Abstract: <PICT:0960709/C1/1> In apparatus for drawing sheet glass from a molten glass meniscus, the drawing zone is closely surrounded by a drawing chamber partly defined by cooled walls closely adjacent the glass at the terminus of said zone, to define a constricted channel and extending outwardly and downwardly to a horizontal plane passing through the meniscus, access of air to the drawing chamber being substantially solely by way of the constricted channel.  In the form shown, the sheet 10 is drawn upwardly from the bath 12 through a chamber 37 defined by coolers 34 hinged to the L blocks 24 and providing a channel 35.  The hinged joints are either substantially airtight or the entry of cold air is prevented by flames above them. The ends of the coolers are sealed to the side walls.  In another form the lower end of the chamber 37 is completed by inclined inner faces of the L blocks into which coolers are recessed. From the channel 35 the sheet 10 passes through a chamber 22, to which air may flow through coolers 26, between V-shaped catch pans 30, formed as coolers, to the drawing rolls 18. Specifications 884,330 and 908,149 are referred to.

Abstract: 926,655. Moulding uppers. SOUNDWELL INVESTMENTS Ltd. Nov. 28, 1961 [Dec. 1, 1960; June 22, 1961], Nos. 41369/60 and 22712/61. Class 87(2). A method of making an upper comprises vacuum forming a sheet of thermoplastic material 22 over a last 10 and a last carrier 17 and cutting away portions along edges 14 and 16. The last has a top edge 14 which defines the eventual top edge of the upper and a bottom edge 11 corresponding to the periphery of the insole which will be used, while the last carrier has a top edge 19 closely conforming with the bottom of the last but bounded by an edge 16 inwardly spaced from the edge 11 of the last by an amount corresponding to the eventual turn in-i.e. lasting allowance-of the upper. The last-carrier may have a passage 17a connected at 17b to a pump to assist in the formation of a vacuum. An insole may be placed, between the last and last carrier, with adhesive around its margin so that during the vacuum forming of the upper the insole is stuck to it. Support components, such as a toe puff or a counter stiffener, may be placed on the last, preferably in a recess so that there is a smooth surface for the upper, with adhesive on their outer surface so that they are stuck to the upper. The upper material may be polyvinyl chloride with preferably the outer surface grained to simulate the grain side of leather-or any desired finish-and the inner surface flock coated to simulate the flesh side of leather. The first Provisional Specification includes the step of pulling a lining over the last before the addition of the outer.

Patent GB-1020217-A (GB)
Title: Improvements in or relating to safety devices for filters
IPC: B01D35/143
Filed: 1963-01-15
Abstract: When a filter functions normally, the mechanical resistance of a diaphragm 37g, Fig. 1, (not shown), opposes its deformation, but when the pressure difference between duct 5g (joining the filter inlet to the region below the diaphragm) and duct 6g (joining the filter outlet to the region above the diaphragm) exceeds a given value the diaphragm deforms until it touches a terminal 58 above it.  Such touching closes a warning circuit through diaphragm and terminal.  In Fig. 2 (not shown) the terminal is replaced by a bimetallic strip so that excess pressure difference due only to high viscosity caused by low temperature of the liquid, e.g. oil, being filtered will not operate the device.

