Filed: 1925-06-24
Abstract: 244,701. Hauton, P. S. Dec. 18, 1924, [Convention date]. Pencil holders; erasers.-In a screw-propelling pencil holder, the screw-threaded feed tube is extended beyond the lower end of the outer casing and is arranged to act as a clutch for the lead. The lead-holding tube projects beyond the upper end of the casing and is rotated by an eraser ferrule, the lead-holding tube passing through and being crimped over a restricted portion of the ferrule. The screw-threaded tube may also project beyond the upper end ef the casing and serve as a guide for the ferrule. As shown in Fig. 1, the feed tube B is secured by friction or adhesive in a casing A preferably formed as described in Specification 242,709, and its projecting lower end is tapered to form a guide tip B" for the lead. The lead-holding tube C is of slightly larger diameter than the lead, and is split at the front end and formed with an internal projection C" serving as a further support for the lead, the segments of the split end being arranged to bite into the lead to prevent rotation. The follower J is preferably formed from a piece of wire having a flattened sinuous portion forming extensions which pass through a longitudinal slot in the tube C into engagement with the screw.-threads on the tube B. The rear end of the tube C is secured to a cup-shaped member D' locked to an eraser ferrule E so that the rotation of the ferrule results in the propulsion or retraction of the follower J. At its rear end the tube B is formed, at a short distance from its end, with a number of longitudinal slits Q, and with an internal rib R acting as a clutch for the lead. A swollen portion S' in the tip serves as a bearing for the tube C. In a modification of the mounting of the eraser ferrule, the feed tube B terminates with the. casing, and the restricted portion of the ferrule is engaged by the crimpedover end of the tube G is lengthened to aid in maintaining the parts in alignment.

Title: Improvements in tone-control circuits for low-frequency amplifiers
IPC: H03G9/08
Filed: 1949-06-22
Abstract: 681,359. Thermionic valve amplifiers. PHILIPS ELECTRICAL, Ltd. June 22, 1949 [June 25, 1948], No. 16596/49. Addition to 640,184. Class 40 (vi). In a modification of the circuit arrangement of the parent Specification, which comprises a valve amplifier with a frequency dependent negative feedback taken from a potentiometer and varied in frequency relation according to the position of the sliding contact of the potentiometer, wherein two fixed contacts of the potentiometer are supplied with a voltage proportional to the output of the amplifier through a filter passing intermediate tone frequencies and a filter passing low tone frequencies respectively, and a third fixed contact and/or the sliding contact is connected to the grid of the valve and/or to the source of the voltage proportional to the output through an impedance of low value to the high tone frequencies so that if the slider is near the third fixed contact a heavy negative feedback of the high tones is provided, the intermediate tone frequencies are relatively attenuated in the preceding channel and the intermediate tone band-pass filter connected between one fixed contact of the potentiometer and the feedback source is replaced by a filter passing the intermediate and high tones connected between the fixed contact and a point of constant potential. The grid circuit of the amplifier 3 includes a physiological gain control according to Specification 644,174, comprising a potentiometer 24 connected between the audio-frequency input and a source B of negative feedback on the secondary 30 of the output transformer. Intermediate tone frequencies are fed back from B to a third fixed contact on the potentiometer through condenser 35 and resistor 36. Positive feedback from D is applied to the top of the gain control potentiometer through resistors 34, 40 so that substantially no negative feedback is effective at that point. The effect of intermediate tone pass filters 33, 34 and 35-36 ensures that, as the gain is reduced, the intermediate tones are attenuated relatively to the high and low tones. The tone control potentiometer 5 is connected at one end a through a low tone pass filter 6, 7 to a source A of heavy negative feedback, and at the other end c to the sliding contact of the gain control and the grid of the valve 3. The sliding contact of the tone control is connected to A or another tapping on the output secondary 30 through a condenser 14, passing only high tone frequencies. An intermediate fixed contact b on potentiometer 5 is earthed by condenser 20 passing high and intermediate tone frequencies. Since the gain control circuit provides a heavy feedback of the intermediate tone frequencies, when the sliding contact of the tone control 5 is near fixed contact a, low and intermediate tone frequencies are fed back, while with the slider at c, the high and intermediate tone frequencies are fed back. If the slider is near fixed contact b only the intermediate tone frequencies are fed back.

Title: Improvements in or relating to steam power plants
IPC: F01K3/02
Filed: 1930-05-29
Abstract: 346,216. Steam power plant. RUTHSACCUMULATOR AKTIEBOLAG, 1A, Eriksbergsgatan, Stockholm. May 29, 1930, No. 16664. Convention date, June 5, 1929. [Class 110 (iii).] In a steam power plant in which a turbine or other power unit 1 is supplied with live steam from a pipe 2 and low-pressure steam from an accumulator or boiler 5, the pressure in the pipe 2 is maintained approximately constant by means of a pressure-controlled valve 7 which controls the amount of steam supplied to the turbine from the accumulator 5. Speed-controlled valves 4, 9 are supplied in the two steam lines 3, 6. An increase in pressure in pipe 2 causes a closing movement of the valve 7, the turbine receives less steam from the accumulator and slows down and the valve 4 opens to admit more live steam until conditions are normal. On increase of load on the turbine the speed regulator 4 increases the supply of live steam and the consequent lowering of pressure in pipe 2 causes valve 7 to open wider. In case of a considerable lowering of turbine load when the pressure in pipe 2 is also below normal the speed regulator 9 functions to prevent the flow of too much accumulator steam to the turbine. A speed regulator 11 is provided in a byepass line around the valve 7. The regulator 11 is closed normally but opens when the turbine speed is very low and the pressure in pipe 2 is above normal. The control devices 7, 9, 11 may be combined into one unit. Accumulator steam may be led to a single stage of the turbine or to several stages which are controlled by the pressure existing in pipe 2.
