IPC: F02B25/00
Filed: 1916-11-29
Abstract: 111,520. Boye, F. L. Nov. 29, 1916. Two-stroke-cycle engines.-A long tube or chamber 4 open to the air is provided just above the exhaust outlet 2 so that, when the tube is uncovered on the descent of the piston, the burnt gases create a pressure on the tube but do not escape owing to the rapidity of the action, and when the outlet 2 is opened, the pressure in the tube effects the rinsing of the cylinder. The tube 4 may be connected by a passage 5 to an opening 7 high up in the cylinder and closed by a valve 6, so that when the valve is opened, the compression is reduced for starting, the pressure in the tube 4 being at the same time increased. More than one chamber and exhaust outlet may be provided.

Title: Improvements in or relating to transistor mixing circuit arrangements
IPC: H03C1/36
Filed: 1953-06-22
Abstract: 739,107. Modulating and frequency changing apparatus; transistor generating circuits. PHILIPS ELECTRICAL INDUSTRIES, Ltd. June 22, 1953 [June 25, 1952], No. 17222/53. Classes 40 (5) and 40 (6). A modulator or frequency-changhing circuit comprises a transistor associated with a resonant circuit so as to be self-oscillatory at a frequency fo, the input signal of frequency fi being applied between the emitter and base electrodes and output signal being developed between the collector and base electrodes, this second resonant circuit being tuned to twice the frequency of the locally generated oscillation, i.e. to 2fo, or to a frequency (2fofi) differing therefrom by the frequency of the input signal. In the arrangement shown, the circuit oscillates at the frequency fo due to the tuned circuit 2 connected in the base circuit of the transistor 1. The supply arrangements for the circuit are such that the oscillations are limited as shown in Fig. 3, curve i 1 , wherein is shown the variation of collector current with time for a zero value of input signal from the generator 3. Upon a change in the instantaneous value of the signal from the generator 3, an output such as shown by curve i 2  is obtained; it will thus be seen that the signal of frequency fi results in the production of pulses of current #i in the collector circuit at a frequency 2fo and modulated in amplitude by the signal of frequency fi. If the circuit is to be used as a frequency changer the filter 4 in the collector circuit is tuned to either frequency (2fo+fi) or frequency (2fo - fi); if it is to be used as a modulator the filter is tuned to the frequency 2fo. Since the filter 4 is tuned to a frequency considerably different from that of the oscillation generated by the circuit, regenerative effects due to the impedance of the circuit 4 at the frequency of the oscillation are avoided. In a modification the tuned circuit 2 is replaced by a resistor 8, and a series tuned circuit 7 is connected between the emitter and collector electrodes.

Title: Improvements relating to machines for baling hay, straw and like materials
IPC: A01F15/08
Filed: 1947-06-30
Abstract: 625,233. Baling-presses. TOPE, E. R. and TWOSE, Ltd., E. V. June 30, 1947, No. 17240. [Class 94(i)] A side-faced baling-press for hay, straw &c. comprises a plunger which is driven by a hydraulic ram automatically controlled by a valve operating in time with the ram. The invention is described as applied to a baling machine embodying the tying mechanism described in Specification 625,232. Hay &c. is collected from the ground by a pick-up mechanism 10 and transferred to a feed trough 9 from which it is delivered by reciprocating forks to the press chamber 1. The plunger 13 of the press chamber is actuated by a hydraulic ram 14. The liquid supply to the ram is provided by a motor-driven pump 20 which is connected in series with a tank 21 and a rotary valve 19. An operative connection (not shown) between the rotary member of the valve 19 and the plunger 13 causes the former to undergo one step of rotation for each forward or backward stroke of the plunger. The parts of the valve 19 are arranged so that for each step of its rotation, each end of the ram is alternately connected with the output side of the pump 20 and the input side of the tank 21. The degree of pressure on the bale may be varied by the adjustment of the inclination of the side walls 15, 16 of the baling chamber. According to the Provisional Specification the inclination of the top and bottom walls of the baling chamber may also be adjustable. A guard plate 25 which may be guided, and in part supported, by rollers, moves with the plunger to close the entrance to the baling chamber from the feed trough 12 on the operative stroke. A knife 24 is mounted at the mouth of the entrance in order to cut off projecting pieces of hay &c. as the bale is pressed down the baling chamber.

[Class 49.] In apparatus for cooking or cooling canned goods in which a rotating drum f having radial plates e between which the cans are placed and a fixed spiral h engaging the ends of the cans to carry the cans from end to end of the treatment chamber, a guide track for carrying the treated cans from the conveying device with rapid lateral movement to the pick-up device a, b is formed by continuing the last turn j of the spiral h at an increased angle and by continuing the previous turn by a spring steel or other flexible part k having its curvature adjustable, e.g. by screw m and lock nuts n, to deal with cans of different lengths. The pick-up device for the treated cans consists of a wheel formed by side-pieces a, b secured on a sleeve, the piece b being adjustable towards and away from piece a to take cans of different lengths. An intermediate piece d having recesses in its periphery holds the cans in spaced relationship. The wheel is rotated by the piece a gearing with the plates e on drum f. The plates e are cut away at the portion beneath the pick-up device and the corresponding parts i of the spiral webs h are deepened to ensure that small cans are not trapped by the guide track walls when being pushed under the pick-up device.

Discharging.-Apparatus for feeding fuel to furnaces, but applicable to discharging lime kilns comprises a hopper 10 delivering into a shovel box 11 at the bottom of which is an oscillating shovel 12 having driving gear adapted ' to yield to prevent breakage in the event of the shovel being obstructed. The shovel is arcuate in form and mounted on radial arms pivoted at 23. It is oscillated by a link 15 pivoted to a block 17 adapted to slide on an arm 18 pivoted at 19 and driven by a link 25 connected to a motor through reducing mechanism.

The weight is sufficiently heavy to insure the shovel operating under normal conditions but will yield upwardly in the event of an obstruction preventing movement of the shovel. To prevent gases from escaping through the shovel box, a pivoted gate 33 is provided and actuated simultaneously with the shovel from the pivoted arm 18 and connected thereto by links 37 and telescopic arms 38 adapted to yield against the action of springs thereon if the gate becomes clogged. An adjustable hinged flap 49 serves to regulate the size of the throat of the shovel box which may deliver through the shoot 54 bolted thereto or to a horizontal tubular member 65, Fig. 6. The bottom of the member 65 carries a notched reciprocating feeder 66 actuated from the arm 18. A damper-controlled aperture 73 admits air to the member 65 for cooling purposes.

The bolt B has a groove F into which the tongue T projects when the lever E is pulled to an outer position such that the end of the spring adjacent the tongue rests in the depression L. In this position the nut is locked on the bolt. When the lever is pushed in towards the nut, the end of the spring adjacent the tongue rests in the depression K and the tongue T is lifted out of the groove F thereby unlocking the nut. As shown, the sides of the groove F form an L-shape to enable the tongue when in its locking position to ratchet over the groove on tightening the nut and bolt, but the groove may be U-shaped.
