Title: Improvements in sash windows
IPC: E05F11/00
Filed: 1946-05-31
Abstract: 612,758. Sliding window holders; catches. HILL, T. D. May 31, 1946, No. 16655. Addition to 574,474. [Class 44] In means for adjustably supporting a sliding window sash of the kind described in the parent Specification, the rack 12, has ratchet teeth, the latch member 5 is so'mounted that when moving vertically in the aperture in the latch plate 1 it works about a bearing 9 well in the rear of the latch plate so that the displacement which enables it to engage and disengage from the rack teeth is mainly in a to-and-fro direction, and the surface 5a of the latch member that engages a rack tooth when the sash is being held is horizontal or nearly so, while the opposite surface 5b of the latch is bevelled to co-operate with an edge of the aperture in the latch plate to disengage the latch from the rack teeth. The latch member is preferably formed with a projection 5c on the lower face. The action is as follows : In the static position of Fig. 1, the horizontal under face of the latch rests on the horizontal surface of a rack tooth, so that the sash 3 is reliably supported. To lower the window, the sash is first raised slightly; contact of the latch nose with the sloping surface of the rack tooth moves the latch inwardly and downwardly, causing the projection 5c to engage behind the latch plate as shown in Fig. 2. The sash is then sharply lowered, and the upper flank of the lower rack tooth knocks the latch upwards to the position shown in Fig. 4, when the latch is forced inwardly by contact of its upper surface with the upper bevelled edge of the latch plate aperture. Means for locking the sash in adjusted position comprises a plug 15 rotating in a bore in the housing behind the bearing 9 and having a transverse hole 17 coaxial with the bearing. By rotating the plug, e.g. by means of a key, the latch is prevented from being pushed back far enough to be disengaged from the rack.

Title: Improvements in or relating to control systems for electric motors
IPC: B65H23/198
Filed: 1952-07-04
Abstract: 711,104. Control of several D.C. motors IGRANIC ELECTRIC CO.. Ltd. July 4, 1952 [July 19, 1951], No. 16882/52. Class 38(3) A system for applying stalled tension to a strip of material 10 passing from rolls 11, 12, to a reel 13 comprises a reel motor 19 supplied from generafor 21 which is excited in accordance with the speed of roll motor 14, A generator 17 with a field winding 17a energizes the roll motor. An exciter 27 has a control field winding 33 responsive to the armature current of the motor 19, and is connected in the field circuit of the reel motor in bucking relation to a constant source 15, so that a tendency for the armature current to increase as the diameter of the reel 13 becomes larger is counteracted by an increase of excitation of the winding 19a. A rectifier 28 prevents the bucking-action of the exciter 27 from exceeding the predetermined value represented by the voltage-drop across resistor 20. In order to prevent the armature voltage of the motor 19 from reaching zero value when the motor is stationary, the exciter 27 is connected to the field winding 21a of the generator 21. The motor 19 will thus exert stalled torque upon the reel and thereby maintain the desired value of tension in material 10 with the reel at rest. In place of tachometer generator 23, a compound rheostat of the type described in Specification 684,882 having its adjusting element coupled to that of the regulator of the field winding 17a, may be used for supplying the winding 21a with an excitation voltage proportional to the speed of the motor 14, Fig. 3 (not shown). A similar compound rheostat may be connected to the armature of the exciter 27 and with the field winding 21a for supplying the latter with an excitation voltage proportional to the output of the exciter.

Title: Improvements in or relating to load control systems for electric power plant
IPC: H02J3/06
Filed: 1927-06-28
Abstract: 273,717. British Thomson-Houston Co., Ltd., (Assignees of Darling, A. G.). June 30, 1926, [Convention date]. Running generators in parallel; regulation, automatic. - A power supply system comprises sources 31 such as hydro-electric generators, in which the supply of available energy is to be conserved, boilers 5, 6 fed with waste heat such as derived from copper smelting or lumber operations, the waste heat being utilized to the maximum, and a stand-by boiler 7. The boilers 5 - - 7 supply through a steam-main 8 turbogenerators 21, 22 operating in parallel with the sources 31 to supply load circuits 33. With increase of waste heat supply, the pressure in the main 8 rises, causing a Bourdon tube 55 to move a contact 57 closer to a continuously rotating cam contact 60, thereby closing a relay 47 to energize bus-bar 44 supplying split field motors 35. These rotate so as to alter the governorsetting of the turbines 21 to cause them to take additional load and therefore utilize all the waste head. With decrease of waste head supply, a contact 58 is moved closer to contact 60, and relay 49 closes to energize bus-bar 43, whereupon motors 35 operate to cause turbines to take reduced load. If fall of pressure in main 8 is due to a large load coming on the generators 22 due to loss of power in the generators 31, then the generators tend to slow down, the corresponding decrease of frequency causes relay 72 to close and thereafter dash-pot delayed relay 73 to open. Thereupon relays 48, 50 open interrupting the circuit to the bus-bars 43, 44, whereupon the governors of the turbines 21 function in the normal way to maintain constant speed irrespective of the steam pressure being low. This action causes a big demand for steam, and the low pressure in the main 8 causes a device 19 to energize a contactor 15 to start a motor 13 driving a blower and oil feed pump of the stand-by boiler 7, so that this boiler then supplies the extra demand for steam. The contacts 57, 58, 60 cause regulation in steps so as to prevent hunting, the frequency of the steps being controlled by a resistor 64.
