Title: Method of and apparatus for making gas of the nature of producer gas from liquid fuel
IPC: C10G9/38
Filed: 1928-08-10
Abstract: 322,733. Triggs, W., W., (Williams Oil- O-Matic Heating Corporation). Aug. 10, 1928. Oil gas.-A gas of the nature of producer gas is obtained from liquid fuel by delivering a mixture of oil and water with air under pressure to a mass of refractory material, the air supply being reduced when the material is heated to a state of incandescence. A motor 1, in connection with a thermostat 2, drives an atomizing pump supplied with oil from a pipe 3, water being fed through a pipe 4 to mix with the oil, and the mixture of oil and water is passed by a pipe 10 to a gas producing chamber 5 containing refractory material 6. An intake 9 leads to the atmosphere and an independent gas supply 12 and sparking plug 11 are provided for starting purposes. For gas making, the motor is started, oil and water sprayed through the pipe 10, and air drawn through the conduit 9, the material 6 being rendered incandescent and the fired gases escaping through an outlet 13 to a burner 14 in a furnace 15, which may form part of a domestic heating system controlled by the thermostat. When the material is incandescent a bi-metal strip 19 causes a rod 17 to fall, which tends to close a valve 16 in the air inlet pipe, and a mercury switch 21 breaks the circuit which energizes the spark coil 22 and a solenoid 23 which closes' a valve in the gas supply pipe 12. A rich oil mixture is thereby obtained and the resultant gas is of the nature of producer gas. In a modification, Fig. 5, the motor is mounted on the air conduit 8 and drives a fan 27 and conical sleeve 28, pipes 3 and 4 delivering the oil and water respectively, which are thrown against the side walls of the chamber 5 in an atomized condition, the gas produced passing through the material 6 to a discharge pipe 30. The fan has an intake on the upper side through which air is drawn in and discharged through a pipe 29. In other modifications the fan is in a separate external casing and is driven by a motor separate from that which drives the centrifugal oil distributor or the latter may be driven by a turbine rotated by the air current from the fan. Specification 20980/89 is referred to.

Title: Improvements in or relating to projectiles for use in catching whales and other mammals
IPC: F42B30/14
Filed: 1921-08-31
Abstract: 189,247. Henkes, A. Aug. 31, 1921. Addition to 165,478. Projectilles.-An inflating whaling projectile of the kind described in the parent Specification has a member, axially alined with the inflating gas container, and capable of axial displacement to effect release of the non-explosive inflating gas or to initiate a chemical action evolving such gas. Explosion of a charge in the nose 3, Fig. 1, forces the piston 16 rearwardly so that the pin 15 pierces the cap 17, thus allowing the inflating gas to escape from the container 1 through the passages 5, and so that the disc 14 forces outwards the barbs 6, 7. If no explosion takes place, barbed levers 6, 7 are opened out by pulling on a line attached to the projectile so as to actuate the pin 15, through a disc 14 slidably mounted thereon, to pierce the cap 17. Resilient washers 22, normally held in grooves 20 in the casing 2 by spring-pressed rings 23, are released on impact and spring into the dotted position shown and serve to plug the hole made in the body of the target; the washers 22 are of increasing thickness and of decreasing diameter from front to rear or may all be of equal size. In a modification, the pin 15 forces rearwardly a sleeve sliding on a forward tubular extension of the gas container 2, so that holes in the sleeve coincide with slots in the extension to allow the gas to escape. In the modification shown in Fig. 3, a heavy collar 40, surrounding the tubular extension 37 of the container, slides forwardly against a spring 41 on impact, to allow the gas to escape through slots 42, 32. In Fig. 5, a sleeve 51 surrounding the rear portion of the projectile has resilient projecting parts 52 by means of which the sleeve is stripped off when the projectile enters the target, projections 58 thereon passing slots 59 in abutments 21 and contacting with pivoted arms 57 to force forward a sleeve 55 sliding on the extension 62 of the container, so that the gas may escape through openings 61, 60, 53. The resilient washers 50 are released when the sleeve is stripped off. In a modification, the projections 58 are dispensed with, and a construction, similar to the parts 37, 40. Fig. 3, replaces the parts 55, 62; the projections 52 in this case are pivoted to the sleeve and outwardly spring-pressed.

