Title: Improved method of and means for producing a combustible mixture of oil and air
IPC: C10J1/12
Filed: 1955-01-24
Abstract: 783,196. Oil gas generation. HAMMACHER, J. Jan. 24, 1955, No. 1998/55. Class 55 (2). An oil gas generator plant comprises a generator 1, a vapour and air mixer 2 and an exhauster 3, the orifice 10 of the air inlet pipe 11 leading to the mixer being disposed close to cooling ribs 9 on the mouth of the generator which lies in the path of the flame from a burner 6. The combustion products are drawn into the generator, the vaporized oil being drawn into the mixer through a pipe 8. Interconnected valves 14 in pipes 8, 11 are controlled by means of a regulator 16 having a diaphragm the opposite sides of which are exposed to the atmosphere and to the oil gas offtake. Unvaporizable residues accumulating in the oil are periodically removed into a vessel 25 by means of a device 23 responsive to the rising temperature of the oil to operate a slide valve 30 so as to establish a passage between vessel 25 and the suction side of the exhauster, thereby causing the residues to flow into vessel 25 through a non-return valve 27, fresh oil entering the generator to the level permitted by a float valve 18. The residues are discharged through a pipe 33. The burner 6 is supplied with the product oil gas through a pipe 19, but the plant is started by a separate burner 26 supplied by a pipe 21 with town gas or other fuel. The air component of the oil-gas may be heated in a recuperator heated by the flue gas of the main combustion apparatus. The product gas may be compressed for delivery to the main combustion apparatus.

Patent GB-174922-A (GB)
Title: Improvements in controlling devices for the motors of electrically driven vehicles
IPC: B60L15/20
Filed: 1922-01-24
Abstract: 174,922. Krupp Akt.-Ges., F. Feb. 4, 1921, [Convention date]. Controllers with auxiliary switches.-Motor controllers are provided with an electromagnetic cut out, the releasing coil of which is energized by the closure of auxiliary switches actuated by movements of the controller drum. The object is to remove sparking from the controller fingers. In the construction shown in the drawings, a brush a<53>, Fig. 2 is attached to the actuating- spindle a<56> of a resistance and series-parallel drum controller A which has auxiliary segmental contacts a<47>, a<48>, a<49>. The brush and segmental contacts form a two-way switch in series with the releasing coil G<2> of the electromagnetic cutout. By means of a lost-motion connection between the spindle a<56> and the drum, the twoway switch changes over when the direction of movement of the controller actuating spindle is reversed, the effect being to connect the releasing coil in a low resistance path across the mains. Appropriate connections for preparing the releasing circuit are formed by a two-way switch M adapted to be changed over by cam action when the controller is passing through its neutral position. The cut-out after it has been opened by the releasing coil is maintained open by a reduced current flowing through a resistance in series with the motor armatures. In order to reclose the cut-out the controller is brought back to the neutral position, in which the switch M is changed over so as to break the existing circuit of the releasing coil and simultaneously prepare for subsequent completion as described above. Series-parallel systems.-Provision is also made for temporarily opening the cut-out during the transition from series to parallel running. Controllers, actuating and interlocking.-The controller drum A is geared by a Geneva stop mechanism, Figs. 3 and 4, to a reversing and braking drum B. Both drums are actuated by a remote hand wheel N, Fig. 5, through pulley and wire-cable transmissions Q, R. S. T. Rotary movements of the hand wheel act only upon a pulley Q connected to the drum A. Longitudinal movements of the hand wheel axle, which are permitted when the controller drum is in the neutral position, act only upon a pulley R connected to the drum B and effect the reversal of the motor connections. A bevel gear drive between the drum B and its actuating spindle b<42>, Fig. 3, allows the reversal to be effected withoute interfering with the Geneva stop drive from the controller drum A.

Title: Improvements in or relating to fountain pens
IPC: B43K5/00
Filed: 1947-01-24
Abstract: 635,358. Reservoir pens. DEHN, S. G., (Parker Pen Co.). Jan. 24, 1947, No. 2327. [Class 146 (iii)] A reservoir fountain pen comprises an overflow ink collector which prevents excess ink from reaching the nib through which ink is drawn into the reservoir and means operative in response to replacement of a cap for the tilling mechanism on the fountain pen for actuating the filling mechanism to draw ink from the collector into the reservoir after the pen has been withdrawn from the source of ink supply. A fountain pen comprises a cellular overflow collector 13 connected to a reservoir 12 by a breather tube 18, the reservoir being filled by reciprocation of a plunger 20 carrying a flexible diaphragm 21 clamped to the barrel by a sleeve 22 secured by a nut 24. The plunger 20 is urged rearwardly by a spring 36 interposed between the head 37 of a latch 38 having a blade member 42 and a key 39 working in slots 40 in the plunger and fixed to the sleeve 22. During depression of the plunger a stop 43 slides inwardly ; the stop engages the key 39 on the return stroke thus limiting its outward travel, Fig. 3. The key 39 is released when the pen has been removed from the supply of ink by replacement of a cap 28 which carries a release member 44 which presses the latch 38 outwardly. The plunger then completes its return stroke to drain the overflow 13. In a modification, the limiting means for the return stroke of the plunger is dependent on the rotation of the plunger during the inward stroke which is released by screwing on the end cap. Further modifications describe the application to a collapsable sac pen in which a presser bar co-operates with a cam surface so that the sac is slightly compressed when a plunger actuating the presser bar is fully extended but the sac is fully expanded by moving the plunger inwardly by screwing on a cap covering the plunger.

Title: Improvements in apparatus for reproducing recorded sound
IPC: G11B3/00
Filed: 1928-01-26
Abstract: 284,290. K³chenmeister, H. J. Jan. 27, 1927, [Convention date]. Optical apparatus; optical records. - Light is transmitted from a single source simultaneously through two or more points which lie on two or more separately-recorded but similar photographic records and are displaced in phase relatively to each other, the light passing to photo-electric cells whereby sound-reproduction is effected with the well known improvement in quality due to such phase displacement. Fig. 1 shows an apparatus in which a film record i passes over a curved guide a, at the centre of curvature of which a lamp b is placed. Light from the lamp passes to selenium cells g, h through two optical systems c, d, and through two apertures e, f and is thus transmitted through two separated points on two records of the same piece of music which have been simultaneously recorded on the film. The lamp may have two independent filaments, one of which serves as a reserve source if the other burns out. Instead of using a curved guide for the film, a straight guide may be provided, in which case mirrors are employed for reflecting light from the optical systems through the apertures. Fig. 3 shows a further arrangement, embodying a reflecting prism 7n in conjunction with a single source k, an optical system l, and mirrors o. to illuminate separate phase-displaced points on separate records on the film i. Records may be used in which the sound is recorded on a band of polished metal, in which case reproduction is effected by means of reflected light. The Specification as open to inspection under Sect. 91 (3) (a) states also that a single source of light may be used for transmitting light through two or more points of a single record, or may be used for reproducing orchestral music &c. from separate records of the sound from different instruments &c., which records have been made simultaneously. It refers, further, to means for automatically switching on a spare or reserve source of light if the one previously in use should fail, and also describes the use of a double-filament lamp having a hand-operated switch by means of which a change over from one filament to the other may be made. This subject-matter does not appear in the Speciflcation as accepted.
