Title: Apparatus for producing waste and reserve windings on bobbin tubes on winding machines
IPC: G01R13/20
Filed: 1975-08-22
Abstract: 1472730 Producing waste and reserve windings MASCHINENFABRIK RIETER AG 22 Aug 1975 [12 Sept 1974] 34918/75 Heading DIJ  To provide a waste bunch and thread reserve winding on a bobbin tube two toothed thread guide combs are provided, one after the other in the direction of axial flow of the thread, at least one of the combs being capable of being raised and lowered at at least one frequency corresponding to the speed of rotation of the bobbin tube. In Fig. 1 it is the comb 4 that moves up and down, the comb 9 remaining stationary. Whilst the thread 3 is on a flat part 12 of the combs a waste winding 21 is formed on the bobbin 2. When the comb 4 moves down, the thread 2 is released from the vertical face of the first tooth of the comb 4 and abuts the vertical face of the first tooth 5 on the comb 9. When the comb 4 rises, the sloping surface of the first tooth on the comb 4 lifts the thread 3 and raises it up and off the vertical surface of the first tooth of the comb 5. The yarn then slips down onto the vertical face of the second tooth on the comb 4 and so on. The yarn thus progresses along the bobbin 2 in a step-by-step manner to form a transfer tail on the bobbin 2. Comb 4 is raised and lowered by at least twice the tooth height. Alternatively the comb 9 could also be provided with an up and down movement operating at the same frequency as comb 4, but with a phase shift. The up and down movement of the comb or combs can be initiated by a contact sensor arm 5 which is depressed by the thread 3, when tensioned, whilst the thread 3 is in the flat zone 12, the arm 5 being part of a switch 6 which acts through a timing delay 7. The switch 6 controls a lift drive mechanism 8 fed by a power source operating at the same frequency as synchronous motor (not shown) driving a friction roller for the bobbin 2. In a modified embodiment each comb 4, 9 is provided with two toothed sections and two untoothed sections, Figs. 2 and 3 (not shown). In a further embodiment each comb 4, 9 is extended away from the flat part 12 as a mirror image of itself for simultaneously forming a waste bunch and two reserve windings on double bobbins on a common tube. In a further embodiment, Fig. 5 (not shown) the combs are interconnected at their base and rock about an axis extending along the interconnected bases. In this embodiment square-shaped teeth are formed on the combs.

Title: Search memory using longitudinal steering fields
IPC: G11C15/02
Filed: 1961-09-28
Abstract: 1,007,222. Circuits employing bi-stable magnetic elements. SPERRY RAND CORPORATION. Sept. 28, 1961 [Jan. 17, 1961], No. 34996/61. Heading H3B. An element (Fig. 1) of a thin film matrix consists of two thin film ferro-magnetic members 1, 3, each with a preferred magnetic direction, these preferred directions being at right angles so that the field produced by the upper member 1 representing stored binary bits is able to rotate the direction of magnetisation of the lower, which is of lower coercivity away from its preferred direction. In operation, member 1 is magnetized in the direction 4 or 6 according as a " 0 " or a " 1 " is stored. To interrogate the device for the presence of a " 1 " a current flows in the direction 12 in an interrogation conductor 7. If a " 1 " is already stored in film 1, the total field acting on film 3 is doubled but since the latter is already saturated, this has no effect and the field in the film remains aligned with that in film 1. If a " 0 " is stored, the interrogation and storage fields cancel each other at film 3. Consequently, the magnetic field of film 3 rotates into its preferred direction. A steering field consisting of a steady current in a conductor 5 is provided to ensure that the field in the film always takes up a particular one of the two possible directions. The non-agreement is detected by a sensing conductor 9 which has a pulse induced in it when the interrogation commences and another when it ceases. The presence of these pulses is an indication of non- agreement between the interrogating and the stored signal. Similarly, by passing an interrogation signal in the direction of arrows 10 in conductor 7 the presence of a stored " 0 " is detected. Again an output appears only if the interrogation and stored signals disagree. Matrix (Fig. 4).-Each of the vertical columns of the arrangement shown stores a binary word one digit of which is in each of the elements in the column. All the elements in a particular row are tested simultaneously by a signal applied to the common interrogation line K. Disagreement between the interrogation signal and the stored signal in any of the elements produces an output on a common sense line J, J + 1, J + 2 associated with the column in which that element appears. Similarly line K + 1 tests the next row, K + 2 the next, and so on.

Title: Vehicle heating system
IPC: B60H1/03
Filed: 1965-08-17
Abstract: 1,120,118. Heating and ventilating vehicles. STEWART-WARNER CORP. 17 Aug., 1965 [17 Aug., 1964; 9 March, 1965], No. 35228/65. Heading F4V. [Also in Divisions G1 and H1] A heating system for the cab of a motor vehicle includes a blower 12 for constantly forcing air through air passages to the cab 51, heat exchangers 14, 16 to transfer heat from the engine to the air in the air passages, means such as the valves 28, 29, 42 for preventing air passing to the cab from being heated by the heat exchangers, and thermostatic means responsive to the temperature of the air in or passing to the cab for cyclically actuating and de-actuating the first-mentioned means to modulate the air temperature about a selected valve by causing the cab alternately to receive air heated in the heatexchangers and air not heated in the heat exchangers. As shown the air is heated in the heat exchangers 14, 16 by passing over the exhaust pipes 18, 20 of the vehicle engine, and the valves 28, 29, 42 are operable to prevent the air passing through the heat exchangers to the cab and direct it through an unheated by-pass 40. The air may be further heated in cold weather or when the vehicle is descending a long incline by a booster heater 46 with a burner 54 and spark igniter and the thermostatic controls supply heated and unheated air to the cab 51 cyclically through passages 50 to modulate the temperature about a desired average. A thermostat 58 in a plenum chamber 48 controls the operation of the system through cams operating switches, the temperatures at which the switches are operated being manually selectable by rotating a bimetallic element by a Bowden wire from the cab. The blower 12 may be driven from the vehicle engine or driven by a separate electric motor. Instead of directing the air through an unheated by-pass when heating is not required, the exhaust gases may be bypassed around the heat exchangers 14, 16 (Fig. 5, not shown). The thermostat 58 comprises a bi-metallic spiral the anchorage of which may be adjusted from the cab by a Bowden wire mechanism acting through a segmental rack and a pinion (Figs. 19-21, not shown) (see Divisions G1 and H1).
