phase movement by gear 46. Rod 26 is pivotally connected to U-beam 15 and causes the beam to reciprocate, the beam being carried by carriages 14, 20 and 13 which respectively slide along the bars 12, 18, 19 and 11. U-beam 15 carries pushers 30 pivotally at 33 so that the movement of rod 26 causes the longitudinal movement of pushers 30. Rod 44 is pivotally connected to slide 37 which slides along rod 40 carried by carriage 20. Slide 37 carries rigidly rail 36 wherein are formed slots 35 which co-operate with respective rollers 34 carried by the pivoted pushers 30. Movement of rod 44 causes reciprocation of slide 37 and therefore of slots 35. Since the rods 26 and 44 are out of phase it follows that the movements of slide 37 and carriage 20 are also out of phase. This causes relative movement between a slot 35 and a pusher 30 and this relative movement causes the upward movement of pusher 30. As a result, a pusher rises behind a package to give it a push leftwards, is lowered so that it may be retracted, and then elevated in order to give the next package a push.

Patent GB-1456099-A (GB)
Title: Pneumatic lung analogue
IPC: G09B23/28
Filed: 1974-01-24
Abstract: 1456099 Lung analogue for testing respiratory apparatus MICHIGAN INDUSTRIES INC 24 Jan 1974 [29 Jan 1973] 03300/74 Heading A5R A pneumatic lung analogue for testing respiratory apparatus comprises a pair of bellows 36 each secured at one end to a top panel 18 of a support case 10 and at its other end to a movable end plate 26 or 26a, the movable plates being rotatably secured to brackets 28, 30 so that when the bellows are inflated by inflowing air from respiratory apparatus under test through precalibrated tubes 47, 42 and 42a simulating the resistance of a respiratory tract the ends of the movable plates indicate for a preset bellows compliance the bellows volume, readable from calibrated graphs carried on a curved panel 40. The compliance of the bellows can be varied by moving a spring 50 along guide rails 52, 54 each carrying a compliance scale 116, whereas the weight of the movable plate acting on the bellows can be counterbalanced in the deflated condition of the bellows by adjusting the tension in a spring 76 secured at one end to a bracket and its other end to a pin 84 threadedly engaging a nut 88. Fine piano wires (154, Fig. 3 not shown) fitting snugly around each pleat (150) restrain the pleats from bridging whereas a hole in a plate 162 closely encircles the bellows about its midpoint, the plate being pivoted at the axis of rotation of the movable plates, to reduce bellows sagging. A pair of flat springs 130 each connected at one end to the rear panel 24 of the support case 10 is biased against a rectangular bar 124 provided along the bottom end of the panel 40 and keeps the panel in either a substantially vertical position during operation of the analogue or a substantially horizontal position of storage. A chain 96 prevents accidental over expansion of the bellows 36 and a pin 92 threadedly engaged in a support 90 assures proper positioning of the movable end plate when the bellows are in the deflated condition.

Title: Improvements in or relating to circuit arrangements for address modification in a programme controlled digital computer
Inventor: TRAUBOTH HEINZ
IPC: G06F9/355
Filed: 1963-01-26
Abstract: 975, 751. Digital computers. SIEMENS & HALSKE A.G. Jan. 26, 1963, No. 3351/63. Heading G4A. In an arrangement for modifying the address part of computer instruction words, certain locations in the computer store are provided as index registers and are addressed by an address formed partly from digits contained in the instruction to be modified and partly from digits in an auxiliary register. The arrangement shown in Fig. 2 comprises a computer store AS, an instruction register BR, an instruction counter BZ, an address register AR and an auxiliary register JA-R. An instruction word of 13 decimal digits comprises a 5-digit operation portion 1, a 5-digit address portion 2, a 1-digit 'substitution' portion 3 and a 2-digit additional portion 5 which forms the lower two digits of an index word address in the store; the three higher digits being obtained from the register JA-R. The digit combination 00 in the additional portion 5 indicates that the instruction address is not to be modified. In operation an instruction is extracted from the store AS under the control of the instruction counter BZ, and entered in the instruction register BR. Assuming that the additional portion 5 is not 00, this additional portion and the contents of the register IA-R are transferred to the address register AR to form the address of the index register inthe store AS which is to be employed to modify the whole address part of the instruction register BR, i.e. the portions 2, 3, and 5. The modification operation can thus be performed repeatedly, until the contents of the portion 5 becomes 00. The address now stored in portion 2 of the instruction register is transferred to the address register AR to address the store AS and transfer its contents to the computing unit (not shown). The substitution digit portion 3 controls substitution of the address portion 2, this operation not being described in detail in the Specification; In a modification (Fig. 3 not shown), an auxiliary digit place is provided in the instruction and if this auxiliary place differs in two consecutive instructions, the index address register JA-R is reset to a new value. The arrangement may be applied to multi-address machines if a plurality of registers JA-R are provided.

Patent GB-215427-A (GB)
Title: Improvements relating to earth boring plant
IPC: E21B19/08
Filed: 1923-02-05
Abstract: 215,427. Hild, F. W. Feb. 5, 1923. Hunting switches.-In an earth boring plant, the power taken by the motors is controlled by contacts engaged by the pointer of a wattmeter when the pointer reaches either limit of a predetermined range. The wattmeter has a current coil 318 connected to current transformer 362 in the circuit of the induction motor 341, and a voltage coil 316 connected to a voltage transformer 361 connected across one of the phases of the motor 341. A pointer 323 controlled by the usual rotatable disc 320 and spring 322 moves over a fixed scale 305, which is graduated to indicate the effective weight of the drill, this being proportional to the load on the motor 341. A maximum demand segment 306 mounted on a tubular shaft 307 carries a pointer adapted to indicate the maximum power used. In order that the work of moving the segment 306 may not be directly imposed upon the pointer 323 with consequent inaccuracy of indication, the pointer carries a contact 324 adapted to engage a contact 325 carried by the segment whenever the pointer indicates a load at least equal to the previous maximum. The engagement of these contacts closes a circuit derived from the transformer 361 energizing a coil 331 to withdraw a spring biased brake 334 from a clockwork mechanism 314 which thereupon drives a pinion 337 to turn the segment 306 towards the new maximum until the contacts again separate. A pressure limit dial 309 is carried by a shaft 310 passing through the shaft 307 and engaged by a friction band 307<a> so as normally to move with the segment 306. The maximum power taken by the motor corresponds to the weight of the freely suspended drill, and when the drill touches the bottom of the well the power is diminished in proportion to the pressure of the drill bit on the bottom, thus a scale on the dial 309 indicates this pressure. This dial is set relatively to the segment 306 by means of a knob 311 so that when the pressure reaches a predetermined value the contact 324 on the pointer, which has moved back from its maximum engages a contact 336 on the dial to establish a circuit for operating a control system, causing the motor 341 to take a greater load and thus reducing the pressure on the drill bit. After a cycle of drilling operations the segment 306 is reset to its zero position by a knob 308 on the shaft 307, in which position a contact 327 thereon engages a stationary contact 328 to establish a circuit for returning the control systems to its normal position. Specification 215,694 is referred to.
