Title: Improvements in or relating to feed-regulating mechanism for machines used in the preparation of flbrous materials for spinning
IPC: D01G23/06
Filed: 1929-05-23
Abstract: 333,939. Dobson, B. P., and Pickup, J. H. May 23, 1929. Openers etc.; feeding openers &c.-The rate of feed of cotton &c. through a hopper feeder 24, Fig. 1, is caused to control the feed through a hopper feeder 14 by means of a finger 30, Figs. 1 and 4, which when defected by accumulated cotton brings a stop 48 into the path of a pawl 40 reciprocated by a cam 36 so as to hold this pawl and a companion pawl 44 out of engagement with a ratchet wheel 41 which is then free to revolve under the influence of a weight 60, so that through the links 54, 56, 58, 59 it moves a flexible element 62 extending across an intermediate horizontal opener 16, to a hook on a bell-crank 75, Fig. 2, which operates the belt fork rod 72 of the speed gear 22 of the hopper feeder 14 and opener 16, so that the feed is reduced. The ratchet wheel 41 is normally rotated step by step by the pawl 40 so as gradually to speed up the feed to a maximum corresponding to a gap 42 in the teeth of the ratchet wheel 41. Pawl 44 serves to prevent reverse movement of the ratchet wheel 41 until both pawls are held out of engagement by the stop 48. The two pawls may be replaced by two friction blocks similarly actuated. The feed of the intermediate machine may be controlled directly by attaching a rod to the arm 58, Fig. 4, which operates the belt fork of the intermediate machine. Machines of different kinds may be thus combined, e.g., hopper bale breakers, the hopper feeds of openers, porcupine openers, openers which make laps, soft waste openers, or exhaust openers.

Abstract: 681,816. Tea infusers. TEEPACK SPEZIALMASCHINEN GES. June 22, 1949 [July 8, 1948], No. 16575/49. Class 129. [Also in Group XVII] A folded packet adapted for use as an infusing device in making tea &c. is formed by folding a sheet of waterpermeable paper or perforated transparent film longitudinally inward along two parallel lines to obtain a flattened tube with one edge overlapping the other, and then folding the tube transversely along two parallel lines f<SP>1</SP>, f<SP>2</SP>, thus providing two compartments g', g<SP>2</SP> with their longitudinal seamed portions d towards each other, the space between the compartments providing a partition h such that, when the compartments are filled with tea &c. and secured together at their upper ends, the swelling of the contents due to immersion in an infusion liquid causes the seamed inner walls of the compartments to press one against the other, at least over a short extent. The position of the transverse folds f', f<SP>2</SP> is also such that the compartment g' is of greater depth than g<SP>2</SP>, thereby providing a closing flap i the corners of which may be folded inwardly upon the open end of compartment g<SP>2</SP> before the central portion. The closing flap may be secured by a clip k which extends over and around the seam d. The clip may also serve for the attachment of a holding- string or the like e. As shown in Fig. 2 the overlapping longitudinal edges which comprise the seam d are folded inwardly, together in successive folds; a reinforcing wire, or a holding string, or a narrow metal band may be located within the fold. A third transverse fold may be formed between the folds f<SP>1</SP>, f<SP>2</SP> so that the partition h has the form of an inverted V. More than two compartments may be obtained by repeated transverse folding of a long tube. The Specification as open to inspection under Sect. 91 states that the tube may be seamless. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in or relating to continuous cycle absorption machines for producing cold or heat
IPC: F25B15/10
Filed: 1938-06-03
Abstract: 515,543. Refrigerating. POEL, W. F. June 3, 1938, No. 16700. [Class 29] Absorption systems.-In a continuous-cycle inert gas system the refrigerant vapour formed in the evaporator 9 passes by diffusion into the weak inert gas flowing from the absorber 15, while the gases are in contact in a plane parallel with a horizontal direction of flow. The liquefied refrigerant from the condenser 8 is cascaded over flanged plates 10, 11 in the evaporator, and where a light inert gas such as hydrogen is used the gas vapour mixture descends to the bottom of the evaporator. The absorber is formed as a sinuous coil and a circulation of inert gas may be assisted by an ejector nozzle 22 supplied with pressure vapour from the rectifier 6. The weak inert gas flows through a pipe 20 and gas heat exchanger 30 to an inverted trough shaped member 24 located around the wall of the evaporator. The refrigerant vapour passes by diffusion into the gas in the trough and the mixture is led through pipe 26 to the absorber. The trough member may as shown be entirely open at its lower face, or be covered by gas-permeable fabric sheets or perforated metal plates. Where a heavy inert gas such as nitrogen is used the trough may be located with its open side uppermost at the top of the evaporator. In a modification, shown in Fig. 3, a. diffusion chamber 35 is arranged below the evaporator. The invention may be employed with the usual water and ammonia systems and with water and sulphurous acid systems.
