Title: Improved information storage system
IPC: G11B5/596
Filed: 1962-10-10
Abstract: 985, 064. Digital data storage;transducer positioning. INTERNATIONAL BUSINESS MACHINES CORPORATION. Oct. 10, 1962 [Oct. 10, 1961], No. 38431/62. Headings G4C and G5R. A recording medium such as a disc 10 is divided into storage areas 12 by reference patterns 13 which define storage tracks on the medium and are used in the fine positioning of the transducer. In Fig. 1, housing 14 contains two transducers spaced three tracks apart, but the same transducer is always used in the fine positioning. A transducer 16 produces timing signals from a track on the disc,and a second transducer (Fig. 3, not shown) associated with another disc produces signals indicating that reference patterns are passing the housing 14. The timing signals define A and B times (Fig. 2). A reference pattern is shown which, if transducer 20 were at the centre of track 2,would generate equal amplitude signals during A and B times. Signals received during these respective times are compared while a reference pattern is passing transducer 20,the comparison being used to generate error signals restoring the transducer to the centre of the required track. Data signals, shown on either side of the reference pattern, are recorded at an angle to the direction of motion of the medium, the angles in adjacent tracks being measured in different senses to reduce interference. Light reflective reference patterns may be used, or the invention may be applied to multitrack magnetic tape.

Components having an elongated stem of magnetizable material and an enlarged head at one end of the stem are removed from apertures in a carrier by means of apparatus comprising an electromagnet which lifts the components so that their heads enter slots in a first member along which they are moved until the stems of the components enter slots in a second member. As shown in the exploded view of the apparatus, Fig. 2, semi-conductor diode housing assemblies 5, each comprising a dumet wire sealed into one end of a glass or metal tube, are brought up in a carrier 1 having an array of apertures 4 through which the wires of the components 5 are threaded. The carrier is guided by end members 25 to a position below a first member 10 the lower face of which is provided with slots 11 aligned with the rows of apertures in the carrier. An electromagnet 30 positioned above member 10 is energized and lifts the components 5 so that their heads enter the slots 11 while their stems still extend into the apertures 4 in the carrier 1. The carrier 1 is then moved so that the heads of the components slide along the slots 11 until the stems of the components enter slots 15 in a second member 12. The electromagnet 30 is then deenergized and the carrier 1 is removed downwardly, the components being supported by member 12 since the slots 15 are narrower than the heads of the components 5. The member 12 is mounted at an angle to the horizontal so that the released components slide under gravity until they enter slots 27 in a second carrier 26 which is removed from the machine when filled.

Title: Intruder alarms
IPC: G08B13/189
Filed: 1962-10-18
Abstract: 972, 171. Electric bridge circuits. UNITED STATES ATOMIC ENERGY COMMISSION. Oct. 18, 1962 [Nov. 22, 1961], No. 39516/62. Heading G1U. [Also in Division G4] An intruder alarm system (for use in an enclosure) includes a single source of light energy 1 (Fig. 1) and several pairs of light sensitive detectors 2, connected in a bridge circuit energized from a D.C. source such that the individual members of each pair are in opposite arms of the bridge. An alarm is connected across the bridge to respond to out of balance conditions. The system is such that the output voltage is independent of variations in the light or voltage sources, but is very sensitive to interruption or variation in light intensity at one pair of detectors. In the first described embodiment (Fig. 2) the D.C. supply is derived by rectifying and smoothing an A.C. supply 10, 11, a suitable voltage being tapped from the potentiometer 22. The supply circuit includes a relay coil 24 which actuates the contacts 25 and hence an indicator 27 in the event of a supply failure. The bridge may be composed of pairs of photoresistors or cadmium sulphide cells 30, 31 and 32, 33 and any out of balance condition, caused by interference with the light pattern at one of the pairs, actuates the relay coil 34 and hence the contacts 37 and the alarm 38. Any failure of the light source affects all pairs equally and so the intruder alarm does not operate, but the increased impedance of the bridge can be utilized to operate relay 24, so that this will indicate failure of the bridge supply sources. If the alarm actuating source 26 is a battery it can be connected into the circuit across the leads 23, 29 so as to act as an auxiliary supply in the event of a mains voltage failure. A second embodiment (Fig. 3) is battery powered and is arranged to extend the battery life by using the battery 40 to energize a free running multivibrator 45 which pulses the light source 47 intermittently. The bridge and alarm circuits are also energized from the same source.

Title: Improvements in or relating to card and sheet feeding apparatus
Inventor: HIRST PETER DAVID
IPC: G06K13/103
Filed: 1957-12-23
Abstract: 901,456. Feeding sheets. INTERNATIONAL COMPUTERS & TABULATORS Ltd. Nov. 14, 1958 [Dec. 23, 1957], No. 39904/57. Class 100 (1). [Also in Group XXX] Sheets 1 (Fig. 1) are fed one-by-one from hopper 5 through throat 6 by reciprocating separator 8 which is carried by slider 14, operated by crank 22 via arm 21, and pivoted link 18. The separator 8 may comprise a rubber friction pad, but is shown as a knife. The path of the knife 8 is governed by roller 25 which in its forward movement, moves on its first path along surface 27 and past end 28, and then in its backward movement moves on its second path along guide 26. This change to second path which avoids frictional engagement with the sheets, is permitted by the flexible mounting of knife 8 which is connected to the said slider 14 by link 9 and is biased by spring 11. If required, knife 8 may reciprocate without engaging the sheets. This is effected by de-energization of solenoid 29 which allows armature 31 to drop so that, as knife 8 returns along its second path, said armature engages face 35 of link 9 to bend knife 8 anti-clockwise. Thus, roller 24 runs forward beneath guide 26 and the knife reciprocates without feeding any cards. Alternatively, the solenoid may effect the change from the path to another by operating a gate between the two paths. Modification (Fig. 2).-Knife 8 moves leftwards in the first path to feed a sheet from the hopper shown, being carried by reciprocating slide 14, the movement being controlled by the engagement of roller 25 with surface 27. In the extreme left position, the surface 27 forces the knife downwards so that latch 38 is hooked by latch 39, and the knife returns rightwards by its lower second path. Engagement with armature 44 unhooks the two latches, and the knife returns leftwards by its first path, thus feeding a second sheet. If, however, solenoid 42 is de-energized, then armature 44 moves upwards out of the said first path and avoids unhooking the latches. The knife then continues to reciprocate without feeding.

Abstract: 990, 278. Recording-apparatus. P. S. STINTON. Feb. 12, 1963 [Nov. 13, 1961], No. 40600/61. Heading G1J. [Also in Division G2] Recording apparatus comprises means to advance a record medium 13 through a recording station where a trace of a variable quantity is recorded on the medium and a telephone dial mechanism TD whereby electrical pulses produced on dialling a number produce a record on the record medium of the number dialled. A recording camera (not shown) has a motor 1 which feeds light sensitive paper strip past a recording position at which a variable trace 14 representing, for example, a cardiographic record is recorded. A relay 10 carrying a mirror, not shown, co-operating with a light source causes a notch to be formed on a continuous trace 15 on the record strip when energized. Dialling a number closes contact TC1 causing energization of relay RI and closure of contacts R1a and R1b. Contacts TC2 make and break a number of times depending on the number dialled, thus initiating pulses which through energization of relay 10 cause marking of the paper strip, e.g. with a series of dashes corresponding to the number dialled.
