Filed: 1940-03-12
Abstract: 536,789. Window-shutters. ROBERTS, A. March 12, 1940, No. 4590. [Class 20 (iii)] Shuttering for masking roof lights consists of a series of shutters 3, 4 of corrugated sheet metal hinged together at 6 in separate pairs, one end of each pair being pivotally anchored at a, while the other end is slidable towards the anchored end of the next shutter, so that each pair of shutters is spread to a very obtuse angular formation as shown in full lines. In the opened position, the shutters are at an acute angle as shown in dotted lines. Each shutter is mounted on angle irons 5, one of each pair being pivoted at 8 to short brackets 7 carrying rollers 10 running on two horizontal tracks 12, one track being arranged at the higher level on the sloping roof, and the other at the lower level, the tracks being formed by angle irons carried by cleats from the roof purlins. The lower track is adapted to take the thrust of additional roller, and thus to support the weight of the shutters. The shutters are opened and closed by parallel rods 15, 16, the outer rod 15 being secured to bosses 18 of the brackets 7, and the rods being connected at their ends by chains running over sprockets (not shown) driven by gearing from electric motors. The apex edges 3a, 4a of each pair overlap in the closed position as shown, and to enable the edges 3b, 4b to overlap, the anchored edges 3b are kept slightly raised by the action of springs on bell cranks 20 to which the edges are pivoted at a. When the shutters are spread, brackets .7 contact with loose bosses 23 which, by pressure on links 22, rotate the bell cranks against the spring pressure and lower the edges 3b of the sHutters on to the corresponding edges 4b of the adjacent shutters.

Abstract: 1365069 Automatic exchange systems INTERNATIONAL COMPUTERS Ltd 17 Feb 1972 [17 Feb 1971] 4800/71 Heading H4K An automatic dialling system for connecting a central data processing unit to a remote terminal by way of an automatic telephone communication system which includes a translator for converting binary signals from the data processing unit into decimal units and a transmit unit for producing pulse groups from the decimal units and for applying the pulse groups to the automatic telephone system to cause the latter to operate the remote terminal. As described a control unit 11 receives the number of the required remote terminal 26-28 from the data processing unit in binary form over a line 21, each digit being fed separately when a call up signal is sent in the reverse direction over a line 22. The control unit converts the binary signals into decimal form and stores a number of pulses corresponding to the digit in a shift register 12. These pulses are then fed to transmit unit 18 at the required rate over line 14, the mark to space ratio of the pulses to be transmitted being controlled by a binary signal supplied from the control unit 11 to the transmit circuit 18 over line 16. At the end of each digit of the number a control signal in binary form is fed from control unit 11 to transmit unit 18 over line 17 thereby to ensure the correct interdigital pause. The pulse trains are sent over a transmission line 23 to a standard telephone exchange which completes the connection to the required remote terminal in any known manner.

Title: Improvements in control systems for electrical range units and the like
IPC: H05B1/02
Filed: 1939-02-15
Abstract: 525,089. Thermal switches; actuation of switches. PROCTOR & SCHWARTZ, Inc. Feb. 15, 1939, No. 4993. Convention date, Feb. 21, 1938. [Class 38 (v)] [Also in Group XXXV] Electric hot plates and like cooking units are associated with switching means whereby they may be operated at two or more than two different temperatures and, at one or more of these temperature settings, flash heated by abnormal energization which is automatically removed when the selected temperature is reached. As shown in Fig. 1, a series-parallel switch 14 is maintained for flash heating (parallel circuit) in the position shown, by a spring 22. At either of two temperatures determined by the setting of a manual switch 3 which applies half or full voltage to the heating units 1, a thermal ' element 25, heated by an element 34 having heating g characteristics similar to the heating unit 1. actuates the spring 22 to cause the switch 14 to take up and hold the normal heating (series) position. The temperature setting of the change is determined by a cam 32 which through a rod 30 and thermal element 29 correcting for ambient temperatures, positions the element 25 in relation to the spring. A continuous range of temperature adjustment is provided by the arrangement shown in Fig. 2, wherein two thermal elements 38, 39 are heated in common by an element 46 and arranged so that the element 38 is contacted by an arm 37 just before the element 39 as the control knob 44 is screwed down. The temperature of the hot plate is determined by the action of the element 37 and the flash heating connection is established by a relay 48 under the control of the element 39; in the lowest temperature setting flash heating is not established. In these arrangements a single heating element 34, 46 is in series with one of the sections of the unit 1 supplied. Fig. 4 shows an arrangement in which a thermal element 62 operating the change-over switch 58 is heated by an element 59 in the " high" setting of switch 63, which element subsequently suffices to maintain the normal condition of the switch 58, but an element 60 is added in the " low " setting and a further element 61 is energized when the change-over takes place to ensure maintenance of the normal condition. A modified arrangement of switches using a similar arrangement of auxiliary heating elements, is described. In a further arrangement providing flash heating only in a high temperature setting of a "highlow" control switch, a relay controlling the flashing of the plate heaters is energized through an auxiliary switch operated by a cam coupled to the control switch. The auxiliary heaters are preferably located remote from the hot plate but the thermal elements may be operated by heat generated by the hot plate.