Title: Foaming apparatus
IPC: E04B1/76
Filed: 1967-09-20
Abstract: 1,201,775. Mixing apparatus. CRANE FRUEHAUF TRAILERS Ltd. 20 Sept., 1967 [24 Oct., 1966], No. 42748/67. Heading B1C. [Also in Divisions F1, F4 and H2] Apparatus for mixing two constituents from tanks 20, 22 for making plastic foam has controls for maintaining a constant flow rate of each constituent from a pump, in spite of variations in line pressure. As described, the mixture is supplied to insulate a cavity 14 in a vehicle body through a pipe 64 which is withdrawn gradually by rollers 66, the mixture entering the pipe within a housing 70. The pipe is slit within the housing and therefore reduces in effective length as it is withdrawn, causing a reduction in pressure loss through the pipe. The pressures in the lines 38, 40 from the tanks are maintained constant by controls 46, 52 for electric motors 44, 50 driving separate pumps 34, 36 for the constituents. The control (Fig. 5, not shown) senses the armature current and varies the armature voltage to give a voltage which increases with increasing load, to compensate for pump slip, and therefore provides a constant flow rate. The flow rates may alternatively be controlled by modifying the characteristics of the pumps or of the lines from them, and the line pressure may be sensed instead of the motor current.
Patent GB-1021633-A (GB)
Title: Fluid pressure relay or valve
IPC: G05D16/16
Filed: 1962-11-13
Abstract: 1,021,633. Fluid pressure servomotor system. POWERS REGULATOR CO. Nov. 13, 1962 [June 11, 1962], No. 42844/62. Heading G3P. A fluid relay comprises a fluid balanced first valve member 66 controlling the flow from a supply chamber 72, connected to a supply passage 62, to an outlet chamber 70 and a second valve member 90 controlling the flow from the outlet chamber 70 to exhaust or atmosphere. The first valve member 66 is a ball fixed to the end of a two part spindle 76, 112, the two parts being fixed together to clamp a diaphragm 106. The diaphragm 106 is fixed between two housing parts 52, 104 so that the effect area of the diaphragm subjected to inlet pressure is equal to the area of the valve member 66 subjected to this pressure. The spindle 76, 112 has an axial bore and steps 122a, 122b on the spindle are equal to the area of the valve seat whereby the outlet pressure existing in chamber 70 has no effect on the valve member 66. Springs 112, 118 act on the valve spindle in opposite directions, the forces due to these springs being equal when the valve 66 is closed. As described, the relay is responsive to a temperature signal provided by a bimetallic element 30 and the outlet signal controls a valve in a heating or cooling system. The element acts on the ball valve 90 against the output pressure and when the element moves downwards, the valve 66 opens to increase the output pressure which pressure then increases the force acting on the element through the ball 90. Movement of the valve 66 also provides a force, due to the expansion and contraction of springs 118,112, to reclose the valve. When the element 30 rises, the valve 90 opens to release output pressure until the reduced force acting on the valve allows the element 30 to reclose the valve 90. In a modification, the bore in the spindle is replaced by an exterior connection to a diaphragm chamber formed in the valve housing to provide the output pressure balancing force.

Title: Improvements in and relating to hypodermic syringes
Inventor: SLOME DAVID
IPC: A61M5/00
Filed: 1968-04-08
Abstract: 1,241,571. Hypodermic syringes. D. SLOME. 2 April, 1969 [8 April, 1968; 11 Sept., 1968], Nos. 16774/68 and 43115/68. Heading A5R. A hypodermic syringe comprises a barrel 3, a needle 8, a protective cover 2 engageable over the barrel 3 and first and second puncturable containers 21 and 11 housed in the cover 2. The containers 21 and 11 contain fluidizing medium and a fluidizable medicament or drug respectively. The position of the barrel 3 within the cover is limited by a detachable split collar 19 and a spring clip 20 engageable in a circumferential groove formed in the surface of the barrel 3. With such an arrangement the barrel 3 is locatable in three different positions within the cover 2; the needle 8 may lie adjacent the first container 21 or may have punctured the first container 21 or may have punctured the second container 11. In an alternative arrangement for limiting the position of the barrel 3 in the cover 2, the barrel is formed with two diametrically opposed lateral shoulders and the cover is formed with two diametrically opposed longitudinal extensions which in one relative rotary positions of the barrel and cover are engaged by the shoulders to retain the needle adjacent the first container and in another relative rotary position the lateral shoulders pass between the aforesaid extensions to allow needle to puncture the first container. Further means are provided to prevent the needle prematurely puncturing the second container. The syringe needle 8 has an outer tubular needlelike covering member (22, Figure 2) freely surrounding the needle and shorter in length than the needle. Such an arrangement allows the passage of sterile air, contained in the cover 2, to be drawn up past the needle 8 and into the containers 21 or 11 during the withdrawal of their contents into the barrel 3.

