Patent GB-236588-A (GB)
Abstract: 236,588. Lumpp, C. July 4, 1924, [Convention date]. Driving-mechanism.-The cam carriage 6 is reciprocated by means of an endless belt or rope 4 to the upper and lower runs of which an arm 7 is alternately clutched. A clamp 9 is movable vertically on guides 10 to clamp the belt against either an upper or a lower rib 8 of the arm 7 by means of a sliding bar 11 connected to the guides 10 by pins and horizontal slots 12 and to the clamp 9 by an inclined slot 14 and a pin 13. The bar 11 is operated at the end of the traverse by impact with spring abutments 16, which can be adjusted to suit the width of fabric to be produced. The apparatus is driven by frictional engagement of the pulley 2 with the face of a motor-driven disc, from which it can be disengaged by a hand-lever. Modifications are described in which the bar 11 is replaced by tappets, toggles or inclined grooves and springs. In a further modification the bar 11 is retained, but the guides 10 are mounted on a slide and can move relatively to the arm 7 to provide for secure clamping when the belt thickness is irregular.

Title: A signalling mechanism for use in dictating machines
IPC: G11B5/004
Filed: 1958-07-23
Abstract: 848,648. Centralized dictation systems. COMPTOMETER CORPORATION. July 23, 1958 [Aug. 23, 1957], No. 23660/58. Class 40 (4). [Also in Group XXXVIII] A belt-record magnetic dictating machine, which may have one or more remote dictation points, has a warning buzzer, duplicated in each of the remote handsets, to indicate firstly if the machine is in an operable state for dictation and secondly, during dictation, to give a preliminary and then an urgent warning of the impending end of available recording time. The machine functions are controlled, proximally or remotely, by a selective push-button 184 on any handset, as described in Specification 838,401. The mechanism, generally described in Specification 764,352, includes a carriage 24, more particularly described in Specification 791,785, guided on a rail B, driven by a leadscrew F and carrying a head 22 movable in and out of engagement with a perforated belt record D driven by the roller C. Indexing arrangements are described in Specification 819,772. A switch 80 takes up alternative positions a, b according to the position of the head 22 and its contacts 88 are made in the " a " position. A circuit (Fig. 8, not shown) associates these contacts with the " record " position of the button 184 to sound the buzzer when the button is pressed. The switch 80 travels with the carriage 24 and an actuator 90 engages a nut-like member 74, mounted on the leadscrew F to give an intermittent warning when the end of the record is approaching. Further movement of the carriage to the right engages the ramp 114 against a member 116, to move the switch 80 to a third position to give a continuous, urgent warning of the imminent end of the record.

Abstract: 915,168. Strap fastenings. HARLEY PATENTS (INTERNATIONAL) Ltd., and HARLEY, F. B. July 3, 1961 [July 8, 1960], No. 23993/60. Class 44. A releasable connector comprises a cup 20 having apertures 50 to receive plates attached to the shoulder and lap straps of a safety harness, the plates being formed with holes 16 engageable with spring-urged bolts 52 which project through apertures in a disc 25 slidably mounted in the cup. The disc carries a post 29 formed with cam surfaces 30 and coaxial with a tube 35 provided with a transverse pin 39, the projecting ends of which act as camfollowers. An actuating knob 40 is secured to the tube 35 and has a central boss 45 having a cut 47 to receive the ends of the pin 39 so that rotation of the knob turns the pin and tube, the pin riding over the surfaces 30 to lower the post 29 and hence the disc 25. The bolts 52 are thus forced downwardly clear of the holes 16 so that the plates may be withdrawn from the connector, the bolt 60 still engaging the plate 11 so that the connector is permanently secured to a lap strap. A release member 70 is pivoted in an aperture in the actuating knob and has two projections 74 extending through a slot 75 and overlying the bolts 52 corresponding to the shoulder straps so that when the member 70 is depressed the projections force down these bolts so that the shoulder straps may be released from the connector.

Vaporizable organic compounds which have melting points above normal atmospheric temperatures, such as phthalic anhydride, are separated from non-volatile impurities, by melting the mixture and distributing the melt in the form of droplets in an evaporator 2 wherein the droplets are contacted with a hot gas (substantially free from molecular oxygen) whereby the organic compound is vaporized ; the mixture of vapour and gas is passed to a condenser/ cooler system 4 in order to separate the organic compound in liquid and/or solid form, and the gas is then reheated and recycled to the evaporator, from the base of which the non-volatile constituent of the starting-material is discharged. The molten material is conveyed to the evaporator from a heated reservoir 1 by pump 20 via a heatable tube 12. Inside the evaporator, the molten material is sprayed into droplets by a shallow bowl 11, preferably 16 to 24 cm/s. in diameter, which is rotated at a peripheral speed of 20-60 metres per second. The angle of pitch of the inner surface at the upper edge of the bowl is less than 60 degrees to the horizontal. Droplets having a size approximately 20-100 microns are obtained. The hot carrier gas may be carbon dioxide, or nitrogen obtained from coke oven gas, water gas or blast-furnace gas. Specification 937,904 is referred to.

The valve may be an electromagnetic valve controlled by an electronic timer through variable resistors 12, 10 which determine the inhalation period and respiratory cycle. In a modification the valve is opened via a plunger which is engaged by a roller having cam surfaces whose width tapers axially of the roller, the inhalation time being adjustable by axial displacement of the roller relative to the plunger. The respiratory cycle is varied by adjusting the speed of a motor driving the roller. The roller may operate a plurality of valves at rates suitable for several patients. In a further modification the valve is controlled by a pneumatic retropressure device which cooperates with a motordriven disc and has a nozzle fed with compressed gas located at right angles to the disc. At different radial distances the disc has at least one elongated concentric slot, the lengths of the slots varying and the inhalation period being determined by the length of the slot. In another modification the valve is operated by a piston and cylinder under the control of an air-pulse valve which is actuated via two air-pressure delay circuits each having an adjustable constrictor valve and a valve controlling the piston.
