Title: Apparatus for packing objects into a box
IPC: B65B57/14
Filed: 1966-08-02
Abstract: 1,113,071. Packaging-machines; endless conveyers. J. J. SHUTTLEWORTH. 2 Aug., 1966 [16 Dec., 1965], No. 34585/66. Headings B8A and B8C. Objects such as cans are fed by a conveyer 200, Fig. 4, on to a platform 205, above which is positioned a number of vacuum cups 300 for engaging the individual objects, whereupon the platform 205 is moved from beneath the vacuum cups 300, which are then moved vertically downwards to place the articles in a box 75. As described, a box is fed by a conveyer 40 on to a horizontal support 51, along which it is intermittently moved to beneath the platform 205 by bars 50 attached to an endless chain 47, which is driven via a chain 117 (Fig. 12) by an hydraulic cylinder 115. The chain 117 is moved on the return stroke only of the piston 116, movement during the forward stroke being prevented by a one-way clutch 122. The amount of movement of the chain 47 during each return stroke of the piston 116 is controlled by a dog 160 (Fig. 13), attached to the chain 117, which causes a stop-member 146 to move in front of one of the bars 50 thereby stopping the chain 47. As the box is moved along the surface 51, the crease of the leading flap 66 is broken by a flap breaker (56) (Fig. 5, not shown) and the two opposite side-flaps, having previously been held open by a U-shaped member 55, are guided between a pair of parallel members 80 and 81. The cans moving on the conveyer 200 are guided into parallel lines by guide elements 17, at the end of which are pivotally connected doors (222) (Fig. 11, not shown), which are hydraulically pivoted when the cans have accumulated on the platform 205 to prevent the forward movement of further cans on the conveyer. A limit switch 362 is closed when a pattern of cans has formed on the platform 205 and limit switches 600 and 601 closed when a box is in the loading position and another box is moving into the conveyer 41, whereupon a cam-shaft (536) (Fig. 15, not shown) is rotated to operate the sequence of operations by means of valves. When glass containers are packed, limit switches may be used to stop the apparatus if the downward stroke of the vacuum head 16 is incomplete. When more than one layer is packed, vacuum cups (550) (Fig. 16, not shown) mounted on extensions (551) may be used. Cantilever springs (800) (Fig. 19, not shown) may alternatively be used to fold down the leading flap (66<SP>1</SP>).

Title: An improved polyphase generator of the thermionic type
IPC: G01R1/28
Filed: 1947-12-30
Abstract: 653,815. Valve generating circuits. TESLA, ELECTRICAL & RADIO INDUSTRY, NATIONAL CORPORATION. Dec. 30, 1947, No. 34655. Convention date, Nov. 11, 1946. [Class 40 (vi)] In a resistance-capacity oscillator of the Wien bridge type additional resistances and capacities connected to the feed-back network enable two outputs to be obtained which are in a constant amplitude ratio and have a phase difference of 90 degrees independent of the frequency of oscillation. The oscillator comprises an amplifier 1, Fig. 3, of zero phase-shift across the output of which is connected a network comprising resistances 2, 4 and capacities 3, 5, with the input taken across the series elements 2, 3. Resistance 6 and capacity 7 are also connected in series across the amplifier output, all resistances and condensers being of like value ; outputs differing in phase by 90 degrees are obtained from the terminals 8, 9 and 8, 10 respectively. The amplitudes may be equalized by connecting resistance 6 to a tap on a loading resistance 13 utilized to render more constant the impedance into which the amplifier works, or by replacing the condenser 7 by two in series, Fig. 4 (not shown), with the common point as terminal 9. The arrangement may also be modified to use condensers as the elements 2, 6, the elements 3, 7 comprising resistances. In another embodiment, Fig. 5 (not shown), in which the loading on the amplifier is maintained constant, parallel-connected elements correspond. ing to the elements 4, 5 are introduced in series with the resistance 6, while in a further embodiment, Fig. 6 (not shown), the resistance 6 is returned to the input of the amplifier instead of the output. A complete A.F. generator for measurement purposes comprises an oscillator of the latter type, Fig. 7, the potentials across elements 2, 7 being applied over amplifiers II, III, to mutually perpendicular points on a circular potentiometer P2 from the slider of which potentials of continuously-variable phase but fixed amplitude are derived. Two outputs respectively of variable and fixed phase are obtained across further amplifiers IV, V, and potentiometers P3, P4 which provide for amplitude adjustment.

