Abstract: 311,406. Cuvelier, P. May 12, 1928, [Convention date]. Void [Published under Sect. 91 of the Acts]. Stationary-mould machines; shaking and jigging machines ; tamping-machines ; feeding.- Material is conveyed in one or more layers from a hopper K, Fig. 2, to a mould B by a reciprocating charger k<1> fitted with wood or metal cores k<3> supported by blade springs k<4> and furnished with pivoted doors k<7> retained by hooks engaging a locking-bar k<5>. As the charger passes over the mould, the bar k<5> is curved back by an abutment k<13> to release the doors which fall open to discharge the material. On the return movement, an incline k<9> recloses the doors which are re-locked bv reverse movement of the bar k<5> bv a second abutment. As shown, the ram D, carrying an interchangeable die F, is suspended by a hook u<2> upon a screw p<16> working in a nut p<16> operable through bevel gear p<12> from pulleys controlled bv a member P. The catch u<2> is released by hand to allow the stamp to drop on to the material after which the mould is vibrated through a frame I having depending rods i<1> furnished with adjustable stops adapted to engage frames c<2> adapted to be coupled to the mould. Pressure may be applied through the screw. The ram is held down by detents L<6>, Fig. 5, forced outwardly by a wedge L<4> to engage teeth L<7> on the press guides G whilst the mould is raised through the frame I to deliver the moulded article. Various forms of detent device and driving-gear are described. Fig. 3 shows a modified press which is fluid-operated.

Title: Improvements in or relating to tapping machines
IPC: B23G1/16
Filed: 1958-05-06
Abstract: 915,286. Screw-cutting. BRISTOL REPETITION Ltd., and ARENGO, C. G. April 27, 1959 [May 6, 1958], No. 14463/58. Class 83 (3). In a screwing-machine wherein the tool is advanced quickly to the work and the feed is then controlled, the drive-spindle and a coaxial sleeve are moved axially, the spindle is then rotated and the sleeve is held against rotation and further axial movement of the spindle is caused by a nut and screw on the spindle and sleeve, having the pitch of the thread to be cut. A drive-spindle 24 carrying a screw 23 is screwed into a rotatable and axially-slidable sleeve 15, and is splined in a pinion 27 rotated from an electric motor 13 through a geartrain 28. The end 26 of the spindle 24 is rotatable in a bridge 31 connected to a rod 29 which moves axially with the spindle. The sleeve 15 has an-annular groove 20 to engage rollers 19 on the forked-end 18 of a lever 16. The lever pivots at 17 and is spring-urged in the upward direction so that when the lever is depressed by hand, the sleeve 15, spindle 24 and rod 29 move downwardly until the bevelled face 35 on the sleeve 15 abuts a corresponding face on a bush 34 secured in a plate 32 which is non-rotatable but axially resiliently connected to a fixed bush 14 in the housing 11, due to a spring 33. In operation, as the tap or die connected to the shaft 24 at 25 is moved up to the work by the lever 16, a pin 36 in the bridge 31 actuates a switch 37 to start the motor 13 and the sleeve 15 and spindle 24 rotate. When the face 35 on the sleeve engages the bush 34, rotation of the sleeve ceases and the screw 23 on the spindle 24 moves in the nut 22, thus controlling the feed of the tap or die. A further slight pressure on the sleeve 15 when it engages the bush 34 compresses the spring 33 and a recess 38 in the lever 16 engages a pawl 39 to rock it about a pivot 40 against a spring 41 and cause it to lock the lever 16 and sleeve 15. At the end of the screwing operation a nut 42 on the rod 29 actuates a switch 43 which reverses the rotation of the motor, and the spindle 24 and rod 29 move upwardly until a cam 44 on the rod 29 releases the pawl 39 from engagement with the lever 16 and the spring- urged lever 16 moves the spindle 24, rod 29, and sleeve quickly to the starting position, and in so doing a switch 46 is actuated by the pin 36 to stop the motor 13. The switches 37, 46 operate only in one direction. The positions of the nut 42 and the cam 44 are adjustable.

Bird swing fault present in the container will reflect or refract the light beam into elongated detection units 60 or (62). The output signal of the detection units is fed into a gating system relay Fig.6 (not shown) with the signals from a pair of photo-cells (42), (44) arranged opposite a pair of light sources (48), (50). The gating system relay eliminates false signals due to the leading or trailing edges of the container 14 and only activates a solenoid valve 54, controlling a compressed air supply, when a bottle is present and a fault is detected. The detection units 60, (62) consist of a body plate (88), Fig.5 (not shown) provided with an elongated channel (90) which communicates with an angled elongated slot 84 or 86.

Heading B8D. The end wall 9, or lid, of a container 7 is provided, adjacent a shoulder 27, with a circular line of weakness 35 interrupted by a stop 37, and a peripherally extending channel 19 in which is retained a flange 45 of an opening device 13, the handle 41 of which is formed with a central rib 51, one end of which provides camming means 53. To open the container, the member 45 is positioned adjacent the stop 37 and the handle 41 is raised at its inner end. The device bends about lines 65, projecting the sharp end 54 of the camming means 53 against or adjacent the line of weakness, and puncturing the end wall. When the handle is vertical, the camming means 53 rests on the bent down portion of the end wall. On sliding the device around the container the central portion of the end wall is removed by tearing the line of weakness. Alternatively, Figs. 1-6 (not shown) accompanying Provisional Specification 53051/65, the device handle (280) may extend tangentially inside the container rim. Again, Figs. 1-7 (not shown) accompanying Provisional Specification 31910/65, the end wall is provided with spaced parallel shoulders (102) defining a raised portion (149) along a diameter of the end wall (88), along which a similar opening device (132) slides to bend open a U-shaped portion (94) defined in the raised portion by a line of weakness (110). An alternative embodiment, Figs. 1-4 (not shown), accompanying Provisional Specification 43060/65, also relates to a similar opening device for a U-shaped portion. The lines of weakness may be formed alternatively or additionally on the inside end wall surface. The end wall and slider may be formed of tinplate, aluminium or plastics. The opening device may be applied to any wall of the container.

Abstract: 1427911 Charge transfer delay circuits ITT INDUSTRIES Inc 4 April 1974 [6 April 1973] 14982/74 Heading H3U A bucket brigade circuit comprising transistors T n-1 , T n , T n+1 , T n+2  &c. and capacitors C n-1 , C n , C n+1  &c. has an amplifier T a , T b  with its input connected to one of the nodes U n  and its output capacitively connected to the same node to provide compensation for frequency dependent attenuation. The amplifier output is connected to the node via series connected capacitors C1, C2, the junction point of which, U 2 , is connected to a point of constant potential via transistor T s  controlled by an auxiliary clock signal which turns T s  off after T n  has been turned off, but before T n+1  has been turned on. Optimum compensation is stated to be attained when α(C2)/(C n  + C 2 ) = (d max )/(2 - d max ) where α = amplifier gain and d max  = attenuation without compensation. If a variable clock frequency is used, the gain of the amplifier is regulated for optimum compensation. When clocks # 2 , #<SP>1</SP> 2  are effective to turn T n  and T s  on, C n  is increased to C n +C 2 . After T n  and T s  are turned off # 1  turns T n+1  on, the charge from C n +C 2  is transferred to C n+1 , and the potential at U n  rises. This rise is inverted by the amplifier and is fed back to produce an effective increased capacitance
