During the rotation of the block 12 about the shaft 11 and particularly at low travelling speeds of the holder 4 the guide roll 13 contacts the vertical surface 40 of a delay member 39 which causes the delay of the movement of the finger 30 to its open position, the delay member 39 being mounted in the path of the guide roll 13 and being freely swingable about an axis 37.  The holder 4 is connected to the support 1 by means of a balance arm 3 forming part of a balance, the rest of which is not shown, and a link 9 pivotally connected to both the support 1 and holder 4. As soon as an object is discharged from the fingers 30-32 the holder 4 is swung upwardly relative to the support 1 by means of the arm 3 and link 9 so that the said fingers do not contact the discharged object.

Abstract: 626,682. Reciprocating pumps. ROTHERHAM & SONS, Ltd., and BOLTON, W. C. E. Dec. 23, 1946, No. 37651. [Class 102(i)] In a pump having a cylinder 16, Fig. 1, with intake and discharge ends 17, 18 and a piston 11 forming a partition between the cylinder ends and being reciprocated from end to end of the cylinder by a block 13 slidably guided in a chord-wise slot 12 of the piston and engaged by a driving crankpin 14, the block 13 coacts with the ends of two passages 22, 23, Fig. 3, in the piston 11 to afford communication between the slot 12 and the cylinder ends 17, 18 to provide a transfer valve means between the cylinder ends. The passages 22, 23 are unevenly disposed on the same side of the transverse centre line of the slot and passage 22 is fully closed by the block 13 during the major portion of the discharge stroke. In order that on the return stroke liquid may pass from the cylinder space on the inlet to that on the delivery side of the piston through the open passages 22, 23, the inlet bore 17a is of less diameter than the passages 22, 23 or of the discharge bore 18a.

Title: Improvements in or relating to the heating or cooling of enclosures
Inventor: PAYNE NORMAN HORACE
IPC: F24F1/01
Filed: 1954-12-31
Abstract: 786,894. Ventilating, demisting vehicle windows of aircraft. NORMALAIR, Ltd.. Dec. 9, 1955 [Dec. 31, 1954], No. 37832/54. Classes 20(3) and 137 [Also in Group XXIX] In an arrangement for heating, or cooling enclosures such as aircraft cabins, a pipe 4, connected to a supply of compressed hot air, has an outlet nozzle b situated adjacent the entrance to the throat of a venturi c in a duct 2 to supply hot air thereto and for mixing, in the desired proportion, with cold air supplied, from a duct 6 to the upstream end of the duct 2. A valve, d controlling the outlet of hot air from the nozzle b, is connected by a reversing linkage f, g, h, i to a diaphragm valve 3 which controls the amount of cold air flowing from the duct 6 into the duct 2. The diaphragm e of the valve 3 is enclosed by a cap k forming an enclosure 5 which communicates, by means of a branch pipe f, with a source of compressed air x, e.g., from the cabin hood sealing tube, the valve 3, in this manner, being urged closed on to a seating a at the upstream end of the duct 2. A counterbalance spring j, constrained between the valve 3 and an abutment within the duct 2, tends to open the valve 3 and thus shut the valve d. The setting of the valves 3 and d, and thus the ratio of hot to cold air delivered by the duct 2, is controlled by the bi-metal strip 7 of a thermostat which operates a spring loaded valve m connected to the high-pressure pipe x a restricted passage o being incorporated in the pipe x on the upstream side of the branch pipe p. In operation should the air passing through the duct 2 become too hot the thermostat element 7 opens the. valve m which, due to the restriction o, reduces the pressure within the enclosure 5 and allows the spring j to urge the valve 3 further off its seat a allowing more cold air from the duct 6 to enter the duct 2, the valve d at the same time being pressed further towards its seating in the nozzle b to restrict the flow of hot air therethough. In a modification, Fig. 2, the shut off valve d and its operating rod f are of tubular form, the counterbalance spring being retained at one end on three projections. 10 carried by the valve 3 and abutting with its other end against a fixed bracket 8. Levers 9, pivoted to the bracket 8, support at their outer ends a washer 11 which bears against the ends of the projections 10, their inner ends co-acting with a washer 12 on the outer end of a rod 13 screwed into the rod f. A spring 14 constrained between, the bracket 8 and the inner end of a cylindrical bore around the unthreaded portion of the rod 13, constantly urges the valve d towards its seat in nozzle b. The invention is particularly adaptable for supplying hot air between the layers of an aircraft windscreen.

Abstract: 1,64,754. Automatic control of aircraft. HONEYWELL Inc. Sept.27, 1963 [Sept. 27, 1962], No.38223/63. Heading G3R. An aircraft is automatically guided by signals dependent on roll attitude, lateral displacement from a radio beam, and heading of the aircraft relative to the beam, low frequency components of the latter signal only being introduced when that signal exceeds a predetermined magnitude. In Fig. 1, D.C. signals representative, in magnitude and polarity, of deviations in the heading of an aircraft from the heading of a radio beam, are applied from a directional gyro (not shown) to the input 26 of an amplifier 24 the output of which is applied, together with signals from the roll pick-off 78 of a gyro vertical (not shown), to an amplifier 18 associated with the roll channel of an automatic pilot (not shown), so that the aircraft ailerons are controlled to maintain the aircraft parallel with the beam. When it is desired to approach the beam a switch 32 is closed manually to energize a relay 30, contacts 36 of which then couple radio-derived signals representative of displacement and rate of change of displacement from the beam from an amplifier 12 to amplifier 20. At the same time contacts 44 are opened and contacts 40 are closed so that only high frequency components of the heading error signals are effective through network 56, 58. This results in an increasing angle of approach until the heading error signals are large enough to cause one or other of Zener diodes 72, 74 to conduct and introduce the low frequency components of the heading error signals. Finally when, due to reduction in displacement from the beam, the heading error reduces sufficiently, the Zener diodes again remove the low frequency components of the heading error signals for the final approach to the beam. Proper crab angle in a cross wind is obtained. Use of A. C. signals is referred to.
