Patent GB-102575-A (GB)
Title: Improvements in Electric Devices for Automatically Turning Lights On and Off.
Inventor: STEIGER EUGEN
IPC: F16D3/78
Filed: 1916-05-22
Abstract: 102,575. Steiger, E. May 22, 1916. Electro-magnetic switches.-In switching-devices for lamps, comprising a selenium cell s, the varying resistance of which, owing to light effect, is used to turn the lights on or off, a resistance W is automatically cut into the cell circuit during the day, when its resistance is low and cut cut at night so that more sensitive switching is obtained. The cell is in a circuit including windings 6 on the poles of a permanent magnet 5. A plate 8 forming a vibrating armature bears against an arm 10 on a spring-retracted contact lever c, d. During the day-time, the armature is deflected sufficiently to maintain the lever in the position shown, the lighting-switch L is open, and the resistance W is in series with the cell. As darkness approaches, the weaker vibrations of the plate 8 allow the spring 11 to close the contacts d, f and complete a circuit through the contact reinforcing magnet h and the coil i of the lamp switch. As this switch closes, the turning of the disk 22 throws over the lever 20, opens the contacts at 31, and lifts the lever 25 over the latch 26. The closing of the lamp switch short-circuits the resistance W so that the plate 8 may again vibrate strongly; but owing to the break in the circuits no effect results from the closing of the contacts c, e. When it is still darker, the spring 11 once more closes the contacts d, f, which close a circuit through the magnet 28 to release the latch and allow the contact at 31 to be completed ready for the switching-off when daylight returns. In a modification, the double contact lever 25 and its latch and actuating-lever 20 may be dispensed with. A dashpot may be connected to the contact lever c, d.
Patent GB-707337-A (GB)
Title: Manufacture of 1.4-dihydrazinophthalazines
IPC: C07D237/34
Filed: 1952-03-21
Abstract: The invention comprises a process for the manufacture of 1 : 4-dihydrazino-phthalazines by treating 1 mol. of phthalic dinitrile or a nuclear substitution product thereof with at least 3 mols. of hydrazine.  The reaction may be carried out with the addition of weak acids and at temperatures not exceeding 100 DEG  C. In an example phthalic dinitrile is reacted with slightly more than 3 mols. of hydrazine hydrate in dioxane with the addition of acetic acid.  The 1 : 4-dihydrazinophthalazine is converted into the following derivatives: di- and tri-acetyl derivatives (by reaction with acetic anhydride at 90 DEG  and 130 DEG  C.); phthalazine-1 : 4-diphenylhydrazone (by reaction with benzaldehyde); the dipyrazolone (by reaction with aceto-acetic ester; the dihydrazone (by-reaction with acetophenone); and the di-(o-nitrophenylhydrazone (by reaction with o-nitro benzaldehyde).

Title: Apparatus for counting and indicating the points scored by players in the game of billiards and the like
IPC: A63D15/20
Filed: 1919-03-25
Abstract: 137,190. Ravald, L. P. March 25, 1919. Scoring and marking apparatus.-An apparatus for scoring billiards &c. comprises, in duplicate, a fixed front dial A provided with an aperture for displaying the numerals on two disks B, C which are rotated by means of an outer ring of knobs F. The front disk A has attached thereto the ends d3, e<3> of two flat springs d, e which carry at their inner ends two catches d<1>, e<1> engaging teeth c<1> on the tens dial C. The units dial B is rotated by means of revoluble knobs F, and the transfer from the units to the tens dial is effected by means of half-ball projections B<3>, B<4> on the dial B. The half-ball projections push back the catches d<1>, e<1> clear of the teeth c<1>, and the tens dial C is carried forward one step by frictional contact with the units dial B, after which the catches d', e<1> again become operative. The operation is reversible to allow a score to be deducted by rotating the units disk backwards. The fixed front disk A is numbered, so that by grasping the uppermost knob F, the units dial may readily be rotated through the desired number of units. The number of dials may be increased. The knobs F may be replaced by finger-holes.

