Title: Improvements in and relating to feed mechanism for punching machines
IPC: B21D43/06
Filed: 1939-03-03
Abstract: 525,923. Metal-strip feeds. STOREK, E., STOREK, G., STOREK, H., and STOREK, H. (trading as Storek 1., [Firm of]. March 3, 1939, No. 6977. Convention date, March 3, 1938. [Class 83 (iv)] In a feed mechanism for a punching-machine wherein the feed of a strip 1 under a punch 3 is produced by a feed member engaging in the punched holes, the feed member 4, Fig. 2, has at least two feed claws 5, 6 engaging in successive holes I, II or groups of holes and spaced at the required pitch t of the holes or group of holes. When a new strip is started in the machine, holes I, 11 for engagement by the feed member are first provided in the end of the strips. If a single feed claw 2 is employed, Fig. 1, and the spacing of these holes differs by an amount e from the correct spacing t, then the first feed step l<SP>1</SP> produced by the claw 2 will be equal to t - e and the second feed step l<SP>2</SP>, equal to t + e. Thus feed steps alternately smaller and larger than the correct pitch t will occur. Owing to the deformation of the material the large gap b between the holes tends to become greater and the small gaps c to become less until overlap of the holes may occur. When, according to the invention, a two-claw feed member is used then with the work set to engage the claw 6, the claw 5 will be out of contact on account of the incorrect pitch of the holes. When the feed member is advanced to the punched hole III only the claw 5 will be in contact so that the next hole IV will be at the true pitch t from the hole III. The claws 5, 6 may be on separate levers and if the holes are punched in two or more rows the claws may engage in holes of different rows. For staggered holes, Fig. 3, pairs of claws 7, 8 and 9, 10 may be arranged on a common carrier 11 and located on opposite sides of the strip to prevent lateral movement thereof. In another modification two claws may be carried on a common lever, one of the claws being adjustable by a screw or other means.

Title: Improvements in or relating to process of and apparatus for treating sewage and other waste liquors
IPC: C02F3/12
Filed: 1944-04-17
Abstract: 587,400. Treating sewage &c. INFILCO, Inc. April 17, 1944, No. 7054. Convention date, April 21, 1943. [Class 111] An activated sludge process of treating sewage and other waste liquors includes the steps of passing the sewage through an aeration zone, clarifying aerated sewage, discharging the clarified sewage to waste, returning bacterial solids separated from the clarified sewage to the aeration zone, and continuously mixing with the sewage entering the aeration zone unclarified aerated sewage taken from the outlet of the aeration zone in an amount controlled to produce a calculated time period for normal flow through the aeration zone. The amount of aerated sewage returned is preferably such that the time of flow of mixed liquor once through the aerator approximates to the time taken for the bacterial activity to reach its maximum. In the arrangement shown in Fig. 1, sewage after being partly purified in a primary clarifier 11, passes through conduit 15 to an aerator 16 containing air-diffusers 19. Baffles 21, 22 are provided to distribute the flow of sewage. The outlet pipe 23 is connected to a conduit 24 through which aerated sewage is recycled by a pump 25 back to the inlet 15 of the aerator. The pipe 23 also leads to a sedimentation chamber 28 from which clarified liquid is discharged through an outlet'35. Sludge is moved by raking mechanism 29 to an outlet 30, part of the sludge being discharged through a conduit 31 and part being returned by conduit 33 to the inlet end of the aerator. In a modification the aerator is divided by partitions into basins, each with a mechanical aerator. Fig. 5 shows respiration curves in which are compared the oxygen utilization of a conventional activated sludge plant (A) and a plant (D) in accordance with the invention, in the latter case sewage passing through the aerator in one hour, while due to recycling its total time in the aerator is three hours.

Title: Improvements in or relating to wireless receiving systems
IPC: H04N5/60
Filed: 1935-03-07
Abstract: 453,484. Multiple wireless signalling. COSSOR, Ltd., A. C., BEDFORD, L. H., and PUCKLE, O. S., Highbury Grove, London. March 7, 1935, No. 7174. [Class 40 (v)] An intermediate-frequency amplifier V3 in an ultrashort wave superheterodyne receiver handles both television and accompanying sound on separate carriers, and the sound is separated by a circuit SF and applied to a detector V8 and soundreproducing system V9, LS in a broadcast receiver for longer waves. It may also be amplified in an intermediate-frequency amplifier V7 in the superheterodyne broadcast receiver. Automatic gain-control voltages produced in the broadcast receiver are used to control the intermediate - frequency amplifier of the television receiver. The condensers for tuning the television receiver are mechanically coupled to the condenser for tuning the broadcast receiver and may be uncoupled to tune the broadcast receiver without disturbing the television receiver. Separate oscillators V0, V10 generate the local oscillations for combination with the ultra-short and longer waves respectively, and a switch S2 causes either to function according to the desired signal. A dipole aerial D for receiving the ultra-short waves can be used as an ordinary aerial for receiving the longer-wave broadcast signals when required. A switch L enables the broadcast signals to be received on either a separate aerial A or the dipole aerial system D, T1. The dipole aerial is connected by a feeder to an ultra-short wave transformer US coupled to the short-wave receiver V1 . . V5, and a shield SH round the feeder is connected at one end to the centre of the dipole and at the other to the centre of the primary winding of the transformer US. A connection T1 between the centre of the primary winding and an input terminal T3 of the broadcast receiver enables the aerial to be used for the longer waves. Switches S2, L, S1 may suppress both oscillators and connect the aerials to earth, when it is desired to reproduce local signals from, e.g. a pick-up.