Title: Improvements in or relating to transistor function tables
IPC: G11C8/02
Filed: 1956-07-31
Abstract: 829,954. Electric selective signalling systems. SPERRY RAND CORPORATION. July 31, 1956 [Aug. 5, 1955], No. 23650/56. Class 40 (1). A matrix-type circuit for converting a combination of markings on a number of input leads to a single marking on one of a plurality of output leads is characterized in that it uses transistors. In a first embodiment one of four output loads 18, 19, 20, 21, Fig. 1, is caused to pass a high current (relative to the current in the other loads) in dependance upon the particular combination of on states of two flip-flops 22, 23. For example, when the left-hand leads 14, 16 of the two flip-flops are both positive transistors 24, 25, 28, 29 (of the NPN type) have their bases positive with respect to their emitters and therefore present a low impedance to earth from leads 10, 11, 12. Thus current on these leads 10, 11, 12, from potential source V passes to earth via a transistor rather than via a load 18, 19, 20, whereas the current on lead 13, which is not associated with a low impedance transistor, passes via output load 21. In a second embodiment (Fig. 2, not shown), the output loads are inserted in the horizontal leads to the left of the limiting diodes and as a result a particular load is marked by passing a lower current (instead of a higher current) than the other output loads. Further pairs of complementary embodiments are described (Figs. 3, 3A and 4, 4A, not shown) which use, respectively, six and four NPN transistors. A final embodiment (Fig. 5, not shown) using six PNP transistors is also described.

Abstract: 486,377. Television ; valve amplifying circuits. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. Aug. 30, 1937, No. 23708. Convention date, Aug. 29, 1936. [Classes 40 (iii) and 40 (v)] Picture signals 46 in a transmitter are amplified to an extent which is automatically controlled in dependence on the peaks of the signals. The gain of amplifiers 16, 17 of signals from a scanner 1 is controlled by a varying bias obtained from the signals. Valves 32, 33 effect automatic control in dependence on the amplitude of the signals in the " white " direction, and the valves 49, 51, 52 in dependence on the amplitude in the " black " direction. The signals are applied to the grid 34 of the valve 33, which has a resistance 37 between the controlling grid and the cathode 36, and at least part 38 of the resistance is shunted by a condenser 39. " White " peaks in the signals cause grid current to flow and thus produce across the condenser a voltage which effects automatic control of the amplifier 16 or 17. The condenser and resistance have a time constant at least equal to the period of one scanning. Automatic control by the " black " peaks is obtained from the valve 52 in a similar way.

Title: Improvements in road traffic control systems
IPC: G08G1/082
Filed: 1939-08-17
Abstract: 534,027. Road signals for controlling traffic. SIEMENS & GENERAL ELECTRIC RAILWAY SIGNAL CO., Ltd., and DOWNES, F. A. Aug. 17, 1939, No. 23757. Drawings to Specification. [Class 118 (ii)] The progressive system described in Specifications 450,602 and 504,552, wherein at each intersection a prevent period and a privilege period are allotted to each road under the control of pulses received by the local controller from a master controller, is modified by the extension of the prevent period to cover the time of arrival of the leading vehicle of a group of traffic on the main road, as determined by the signalling plan, this period being followed by a vehicle-actuated period with no intervening privilege period. The arrangement is suitable at an intersection where the "up" and "down" groups of main road traffic arrive almost simultaneously and where the side road is not subject to progressive control. The system described is generally similar to that disclosed in Specification 504,552, with the principal difference that the local controller receives only 4 pulses per cycle to initiate and terminate the prevent periods for the main and side roads, the pulse-receiving relay (PA) controlling a pair of preference relays (PJ,PK) and a pair of vehicle-actuation relays (VA, VAA). The main road cannot lose right of way during its prevent period, which exceeds the minimum green period for the side road, but if right of way is on the side road, it can be extended against demands on the main road, thus the speed timer is operative only if the side road has right of way. During the vehicleactuated period, however, the speed timer is always operative. The maximum timer may or may not be normally connected up as desired, but in any case it is brought into operation as well as the speed timer should the pulses from the master controller cease. The Provisional Specification states that the system of Specification 450,602 may be modified to operate according to the present scheme by adjustment of the timers for the prevent and privilege periods, the latter being set at a very small value. Specification 534,026 also is referred to.
