Title: Dehydrating apparatus
IPC: C04B11/028
Filed: 1958-07-16
Abstract: <PICT:0897926/III/1> <PICT:0897926/III/2> Dehydrating apparatus for gypsum comprises a drum rotatable about its major axis having an accordian-like structure extending lengthwise through said drum, the drum having a first opening for receiving a solid, a closure means for the first opening, an opening into the interior of the accordion-like structure through which heating medium is introduced and a second opening for exhausting the heating medium on to the exterior of the drum.  As shown in Figs. 1 and 2 a drum 6 is supported by, and rotates about, an axial pipe 21 which rests on rollers 5.  Inside the drum the tube 21 carries an accordion-like arrangement of annular dished members 26 peripherally joined at 28 to form a series of chambers communicating with the interior of pipe 21 through perforations 25.  A gas burner 22 delivers a blast of hot combustion products into pipe 21 from the left-hand side and these gases pass through perforations 25 into the chambers 33 formed by the annular dished members 26.  The chambers 33 communicate with tubes 8 (Fig. 2) formed in the walls 7 of the drum by means of pipes 30. Tubes 8 are provided with exhaust passages 31 having terminal elbows 32, whereby the hot combustion gases from chamber 33 pass through connections 30 into tube 8 and out through exhausts 31 in contact with the exterior of drum 6.  Gypsum is fed to the drum through removable closures such as 11 and the steam formed by dehydration is vented through valves 13.  As shown in Fig. 2 the valve 13 is operated by a lever 16 carrying a roller 18.  The latter abuts a valve operating cam 19 which is manually adjustable so as to release steam pressure as desired when the drum rotates.  In operation for the dehydration of gypsum, gypsum pieces having a maximum dimension of one inch are fed to the drum in an amount sufficient to permit relative movement between the pieces of gypsum on rotation.  The steam tight closures 11 are sealed and the drum rotated.  The pressure rises to about 35 p.s.i.g. as the gypsum becomes heated and thereafter rises to about 40 p.s.i.g. as dehydration commences.  The cam 19 is thereupon adjusted to release the steam pressure, and as dehydration proceeds the valve 13 is opened progressively wider until at the end the pressure has dropped to atmospheric.  The drum may be preheated before introducing gypsum to a temperature of about 300 DEG F.  During dehydration the temperature remain at about 250 DEG  F. and may be raised to about 270 DEG  F. at the end of the operation. Specifications 866,126, 897,924, 897,925 and 897,927 also are referred to.

IPC: H04L27/14
Filed: 1970-07-28
Abstract: 1305789 Digital transmission system SIEMENS AG 28 July 1970 [29 July 1969] 36456/70 Heading H4P A threshold detector circuit on a frequency or phase modulated system for distinguishing between data signals and parasitic voltages has a first response circuit enabling, above the threshold level, a first timing element which establishes whether the level has been undershot during a given first interval and if so produces an output the same as that which was present prior to the commencement of the overshooting, and any undershooting switching a second timing element which establishes whether the threshold is exceeded during a second interval producing an output which was present prior to the commencement of the undershooting, any changes in level beyond the threshold causing enablement of the other timing element each of which gives a different output signal at the expiry of its period.  Amplified input signal E is applied to a threshold detector SW driving a trigger circuit TR producing above the threshold level reset pulses (2) from the carrier frequency each of a half period duration. Each pulse (2) is fed to a circuit which discharges a capacitor operating in a fixed time constant circuit and charged from a supply.  Beyond threshold level the capacitor charges and at a determined level produces a negative pulse controlling a timer Z2. Above the threshold positive pulses are produced controlling a timer Z1 which at a first interval produces an ON condition signal at terminal A. If during the first interval a negative pulse appears, timer Z1 is stopped and Z2 is started, which if no positive pulse appears during a second interval maintains circuit AS in the off condition. A circuit having two threshold levels established by Zener diodes with a "deadband" between is described in detail in connection with Fig. 2 (not shown).

Title: Multi-dose needle-less hypodermic jet injection device
IPC: A61M5/30
Filed: 1960-10-26
Abstract: 959,397. Hypodermic syringes. A. ISMACH. Oct. 26, 1960 [Dec. 14, 1959], No. 36830/60. Heading A5R. A needleless hypodermic syringe has a rear chamber 10 and a forward medicament chamber 39, a piston 12 movable rearwardly in the rear chamber against a bias by hydraulic fluid directed into the rear chamber, a plunger 36 reciprocable in the forward chamber and responsive to movement of the piston and means for releasing hydraulic fluid from the rear chamber. Hydraulic fluid normally circulates continuously from a pump (not shown) through a normally open loading valve 78. On depressing a cocking trigger 74 mounted on a handle-grip 21, the valve 78 is closed so that hydraulic fluid flows through a conduit 87 to open a check valve 82 and thence into the rear chamber 10. The fluid moves the piston to compress a spring 16. The plunger 36 which is detachably secured to the piston is moved rearwardly so that medicament is drawn from a bottle 58 into the forward chamber 39. On releasing the cooking trigger, hydraulic fluid again circulates through the loading valve 78. On depressing a firing trigger 76, a release valve 86 opens and fluid flows from the rear chamber to the pump thus releasing the spring 16 so that the piston and plunger are projected to eject medicament through an outlet valve 44 and an orifice in a sapphire insert 46 in the syringe nozzle. The stroke of the piston and plunger, and thus the volume of medicament drawn into and ejected from the medicament chamber, may be adjusted by a screw 24 which adjusts the position of a thrust ballbearing 26 against which the spring abuts. The bottle 58 is supported on the body of the syringe. Medicament passes from the bottle to the medicament chamber by way of an extraction pipe 54, a check valve 48 and an inlet tube 52. Medicament in the bottle is replaced by air passing through a filter 60 and a tube 55 part of which is concentrically arranged inside the extraction pipe 54. Specifications 798,826 and 798,827 are referred to. Reference has been directed by the Comptroller to Specifications 798,826 and 798,827.