Abstract: 1,040,999. Electrophonic musical instruments. W. E. ROBERTS. Aug. 10, 1965 [Aug. 25, 1964], No. 34781/64. Heading G5J. An ultrasonic frequency is sampled at such a frequency that the sampling frequency or a multiple thereof differs from the ultrasonic frequency by the required audio frequency. A crystal controlled oscillator XT, Fig. 1, feeds a sampling unit N which also receives pulses from a crystal-controlled oscillator Xs, the output being fed through an amplifier A to a loud-speaker L. Seven ultrasonic " tone " generators T1 ... T7, Fig. 2 (not shown), together with two sets of ware-sampling units N1 ... N12 and N1<1>... N12<1> enable all the notes of seven octaves to be generated. In an organ, Fig. 3 (not shown), 20 sine wave oscillators H feed ultrasonic frequencies through a coupling unit comprising adding amplifiers with feedback resistor networks Rm<n> and associated switches Sm<n>. When a D.C. voltage is applied to a switch the corresponding frequency passes to an adding unit A1 . . . A7. The outputs from these units are fed over keying switches K11 &c. controlled by the keyboard. The outputs from the keying switches are connected to wave sampling units N1, N1<1> &c. feeding an audio adding circuit M. The key switches are arranged to minimize " key click," by the use of a block B, Fig. 5 (not shown), of soft rubber, with a coating of conductive material Z which is pressed against contact wires W1, W2 as the block B is pushed down. Small low-frequency variations in pitch may be introduced, Fig. 1, by the use of a lowfrequency generator 104 which is added to the D.C. bias across a voltage-sensitive backbiased P-N junction 103.

Title: Control apparatus for a digital electronic computer
Inventor: SCOTT-KERR ROBERT JAMES
IPC: G06F13/26
Filed: 1964-08-28
Abstract: 1,113,361. Digital computers; priority interruption. ENGLISH ELECTRIC COMPUTERS Ltd. 27 Aug., 1965 [28 Aug., 1964], No. 35317/ 64. Heading G4A. In control apparatus having a plurality of storage means for receiving interrupt signals arising from a process or apparatus controlled by a digital computer, interrupt signals of different priority are routed to different storage means each of which is assigned a different degree of priority and only the interrupt signal of highest priority is transmitted to the computer. As shown (Fig. 1), 128 lines on which the different interrupt signals may be received are arranged in groups of 16 (two of which 3, 4, are shown) each group of 16 being connected to a separate module of 16 storage means (two of which A and B are shown). The 16 storage means in each module are arranged in order of priority as are also the modules themselves. On receiving an interrupt signal, say on one of the lines into module B, and assuming module A is not issuing an inhibit signal along line 7 and no higher priority signal is being received by module B, an interrupt signal is issued to the computer 16 by way of lines 5 and 6, a staticiser 25 and line 26. At the same time signals identifying the interrupting module and the storage means within the module are carried by lines or channels 8, 10 and 9, 11 respectively to encoder 12 for encoding the information into binary form. On receiving a read signal from the computer by way of line 19, decoder 18 and line 14, the encoder 12 transmits the signal identification information along channel 13 to the computer (line 17 is for parity). At the same time a signal on line 29 resets staticizer 25 ready to receive a further interrupt signal. In order to cancel the setting of its storage means after an interrupt signal has been dealt with by the computer, signals identifying the storage means concerned are issued from decoder 31 in response to signals from the computer along channels 33 and 34. Simulation of the arrival of an interrupt signal may be achieved by signals issued along channels 35 and 33 in response to coded signals received from the computer or from a manual control panel 36. The setting of the storage means in any one of the modules may be interrogated in response to coded request signals from the computer by signals in channel 39, the requested data being transmitted to the computer along channel 40. All the modules may be inhibited from responding to interrupt signals by energizing a line 41. Signals in channel 45 from manual control panel 36 cause the pattern of interrupt signals stored by any chosen module to be displayed. Effective priority level of interrupt signals may be varied by having certain input lines connected to more than one storage means and selectively inhibiting these storage means as desired. Fig. 2 (not shown) illustrates the logic circuitry within the modules using AND- gates, OR-gates, bi-stable staticizers (constituting said storage means) and inverters.
