Title: Improvements in hydraulic dampers or shock absorbers
Inventor: STOCK CHARLES SAMUEL ROBERTS
IPC: F16F9/092
Filed: 1958-02-12
Abstract: 844,653. Hydraulic dampers. GIRLING Ltd. Feb. 11, 1959 [Feb. 12, 1958], No. 4546/58. Class 108(3). In a telescopic piston and cylinder type shock absorber having a concentric reservoir and a valve 18 between the working cylinder and reservoir disposed in the base of the working cylinder, a sleeve 19 of rubber encloses a chamber 21 which is filled with air or gas. Thus, no air or gas is in contact with the hydraulic liquid in the reservoir between the working cylinder 10 and an outer cylinder 11. As liquid flows from the working cylinder into the reservoir the gas within the chamber 21 is compressed. The sleeve J may be held against the cylinder 10 by wire rings 22. The sleeve 19 has longitudinal ribs having between them channels which provide passageways for oil to flow down to the bottom of the reservoir from ducts 24 leading from the top of the working cylinder 10 adjacent the piston rod 13. If an inert gas is used in the chamber 21 it is preferably introduced in a solid form during assembly of the shock absorber.

Title: Electronic temperature regulation for vulcanizing tires
IPC: B29D30/06
Filed: 1958-02-12
Abstract: 886,529. Automatic temperature control systems. GOODYEAR TIRE & RUBBER CO. Feb. 12, 1958 [June 20, 1957], No. 4572/58. Class 38 (4). The supply of current via contacts 36 to an electric heating resistance 12 with a positive temperature coefficient disposed inside a motor tyre during the vulcanizing of a re-tread is controlled by a relay 18 in a grid-controlled rectifier circuit, the firing of the rectifier depending on the current through resistance 12 and on that through a temperature-sensitive resistance 11 in a steam-jacket outside the tread-forming matrix for the tyre. In this way the temperature of the steam jacket and electric heater are kept in a fixed relationship which may or may not be equality depending on the setting of potentiometer 43, which selects a voltage dependent on the steam jacket temperature to balance against that across resistance 44 which is dependent on the electric heater temperature, the algebraic sum acting through transformer 28 to control gridcontrolled rectifier 16. A triode 15 the anode of which is supplied with A.C. periodically charges condenser 20 to produce firing pulses for the grid of thyratron 16; a potentiometer 23 enables adjustment of the firing point. Fig. 2 shows a modification in which the varying current through heater 12 and primary winding 80 of transformer 73 is balanced against a preset current through primary winding 93, the windings acting in opposition to produce a signal voltage in the secondary to control thyratron 16 and hence relay 18 with its contacts 77, 78 in the heater circuit. In this case the firing pulses are derived from a motordriven cycler 63, and a motor-driven timer with contacts 55 exercises an over-riding control and has an indicator lamp 57; such a timer may also be employed in the Fig. 1 embodiment. Specification 886,528 relating to a different temperature control system for a similar retread process is referred to.

IPC: F23D11/00
Filed: 1924-02-27
Abstract: 237,315. White, A. E., (Socony Burner Corporation). Feb. 27, 1924. Spray burners.-The nozzle 6 of an atomizer 4 projects an over-rich mixture of fuel and air into a cone 3 in which it is ignited by means of a sparking plug 9. Air for combustion is delivered by a fan 22 past a spider 11 supporting the cone 3 to an opening 12 between the walls of a burner chamber 1 and the cone 3. The air envelops and advances with the burning over-rich mixture while the unconsumed fuel is gasefied. On reaching the restricted outlet 2 of the burner chamber 1 the air is forced to commingle with the mixture and complete combustion ensues. Ignition at the plug 9 is facilitated by the entry of a slight quantity of additional air through an opening 13 in the cone 3. An air chamber 17 surrounds and insulates the burner chamber 1. A cup 42 is provided below the outlet 2 for collecting fuel drippings. The fan 22 is fixed to a shaft 24 which is driven through a clutch 25 by the shaft of a motor 27. The shaft 24 also operates through worm gearing 30, 31 and an eccentric 33 a pump 37 supplying air through a pipe 7<a> to the atomizer 4. The burner and fan framing are supported by posts 16<a>, 21.

Title: An improved method of concentrating milk and milk mixtures, and apparatus therefor
IPC: A23C1/12
Filed: 1935-02-19
Abstract: <PICT:0433678/III/1> In a continuous or intermittent process for the concentration of milk to obtain evaporated or condensed milk wherein the milk is passed through a number of heating units B, B<1>, B<2>, kept approximately at the same temperature, and intermediately through vapour separating chambers C, C<1>, C<2> communicating with each other, part of the milk foam produced in the heating unit B is carried, with the water vapour boiled off from the milk, from the separator C to the separator C<1> wherein the foam is dispersed by the more concentrated milk; the foam-free vapour proceeds to the separator C<2>, the total vapour from thence to a cooling condenser 1 and the concentrated milk to a container A<3>.  The complete plant is evacuated by connecting the condensate withdrawal pipe 2 of the condenser to an air pump, thus facilitating the removal of water vapour from the separators through the vapour pipe 4, and the circulation of the heating water around the tubes of the units B, B<1>, B<2> (which is introduced as steam from a nozzle 30 into a conical inlet pipe 13) through the connecting pipes 15, 17 and return pipes 18, 16, 14 to the condenser.  Part of the total vapour proceeding to the condenser is caught by the steam from the nozzle 30, the friction causing slight superheating of the steam. The vapour pipe 4 is made larger than the return pipes 18, 16, 14, so that the vacuum on the boiling side is higher than that on the heating side. Milk is fed to the plant from a supply tank 24 by opening the inflow valve 19, the milk being drawn by the vacuum through the headers 23, 22 of a preheater arranged within the condenser.  The milk foam produced during the first boiling is dissipated by the introduction of the fresh milk to the first separator.  The condensed milk collector A<3> is connected to a withdrawing pump 9 suitable for drawing from vacuum.  For the addition of sugar to the milk, the concentrated milk is drawn off from the container A<3> into one or other of vessels D, E, circulated through a pipe-system including a pump 69 and the sugar added from a hopper 71 during the circulation. In a modification of the process, for concentrating pre-sugared milk to which cocoa and vegetable fat may be added to produce milk chocolate, the milk supply tank is replaced by two hoppers, one containing the sugared milk to be treated and the other, which is hot water jacketted, cocoa and vegetable fat which are added after the milk has been partially concentrated.  In this modification the plant is operated on the batch system.  The process may be applied to the concentration of buttermilk, sour milk and whey.  Specification 395,957 is referred to.