Abstract: 937,249. Machine tool details. IAN NICKOLS Ltd. March 19, 1962 [Dec. 19, 1960; May 31, 1961], Nos. 43559/60 and 19633/61. Class 83 (3). A method of monitoring a stepping switch sequence control system for an automatic machine comprises a timing device which is set to zero at the completion of a cycle of operations, and energizes the emergency circuit of a warning system, if the cycle is interrupted. The timing device may be a timing switch, a rotary switch, a magnetic tape or punched paper. When a magnetic tape is used, the recorder, driven by a synchronous motor, starts to operate when the machine start button is pressed, thus actuating a stepping switch. The subsequent steps of the switch are recorded and when the machine cycle is completed, the recorder is switched to rewind, a photo-cell being used to indicate the starting point of the record. The tape is played back, and the timer stepping switch is actuated by the recorded impulses. The steps may be recorded by punched holes in cards or tape, inked marks picked up by a light cell, or pins pushed into a drum or belt.

Filed: 1967-09-25
Abstract: 1,167,556. Machine tool for machining die cavities and punches; polishing. MARKGR€FLICH BADISCHE INDUSTRIEVERWALTUNG G.m.b.H. 25 Sept., 1967, No. 43590/67. Headings B3B, B3D, B3K, B3L and B3T. A machine particularly intended for planing and polishing the internal faces of a polygonal cavity of a die to be used for cold forming nuts, or the faces of a matching punch, comprises a chuck 6 which is rotatable about the longitudinal axis of the workpiece 7 and which is indexible into angular positions corresponding to the faces to be machined, and a tool holder 4 including a tool 9 with cutters mounted to oscillate about an axis 10 normal to the machined flat surface within a preadjustable lateral amplitude and associated with means for feeding the tool in the axial direction of said cavity. The oscillatory motion of the tool holder is preferably generated by means of an adjustably eccentric disc 19 carried by a rotary disc 20 driven by motor 46 through flexible drive means 45. The tool holder and the eccentric drive discs are mounted on a longitudinal slide 15 mounted on a cross slide 23 supported by a member 25 which is tiltable about a pivot 26, the whole being vertically adjustable on columns 29. Feed motion of the slide is derived from a motor 49 through worm gearing 52 which is disengageable to allow the slide to return under the action of a spring 54 and under dashpot control (Figs. 8, 9, not shown). An adjustable stop 63 engageable with a stop switch 65 can be used for predetermining the extent of infeed of the tool. The chuck 6 is carried in a spindle head 70 by a spindle 68 which carries also a notched index plate 69; a manually engageable and disengageable sliding detent 90 co-operates with the plate 69 to arrest the chuck and workpiece in the desired angular position. The detent 90 is mounted on the spindle head 70 for slight pivotal adjustment so as to allow for slight angular adjustment of the index positions in which the chuck 6 and workpiece are located. The entire spindle head is pivotable about a pivot 72 and also about a vertical axis on the spigot 73. Provision is also made for longitudinal adjustment of the frame member 5 on which the spindle head is mounted, by means of a manually operated rack and pinion 79, 80. With the detent 90 withdrawn the spindle 68 and chuck 6 may be rotated by belt drive 99 from a motor 98 so that the machine may be used for turning or polishing, e.g. an end face of the workpiece. The tool 101, Fig. 10, may be shaped to provide two cutting edges 105 and particularly two forward cutting points 109. Alternatively a diamond pointed tool (Fig. 15, not shown) may be used or a polishing or grinding tool 9b having grooves 113 extending transversely of the direction of oscillation and adapted to receive a grinding or polishing paste. It is stated that a conventional grinding or milling attachment can be mounted on the toolholder, e.g. for machining a bevel edge on the end surface of a workpiece.
