Filed: 1977-09-21
Abstract: In this method, an electronic maximum demand indicator with a computer, preferably a microcomputer (MC), a non-volatile memory (SP), and a display device (A) linked to it is used. Because the number of available inputs and outputs is limited by the components, a multiplex device, which is controlled by the computer (MC), is used, in order to make multiple use of the available connections. Also, different codes are assigned to the individual parts of the circuit, to prevent commands being confused, and so that data lines can be exploited doubly. <IMAGE>

Title: Improved fountain pen
IPC: B43K5/18
Filed: 1957-12-19
Abstract: 831,629. Reservoir pens. MONTBLANCSIMPLO G.m.b.H. Dec. 19, 1957 [Dec. 22, 1956; Nov. 7, 1957], No. 39501/57. Class 146(3) A fountain pen has a feed bar comprising shaft and tongue portions 1, 3 of which the shaft portion has an air duct therein and the tongue portion comprises a resilient longitudinally extending main rib 5 which carries a plurality of transverse auxiliary ribs 6 which define ink-receiving chambers 7, and a capillary slot for the flow of ink extends from the shaft portion 1 along the main rib 5 to the end of the latter remote from the shaft portion, which end presses resiliently against the underside of the pen nib 4, the rest of the tongue portion being spaced away from the nib. In Fig. 1 the main rib 5 is divided by the capillary slot 12 which extends rearwards through an annular groove 17 in the shaft portion to a curved capillary goove 18 communicating with the bottoms of the chambers 7 and also with a trough 16 at the tip of the tongue portion 3 and adjacent to the underside of the nib. The ribs 6 are separated from the underside of the nib by a space 10 communicating with an air duct 24 which leads into the annular groove 17. An interrupted capillary groove 11 is formed in the upper ends of the ribs 6. Ink is fed to the trough 16, which supplies the nib. along the capillary groove 18 and slot 12. Air is drawn into the reservoir to replace used ink through a hole 14 in the nib, the space 10, duct 24, annular groove 17 and in the form of bubbles through the ink passing along the part 23 of the slot 12. If ink reaches the air duct 24 it will be stored in the chambers 7 with the assistance of the groove 11 until drawn out into the slot 12 during writing. The chambers 7 also accommodate any excess of ink fed along the slot 12. At its lower side the slot 12 is enlarged as at 13 so as to be of non-capillary width and to prevent the slot 12 from coming into contact with any surface or member which might supply it with unwanted ink. In Fig. 9 the groove 11 and slot 12 are united, thus bisecting the ribs 6, but the main rib 5 is not completely divided in this case. The embodiment of Fig. 10 is similar to that of Fig. 9 but the ink is fed along a groove 29 over the top part of the shaft portion 1 of the feed bar and the annular groove 17 is omitted.

Abstract: 983,793. Automatic voltage regulators. A.P.T.ELECTRONIC INDUSTRIES Ltd. Oct. 18,1963 [Oct.19, 1962], No. 39627/62. Heading G3R.  Apparatus for supplying a regulated D.C. voltage between output terminals comprises a plurality of series-connected D.C. input sources each of which is associated with an input path the resistance of which is varied periodically between upper and lower limits in dependence upon the sensed output voltage. As shown, three sources S1, S2, S3 are connected effectively in series to supply a load RL, and switches SW1,SW2,SW3 are included respectively in one output lead of the sources, diodes D1,D2,D3 being connected across the switched outputs of the sources. The output voltage at terminals T is applied to an amplifier A for comparison with a reference voltage,and the differential output from the amplifier controls the operation of a modulator M associated with an oscillator 0 and connected to the switch SW1. The output from the modulator switches SW1 on and off periodically, the duration of on and off periods being automatically controlled in dependence upon the output voltage which thus tends to remain constant. Switches SW2 and SW3 are connected so that they operate in unison with the switch SW1. When the switches are in the off condition the stored energy in an inductor L, which acts in association with the diodes D1,D2 and D3,is utilised to maintain the flow of current through the load RL. The switches SW1, SW2, SW3 may comprise transistors.

Abstract: 1,040,299. Pneumatic hoists; load balancing. GLOBE PNEUMATIC ENGINEERING CO. Ltd. Oct. 22, 1963 [Oct. 23, 1962], No. 39993/62, Headings B8B and B8H. A pneumatic hoist is so arranged that when a load is held suspended it may be easily and repeatedly adjusted vertically within the lifting range of the hoist by upward or downward manual force exerted directly on the load by an operator. As shown the hoist comprises a piston 1, with a piston rod 2, slidable in a cylinder D. A further piston 4 slides in a cylinder 3 and has a spring 5 so rated that the piston 4 will not rise to its upper limit unless the hoist is loaded beyond its lifting capacity. To lift a load it is attached to a hook 2a and a control handle 47a pulled to depress a spool valve R in a device B to connect pressure air from a duct 20 via a restrictor 48, spool valve R, duet 51, spool valve L and duct 52 to below the piston 1 in the cylinder D. At the same time a chamber 24 in a device C is connected to the atmosphere via port 28, port 50, spool valve R, duct 53 and restrictor 54. A clamp 23 on the piston 4 is thus released, assumes a position determined by the load and the spring 5, and in so doing adjusts the position of a valve 9 in a pressure regulating device A via a lever 8a, a plunger 8, a spring 10 and a diaphragm 14. A pressure P2 is thus transmitted to both sides of a diaphragm 32 in the device B. On release of handle 47a spool valve R1 rises and the load ceases to rise, being held stationary by the pressure P2 transmitted from port 12 of device A. Mains pressure is again transmitted to part 28 to force clamping block 23 against the piston 4. This balanced state is shown in Fig. 3. From this condition if an operator applies a manual downward force on the load the resulting increase in pressure below the piston 1 is transmitted via port 52, spool valve L, duct 51, spool valve R, port 39 and duct 40 to a chamber 33 forcing the diaphragm 32 off a port 31 allowing some air to escape past a ball-valve 25 through an exhaust port 30 to the atmosphere. Releasing the manual pressure allows the condition of balance to be resumed at the new position. If, however, an upward manual pressure is applied to the load the pressure below the piston 1 falls, a ball valve 37 opens allowing extra pressure air into the system so that on release of the manual pressure the condition of balance is resumed.