Abstract: 416,322. Navigational &c. plotting- instruments. HORNE, A. N. C., Grosvenor House, Park Lane, London. March 11, 1933, No. 7461. [Class 97 (iii).] An instrument for plotting bearings on a chart comprises an apertured base board, on which the cardinal points of the compass are indicated, and a member adapted to rotate within the aperture and carrying an apertured arm. In the form shown a square base member 1 is marked with the four cardinal points of the compass and subsidiary graduations 2 and has a central circular aperture in which a freely rotable disc 3 is held by an integral diametral arm 4 having ends passing under a concentric lip 6 on the member 1. The instrument is particularly intended to facilitate the preparation of meteorological charts. Windows 7, 8 on the arm 4 enable the graduations and code number of the wind to be seen whilst a window 9 enables symbols representing the direction and strength of the wind or ocean swell to be drawn or impressed by using the appropriate one of a series of stamps. The slot 9 may be recessed or tapered so that the stamps can only be inserted in the correct direction.

Abstract: 589,530. Kettles; teapots. RUSSELL, R. March 26, 1945, No. 7570 [Class 66] [Also in Group XXIX] A kettle &c. 1 has a handle formed of two and an opening 4 at the top normally sealed by a plate 7 which fits against the underpart of a seating 5 and is secured to the inside of the kettle by a spring member 8, downward movement of the plate being limited by a bracket 6. A teapot placed on the upper part of the seating 5 depresses the plate 7 and allows steam to circulate around the base of the pot, this being facilitated by perforations or castellations in the base ring of the pot and the projections 9 on the plate. The handle 10 is pivotally mounted on the kettle to enable the pot to be placed in position. The bracket 6 may be replaced by a second spring member attached to the plate and kettle diametrically opposite to the spring 8. In a further modification, the plate may be loaded with a spiral spring retained in a tubular member secured to the base of the kettle, in which case the top of the tube is flared to act as a stop.

Abstract: 124,948. Heap, A. C. May 14, 1918. Relay devices ; sounds, controlling and actuating apparatus by.-Apparatus by means of which a cumulative effect is obtained from subaqueous sound signals comprises a valve member 1 bearing against a seating 3 and having the hydrostatic pressure on its sides balanced. A rubber disk 6 is inflated by air towards the inside of the valve, and a passage leads from the valve to the tube 10 through the channel 8, in which the air-inflated rubber ring 9 rests. When sound waves strike the valve 1, it is slightly opened at each pulse to admit water, and the cumulative effect of a series of waves is to raise the float 11 and close a contact or the like. A slow leak is provided from the tube 10 to prevent the actuation by slower pressure changes, or by series of sound waves not of the desired duration. When the apparatus is used to explode a mine, it may be included in a subdivision of the mine casing, the enclosure being partly filled with fluid. The apparatus may be used to operate signals on buoys.

Title: Improvements in or relating to automatic feeding mechanism for gins for cotton or other fibrous materials
IPC: D01B1/04
Filed: 1925-03-26
Abstract: 254,013. Schofield, C., and Rushton. J. L. March 26, 1925. Gins.-In a feeding arrangement for a gin, in which the amount fed is automatically controlled, the cotton is fed from the chute 11 by a roller 12 and stripper 14 onto a weighing platform 26 furnished with an adjustable balance weight 28. The cotton passes on from the hopper through an aperture, which can be adjusted by a plate 18, and over a fixed guide plate 30 onto the platform 26, which is mounted on a fixed pivot 27, and is provided with a stop 41 to limit its motion. From the platform 26 the cotton passes to the usual reciprocating pusher bar 20. A curved guide 29 is provided opposite the end of the platform 26, but is so placed that the platform cannot entirely close the opening between them. The roller 12 carries a ratchet wheel 32 operated by a pivoted pawl 34 carried by an arm 35 oscillated from the crank 38 on the driving-shaft 17. When the platform 26 is depressed by an excessive feed of cotton the tail piece 39 carried by the platform rises into engagement with a pin 40 on the pawl 34 and disengages it to stop rotation of the roller 12. A detent 33 prevents any backward rotation of the roller 12. The link 37 can be adjusted to vary the rate of the feed.
