Title: Pile driving apparatus and method
IPC: E02D7/24
Filed: 1972-06-22
Abstract: 1429312 Pile driving; earth-jetting apparatus HOLLANDSCHE BETON GROEP NV 22 June 1973 [22 June 1972] 29392/72 Headings E1F and E1H When driving a hollow pile 1 having an open toe-end, the plug 3 of soil forced up into the pile is maintained below a certain length by directing a jet or jets of water 4 generally transversely of the longitudinal axis of the pile, thus limiting the amount of friction generated by the soil plug. The water is supplied by a pipe 7 to a nozzle or a ring having inwardly and outwardly directed jets Fig. 2 (not shown). The jets may be inclined to the axis of the pile at angles less than right angles. When the pile 1 has been driven to the required depth the plug 3 may be compacted or consolidated by driving a pin 11, Fig. 4, into the plug, e.g. by hydraulic pressure acting on a piston 12 in a cylinder 10, forcing the pin to penetrate a guide disc 13. The pin 11 may be driven by a hammer, Figs. 6, 10 (not shown). The plug may also be consolidated by injecting a liquid via apertured pipes secured to the inner wall of the pile adjacent its lower end, which liquid expands on hardening or on contact with water. Examples given are grout comprising expanding cement, colloidal solutions of silicates, and solutions of phenoplastic resins.

Abstract: 657,709. Discharge lamps. BRITISH THOMSON-HOUSTON CO., Ltd. Nov. 12, 1948, No. 29453. Convention date, Nov. 13, 1947. [Class 39 (i)] In an electric discharge lamp comprising a tubular vitreous envelope formed to a substantially closed configuration with its ends disposed in closely spaced relation and having metal end caps fastened thereto, and a base for the envelope comprising a body of lightpervious material mounted on the envelope ends and closing the gap between them to thus complete the closed figure of the lamp, the end caps have a plurality of apertures therein for transmitting the light radiations from the lamp envelope to the body so as to illuminate the latter and thus complete the closed illuminated figure of the lamp. The lamp may be of the positive column fluorescent type having a filling of mercury vapour and an inert gas such as argon at a pressure of several millimetres of mercury. The base 14 is constructed of material such as a plastic or synthetic resin and comprises two parts 15 and 16 clamped by means of a screw bolt 18 around the lip portions 10 of the end caps 9. The latter are made of a metal such as a chrome-iron alloy and have a plurality of apertures 19 circularly arranged around their outer peripheral portions. In sealing the caps 9 to the ends of the glass envelope 1, the glass flows into and fills the apertures 19, thus forming in effect a series of small glass lenses 20 which serve to retract the light radiations from the lamp envelope on to the base 14.

Title: Analog to digital converter
IPC: G06F7/02
Filed: 1966-07-01
Abstract: 1,098,369. Analogue to digital converters. INTERNATIONAL BUSINESS MACHINES CORPORATION. July 1, 1966 [July 23, 1965], No. 29592/66. Heading G4H. An analogue to digital converter for converting a signal into a number of radix n comprises a plurality of stages, one for each denomination of the number, each having a register 251-254 for storing the associated digit, a converter 201 - 204 to produce an analogue signal equivalent to the stored digit and a subtracting amplifier 181-184 in which the difference between the input signal and the analogue signal from the converter is multiplied by n, the output from each subtracting amplifier being applied as input to the next stage. Switches 151-155 apply the original signal and the successive outputs from the difference multipliers in turn to a digitising circuit 300 having n levels of discrimination, the corresponding denomination digit being determined from the output. In the form described the radix is 8 and the denominational digits are represented by a combination of signals on three leads. Control signals are derived by a circuit 100. The input signal is applied at terminal 10. Switch 151 first connects the input to the digitiser 300 which has eight threshold devices. The output is converted to a signal on one of eight leads at 600 and at 700 to a binary scale digit on three leads. The first digit is stored at 251 and applied to a converter 201. The corresponding analogue signal is subtracted from the input at 181 and the difference multiplied by eight. The value is then applied via switch 152 to the digitizer 300 and the corresponding digit stored at 252 and converted to analogue at 202. The difference amplifier 182 multiplies the difference by 8 and the resulting value is applied via switch 153 to the digitizer. The process is repeated for five denominations for which the highest four corresponding digits are stored (251-254) and the last comes direct from the digital converter 700. At the end of the conversion, gates 900 are enabled to read out the five three-bit digits. The circuits are described in detail.

[Also in Groups XIII and XXXV] In a system for heating and ventilating an enclosure a heating liquid is circulated, the temperature of which is automatically controlled by a thermostat to maintain it at a value dependent on outside temperature, and air heated to a substantially constant temperature is forcibly supplied to the enclosure. Air is supplied to a compartment-type railway car through a duct 61, Fig. 3, supplied by a blower 63 with a mixture of outside air and air returned from the car. The air may be heated by a steam heater 64 or cooled by an evaporator 65, changeover being effected manually. Supply to steam heater 64 is controlled by a solenoidoperated valve 73, responsive to a thermostat 107, which opens to admit steam if the duct temperature falls below a predetermined temperature, e.g. 60 F. Thermostats 111 are provided for control when cooling is in operation. Branch ducts, e.g. 80, Fig. 7, supply the individual compartments, each duct being provided with an air spreader 154, a damper 117, and an electric heater 115, the two latter being controlled in the compartment by a knob 121. With damper 117 fully open and electric heater 115 off, position 1 of knob 121, Fig. 15, compartment temperature is a minimum. With the damper admitting only 30 per cent of the maximum volume of air and electric heater 115.fully on, position 11 of knob 121, compartment temperature is a maximum. Intermediate conditions selected by knob 121 are indicated in Fig. 15. A relief valve 81, Fig. 3, prevents undue rise of pressure in duct 61 when many dampers are partially closed. A relay (not shown) prevents energization of the electric air heaters when blower 63 is not operating. To conserve electrical energy when supply voltage is low the electric air heaters are cut out automatically by a low voltage relay (not sliown) and a thermostat 109, Fig. 3, introduced to control valve 73 and maintain a higher duct temperature, e.g. 68 F. Toilets have branch ducts 82, Fig. 3, associated with a main exhaust duct 83, Fig. 7, air in which is discharged outside by a blower 84.
