Title: Coating hot glass with metals or metal compounds, especially oxides
IPC: C03C17/00
Filed: 1981-01-26
Abstract: In the formation of a metal or metal compound coating on a face of a heated glass substrate during its forward displacement by contacting such face at a coating station with at least one stream of droplets comprising one or more substance from which the coating is formed, problems are encountered in controlling the thickness of the coating.   To facilitate such control, the or each droplet stream (21) is downwardly inclined towards the substrate (4) in the forward (6) direction or in a rearward direction, and at least one current (25) of preheated gas is discharged into the environment above the substrate (4) to flow in the same forward or rearward direction as the droplet stream(s) (21) and into contact therewith, the preheated gas current temperature being such as to influence the temperature of the droplets on their way to the substrate. The preheating of the gas may be automatically controlled in dependence on signals from a device (not shown) for measuring the coating thickness. Coatings of uniform or varying thickness and comprising the oxides of Sn (optionally doped with Sb, As or F) Cd, Mg, W, Fe, In, Ti or Co may be produced. <IMAGE>

Patent GB-2075843-A (GB)
Title: Heart stimulator for controlling tachycardia
IPC: A61N1/372
Filed: 1981-03-25
Abstract: In a heat stimulator for controlling tachycardia, following tachycardia confirmation, a burst of at least three stimulating pulses is generated. The time intervals between successive pulses decrease by a fixed decrement; thus the rate of the pulses increases during each cycle of operation, the burst being more accurately characterized as a "chirp". The time delay between the last heartbeat which is used to confirm tachycardia and the first stimulating pulse in the chirp is equal to the time interval between the last two heartbeats, less said fixed decrement. Because successive pulses are generated at an increasing rate, and because the first pulse is generated at a time which is actually dependent upon the tachycardia rate, there is a greater likelihood that tachycardia termination will be achieved. Each burst of stimulation may be terminated after a predetermined length of time or when a predetermined number, e.g. in the range of 10 to 20, of pulses has been supplied. When, towards the end of a burst, reduction of the interpulse interval by the fixed decrement would result in an interval below a minimum "safe" value, the intervals for the succeeding pulses in the burst are maintained at equal values above this minimum. If tachycardia is not terminated, different values of the decrement may be selected by the apparatus for successive bursts. The stimulator may be externally programmable to change a stored value corresponding to said minimum value and to change the decrement value and the number of pulses per burst as well as other parameters relating to tachycardia detection.

Title: Forming joints
Inventor: BROOKS DOUGLAS HARRY MERIDEW
IPC: B29C65/42
Filed: 1981-08-03
Abstract: Two elongate wooden members 2 each have a mitred end face 4, and are each clad with a plastics cover sleeve 6 which extends beyond the end face 4. The wooden members 2 are positioned at 90 DEG  to each other so that the end faces 4 are parallel to but spaced from one another by a gap 8. To cement together the two end faces 4 and the internal surfaces 10 of the plastics sleeves 6 a thermoplastic resin is introduced into the gap 8. To retain the unset resin in the gap 8, a suitably shaped restraining frame 12 is located around the gap 8 and the projecting portions of the sleeves 6. In another joint of the invention a hollow restraining frame is located in the gap between the wooden members to support the projecting portions of the cover sleeves. <IMAGE>
Patent GB-2082024-A (GB)
Title: Television ghost detector system
IPC: H04N5/21
Filed: 1981-08-06
Abstract: A television ghost detector system is provided which receives a training signal component of the video signal (e.g., the sync signal in line ten) followed by a signal interval which may contain a ghost of the training signal. The training signal activates a reference signal circuit (8,76) for producing a varying search signal. A signal generator (78,80) is responsive to said search signal and produces a sequence of identification pulses. The identification pulses are compared in a coincidence circuit (74) with the video signal interval following the training signal, and a coincidence signal is produced when a ghost appears in time coincidence with an identification pulse. The coincidence signal causes the value of the varying search signal to be stored as an indication of the delay of the ghost with respect to the training signal. During subsequent training signal intervals, an identification pulse is produced only when the search signal attains the previously stored value, and the identification pulse is phase compared (84, 86) with the ghost to update the stored value to a more precise value. If the ghost is lost or disappears, the system verts to its initial mode of operation. <IMAGE>

Title: Mould cooling means
Inventor: FRANKLIN GARY WALTER
IPC: B29C35/00
Filed: 1982-07-14
Abstract: A cooling circuit of equipment, such as an injection moulding machine (not shown), has cooling passageways to an input end of which one end (4) of a duct (2) is connected and to the output end of which one end (10) of a second duct (9) is connected. Cooling liquid is supplied to the duct (2) at an end (3) thereof, passes through a solenoid shut-off valve (5) and through a manual (6) or automatic (6a) pressure reducing valve, a pressure sensor (7) indicating the pressure. Liquid entering the duct (9) at (10) has its pressure sensed by a pressure sensor and indicator (12) and is drawn in by an electrically driven self-priming liquid ring pump (13). Downstream of the pump are a pressure switch (14), an air/water separator (15) and an automatic air eliminator (16). The pump (13) creates a suction in the duct (9) and in the cooling passageways of the equipment, and the valve (6 or 6a) is adjusted until the sensor (7) shows zero gauge pressure. The passageways thus operate at negative pressure so that air or gas drawn into the passageways can be pumped by the pump (13) with the liquid and be separated out in the separator (15). In the application of use with an injection moulding machine, by using a porous core in a wall of the mould cavity, the negative pressure in the cooling passageways can be used to extract air and other gases from the mould cavity. <IMAGE>

The shells may have extensions which meet over the joint, or there may be an intermediate split tubular sleeve (10) spanning them. A heat shrinkable wrapping (11) is applied over the adjacent ends of the shells and any intermediate sleeve to close off the air space in which the joint lies. <IMAGE>
