Title: Liquid cooling apparatus
Inventor: PRING EDWARD JOHN
IPC: F28F25/02
Filed: 1968-12-03
Abstract: 1278418 Direct-contact cooling of liquids SERCK INDUSTRIES Ltd 15 Oct 1969 [3 Dec 1968] 57388/68 Heading F4K Gas-liquid contact apparatus in which a downward flow of the liquid is cooled by an upward flow of air, consists of interengaged and similar cooler sections 23 stacked one upon the other, each section having transverse members (e.g. bars 46) therein to promote splashing of the liquid. The air stream may be either a forced or induced flow effected by a fan. Fig. 5 shows one arrangement in which a plurality of the cooling sections 23 are mounted on an air inlet section 24. Above the cooling sections is a liquid distribution section 30 and a suction fan section 31. The liquid distributing section 30 includes mist eliminators 39, Fig. 6, located above distribution gutters 34 having openings 36 at their upper edges to permit overflow of the liquid on to the splash bars 46 of the sections 23. Liquid is conveyed to the gutters 34 either through pipes 35 protruding from a trough 32 or alternatively through an arrangement of distributing pipes (42, 43, 45, Fig. 9). Each section 23 is square or rectangular in plan so that adjacent sections may be turned relative to one another. The interengagement means is such (see e.g. Figs. 3a-3e) that the sections may be stacked without bolting them together.

Title: Electric Resistance Welding Device
IPC: B23K11/36
Filed: 1978-07-24
Abstract: An electric resistance welding device such as a C-shaped spot welding gun has its movable electrode 3 extending from one arm 2 of the gun's C-yoke 1. An air cylinder 8 for moving the electrode is attached on the opposite side of the arm. A package 39 of parallel copper strips is bent to U-shape and surrounds the arm 2 below the air cylinder 8.

Patent GB-2006435-A (GB)
Title: Contact Sensing Probe
IPC: G01B7/012
Filed: 1978-10-20
Abstract: A contact-sensing probe has a contact element (11, 21) which includes a transducer (13, 17) which converts a varying electrical current into vibration of the contact element, or vice versa. A sensing circuit (25A) detects engagement of the contact element with an object by sensing the consequential change in electric current passing through the transducer. Preferably, a driving transducer (13) vibrates the contact element in response to an applied alternating current (29). The vibrations are damped when the element contacts an object, and this is detected by the sensing circuit either by a parameter change (29, 30) in the applied alternating current, or by a parameter change (27, 28) in a current generated by the vibrating contact element in a generating transducer (17). The probe can be used in a conventional length measuring machine (Fig. 14, not shown) such as is employed in engineering for measuring workpieces. It provides higher sensitivity to contact than most conventional probes.   <IMAGE>

Title: Apparatus for Use in the Simultaneous Testing of a Plurality of Storage Cells
IPC: G01R19/165
Filed: 1979-03-16
Abstract: Storage cells (12a, b... ) under test are connected in series to be discharged by a constant current supply (9) via relay contacts (RL1a1, RL1b1 ... ) which permit each cell to be bypassed as soon as its voltage has fallen to a predetermined level. A separate isolated power supply (14a, 15a, 16a, 17a) is provided for each cell and a thyristor (18a) is connected in series with the cell and the associated relay coil (RL1a) across this supply. A reference voltage is applied to the thyristor gate so that when the cell voltage falls below this reference voltage the thyristor turns on and energises the relay to bypass that cell. The discharge time is indicated by a timer connected to additional relay contacts RL1a2. <IMAGE>

Title: Paper feed mechanism for a printer
IPC: B41J11/38
Filed: 1979-06-04
Abstract: Paper is fed by a pair of sprocket wheels with teeth 17 mounted on a shaft 19 driven by a ratchet wheel 61 which is rotated by a pawl 62. The pawl 62 is pivotally mounted on the armature of an electromagnet 64 and is biassed by a spring 65 which holds the pawl against the ratchet wheel and also actuates the paw to advance the ratchet wheel after the pawl has been disengaged by the electromagnet. An arm 70 attached to the armature of the electromagnet allows manual advance of the paper by actuation of the ratchet wheel. <IMAGE>
Patent GB-2029867-A (GB)
Title: Single needle selection device for flat knitting machines
IPC: D04B15/70
Filed: 1979-07-02
Abstract: In a flat knitting machine, each needle 7 in needle bed 1 is selected to knit by being pushed leftwards as shown Fig. 3 by movement of push-rod 8 when its foot 9, in a raised working position engages a cam groove 14 on a carriage traversing the machine. Each push-rod 8 is engaged by auxiliary push-rod 10 provided with feet 11 and 12 in bed 2. As the carriage passes, firstly a cam 15 thereon acts on foot 12 to depress push-rod 10 which lowers push-rod 8 and foot 9 to a lower working position below cam groove 14. Depression of push-rod 10 causes foot 11 to displace a pawl 17 axially rightwards against a spring. This pawl movement pivots the lever near to an electromagnet which, if energised, holds the lever to lock the displaced pawl 17 so it cannot prevent push- rod 10 rising under action of spring 23 when cam 15 has passed. Foot 9 is thus lifted to the raised working position to be moved leftward by cam groove 14. If the electromagnet is not energised, pawl 17 is returned by its spring leftwards to engage above foot 11 and so hold down push-rod 10. Thus foot 9 remains in the lower working position and is not moved by the cam groove 14. <IMAGE>
