Abstract: 876,988. Digital electric calculating-apparatus. PHILIPS ELECTRICAL INDUSTRIES Ltd. Jan. 16, 1958 [Jan. 16, 1957], No. 1560/58. Class 106 (1). A periodically operating digital computer comprises an arithmetic unit subdivided into multi-denominational sections to enable computing operations to be speeded up, every two adjacent sections being separated by a carry storage device, and also comprises a result register the amount in which is transferred, e.g. to a main or auxiliary memory, after receipt of a signal indicating that none of the storage devices contains a carry. In the parallel adder shown in Fig. 3, registers 1, 2 store in members 4 0  ... 4 5  and 5 0  . . . 5 5 , the digits of two numbers to be added. The associated logical adders 6 0  ... 6 5  are divided into sections 3 1 , 3 2  ... separated by carry storage devices 9 1 , 9 2  ... The adders receive digit and carry inputs and supply outputs via gate members 7 0  ... 7 5  to register 1. Fig. 4 shows a single denomination in which register members 4i, 5i are Eccles-Jordan circuits storing binary digits xi, yi, and the adder 6i and member 7i comprise networks of AND gates A, OR gates 0 and inverters I. The adder 6i receives the digits xi, yi in direct and complementary form and a carry digit C i - 1 ,  i  and provides a further carry digit C i ,  i +   1  and sum digit z which is passed through 7i under control of pulses on conductor 8. These pulses control also the setting of the carry storage devices which may comprise further Eccles-Jordan circuits. The lower limit to the repetition period of the control pulses for a given number of denominations in a section, is given in the Specification. A multiple AND gate (not shown) tests whether any carries are present in the storage devices 9 1 , 9 2  ... and during "afterstrokes" of the computer for dealing with the stored carries register 2 is either zeroized or separated from the adders by further gates (not shown). The sections 3 1 , 3 2  ... may be divided into sub-sections as described in Specification 876,989. The register 1 may have provision for shift. Reference is made to performing subtraction, multiplication and division.

Title: Ornamental stitch sewing machine
IPC: D05B19/00
Filed: 1940-02-01
Abstract: 534,345. Sewing-machines. SINGER MANUFACTURING CO. Feb. 1, 1940, No. 1952. Convention date, April 1, 1939. [Class 112] In a machine with a rotary eccentric producing lateral vibrations of the needle, the needle makes a plurality of reciprocations during each lateral movement. Faggoting and other figure stitching is produced in the machine described, in which the needle bar is vibrated laterally by an eccentric making one revolution for six descents of the needle and the feed varying and reversing gear is actuated by another eccentric which makes one revolution for three needle descents. The figures are varied by altering the amplitude of the lateral needle vibration and of the variations in the feed by altering the throw of the eccentrics and the timing relations between the two variable eccentrics and between the eccentrics and the descents of the needle. The feed variation is produced by moving the connection between a link and an oscillating arcuate slideway and the movement is such that two forward feeds are followed by one backward feed. Fig. 4 shows the assembly of the two controlling eccentrics. The shaft 23 is driven by a six to one gear 26, 27 from the needle-driving shaft 5. The lateral vibration eccentric 18 is carried by a disc 21 secured to the shaft 23 and is adjusted against a spring by means of a coned pin 33. The feed controlling eccentric 86 is fast on a shaft 88 which carries a bush 90 upon which the wheel 94 of a three-to-one gear is secured. The bush 90 and shaft 88 are coupled by means of two discs 97, 100, the former having a series of spaced holes 98 and the latter a pin 99 which enters one of the holes. The disc 100 is splined to the shaft 88 and can be moved axially against a spring 104 to move the pin 99 from one to another of the holes.

Abstract: 764,695. Printing-telegraph transmitters. SIEMENS & HALSKE AKT.-GES. Jan. 22, 1954 [Jan. 23, 1953], No. 2034/54. Class 40 (3). In teleprinter apparatus in which a first unit, for initiating the transmission of signals, includes a keyboard, an electromagnet and an operatively associated armature is employed in conjunction with a second unit comprising a transmitter for sending the said signals, a receiver to print the message, which is not provided with a keyboard (or has a keyboard which is not utilized) and a sending distributer, the armature is arranged to be actuated in dependence on the condition of readiness of the transmitter and carries a plurality of contacts arranged to be selectively actuated under control of the keys of the keyboard and electrically connected to the sending distributer, and a transmitterrelease arrangement, incorporated in the first unit, is operated by the movement of the armature. The operation of a key 1 selectively moves bars 2 coupled by levers 3 to pivoted arms 8 carrying abutments 5 associated with respective contact pairs 6 carried on the armature 10 of an electromagnet 7 energized during the stop condition imposed by the distributer of the second unit. In the stop condition, the armature 10 is retained in the attracted position by the notched end 11b of a pivoted latch 11. On the actuation of a key 1, the depression of a universal bar 14 rocks a lever 15 coupled to a lever 16 rocking an arm 17 carrying a pivoted interponent 20 having an arm 20a which engages an arm 11a to lift the latch 11 so that the armature 10 is rotated clockwise by the spring 18 and contacts 6 are opened by the abutments 5 of those levers 8 which have been rocked clockwise by the movement of the bars 2. The contacts 6 are connected to the distributer which is started into operation by the closure of contacts 12 by the movement of the armature 10. During the initial movement of the armature 10, a latch member 21 is rocked counterclockwise so that the end of its upper arm engages under a projection 20c of the interponent 20 and in subsequent movement the armature engages an abutment 20b so that the member 20 is rocked counterclockwise to be latched by the member 21. A plate 23 engaged by projections 10a, 10b of the armature has a knife-edge portion 23c locking the ends 8a of the levers 8 in their respective upper and lower positions. The plate 23 is not attached to the armature 10 and is connected by a spring 24 to a fixed post 25. At the end of a signal the magnet 7 is energized in response to the stop impulse and the latch 11 operates to retain the armature 10 in its attracted position. The final movement of the armature engages projection 21a to disengage the latch 21 from the interponent 20, but the end 20a is unable to engage in the notch in the arm 11a of the latch 11 until the lever 17 is returned to its normal position on the release of the key 1.
