Title: Improvements in atomizers for liquids, more particularly for use with oil fuel fired furnaces
IPC: F23D11/24
Filed: 1938-05-05
Abstract: 513,712. Spray-producers; liquid-fuel burners. HUSTER, A. May 5, 1938, No. 13466. [Class 69 (iii)] [Also in Group XI] A liquid such as fuel oil is atomized by passage through ducts formed between a tapering screw thread or threads 9 in an axial bore 8 in a nozzle head 7 and a cylindrical member 11 having a semi-ellipsoidal tip 12 projecting into a spraying orifice 18 in a nozzle plate 14 which is secured by a nut 13 to the head 7 so as to have a liquid-tight joint with the top face of a boss 15. The oil is supplied through a conduit 1 having a restricted orifice 2 to a housing 3 and tube 4 carrying the head 7. The member 11 is guided by a perforated partition 20 forming with the head 7 a chamber 10 and is connected at its rear end to the housing 3 by a diaphragm 24. A rearward extension 25 of the member 11 is formed with collars 29, 31 which may be engaged by a diaphragm 27 and an adjustable cap 30 on a housing 26 adjustably threaded to the housing 3. By means of the diaphragm 27 stress can be applied to the diaphragm 24 to cause a conical surface 11<1> on the member 11 to engage the conical surface on the orifice 18 but the axial movement of the member 11 may be limited by a collar 23 on its surface engaging the partition 20. The pressure of the oil against the stressed diaphragm 24 causes a displacement of the member 11 and a proportionate regulation of the discharge from the orifice 18. The tip 12 is preferably so shaped that a movement in the direction of the oil flow causes the discharge opening from the thread groove to diminish more rapidly than the annular opening between the tip and orifice 18. A piston disc 33 on the extension 25 damps oscillation of the member 11. If the oil discharge is impeded by foreign matter the pressure in the housing 3 increases and the member 11 is operated to enlarge the discharge passages and enable the foreign matter to be ejected. The member 11 may be adjusted irrespectively of the fuel pressure by the cap 30 and may be locked in position by a nut 32. Instead of the restriction 2 an oil filter may be fitted in the conduit 1 and the diaphragm 27 may be replaced by a spring or weight. The sides of the groove 9 preferably are inclined at an angle of 90 degrees.

Title: Combined motor and relay electric timing device
IPC: G04F3/06
Filed: 1963-04-04
Abstract: 1,016,355. Switches, partly electromagnetic. GENERAL TIME CORPORATION. April 4, 1963 [Aug. 24, 1962], No. 13508/63. Heading H2B. A device for connecting a supply to a load after a predetermined time interval from closure of an initiating switch comprises a relay 11, Figs. 1 and 2 (not shown), having contacts 26, 27 in the load circuit and holding contacts 22, 23 in the circuit of its winding 16, combined with a synchronous motor 12 arranged to drive a cam 30 until it closes the relay holding contacts 22, 23 by direct mechanical engagement with follower 35 mounted on contact spring 21 as shown. Contact 23 is connected to main supply by closure of an external initiating switch (Fig. 4, not shown), and motor 12 is energized over contact 21, causing its armature to move axially and thereby engaging gearing (Fig. 3, not shown) to drive cam 30 clockwise against the tension of a spiral spring 52. When cam 30 engages follower 35 contacts 22, 23 are closed and winding 16 is energized to attract armature 17, thereby maintaining contacts 22, 23 closed and separating contacts 21, 23. This de-energizes the motor 12, its armature is spring-urged out of engagement with the gearing to cam 30 which returns under action of spring 52 to its rest position (Fig. 1, not shown) wherein a lug 50 abuts a stop 51. The relay also maintains its contacts 26, 27 in the load circuit closed until the initiating switch is opened to remove the main supply from contact 23. Cam 30 is adjustably secured to drive shaft 32 by a nut 55 to provide variation of the time delay. In an alternative embodiment, not illustrated, the restoring spring 52 and stop 50, 51 are not provided and the cam is arranged to pass beyond the follower 35 due to momentum of the motor after switch-off, it then being in readiness for a subsequent cycle. In this case the motor speed and gear ratio is chosen such that the desired time delay corresponds to one full revolution of the cam.

Title: Improvements in or relating to the manufacture of cigarettes
IPC: A24C5/52
Filed: 1933-09-21
Abstract: A mouthpiece cigarette is made by first aligning a cigarette and a mouthpiece or stub, moving them axially, and then while they are so moving, securing wrapping material, e.g. a cork tip, around the adjacent ends of the cigarette and stub to unite them. Alternatively, two cigarettes with a double-length stub between them are united by wrapping material, the composite cigarette being then cut through the stub to form two cigarettes. Preferably, however, double-length cigarettes and stubs are employed alternately in a continuous stream in the machine described in Specification 430,742, the composite rod so formed being cut through the stubs and also between the ends of each cigarette.  In a modification a continuous length of wrapping material instead of short lengths of tip material is applied to the cigarettes and stubs so that a continuous rod is formed which is thereafter cut to the desired lengths.  A stub is defined as a mouth-piece in the form of a paper tube which may be empty or filled entirely or partly with filtering or flavouring material or tobacco, a composite mouthpiece constituted in part by a length of wrapped tobacco rod and in part by a length of filtering or flavouring material wrapped in a tubular wrapper or by a tubular piece which is either hollow or entirely or partly filled with filtering or flavouring material, or a mouthpiece comprising a length of tobacco filler in a wrapper which tobacco is of a different kind from that in the cigarette.  Specifications 425,480 and 430,817 also are referred to.

Title: Improvements in apparatus for generating ultrasonic waves
IPC: B06B1/02
Filed: 1953-05-18
Abstract: 724,484. Ultrasonic inspection devices. SPERRY PRODUCTS, Inc. May 18, 1953 [June 12, 1952], No. 13866/53. Class 118 (2) [Also in Group XL (c)] To produce an ultrasonic wave train of a predetermined number of cycles only, a crystal transducer is associated with two electrically independent wave train generators. Means are provided to energize these and the output of the first is applied to the transducer to initiate the wave train while a delayed and shaped output is obtained from the second commencing at a time corresponding to the end of the desired wave train and is used to cause mechanical vibrations at the face of the transducer equal and opposite to those existing, due to the first generator. The arrangement is of particular use in flaw detectors where echo signals due to flaws close to the surface may require detection and would otherwise be lost in the decaying transmitted pulse. In the preferred embodiment, a multivibrator 20 generates a waveform which is applied to the grids of normally conductive valves 21 and 21<SP>1</SP>. The outputs of these valves are differentiated at 22 and 22<SP>1</SP> respectively and the positive peaks only are passed by cathode followers 25, 25' and serve to trigger thyratron valves T and T'. When the valve T fires, condenser 30 is discharged and the resulting wave train of a form determined by circuit 31 is applied through isolating stage 32 to crystal transducer 10. Due to the variable delay introduced by circuit elements 26 and 27, the thyratron T' may be made to fire at any desired time after thyratron T and the discharge of condenser 30' initiates a second wave train which is shaped by elements 35, 36 and 37 to cancel out the remainder of the first wave train when applied through isolating stage 32' to the transducer. Instead of using isolating stages 32', the electrical wave trains may be applied to separate energizing electrodes on a single crystal transducer,
