Title: Improvements in or relating to radio receivers
IPC: H03G3/26
Filed: 1946-10-05
Abstract: 624,522. Automatic noise suppression. HUGHES, D. H., CLARKE, D., and PYE, Ltd. Oct. 5, 1946, No. 29741. [Class 40 (v)] A radio receiver is muted by means of a rectifier which forms a low impedance shunt across the audio amplifier, but which is so biassed from a D.C. amplifier as to become non- conductive when the signal input exceeds a predetermined level. The audio amplifier (not shown) includes an attenuator comprising series resistance 8, Fig. 3, and shunt elements formed by diodes 4, 4a in series with audio byepass condensers 6, 6a. The diodes are connected in series between an adjustable source of positive potential 5 and the anode of a D.C. amplifier 2, resistances 11, 11a maintaining the correct distribution of D.C. potential. The amplifier 2 is connected to the signal detector, or in a frequency-modulation receiver to the limiter so that the anode potential rises as the signal input increases, causing the diodes to cut off and the muting to be removed when the predetermined level is reached. The arrangement may be simplified by omitting the diode 4, and further by using the valve 2 as the audio amplifier (Figs. 1, 2, not shown). In an arrangement in which the muting level depends upon the signal to noise ratio, the D.C. amplifier 2 as described above derives a first D.C. potential from the detector 12, Fig. 4, over a filter network 25, 26, 27. A noise amplifier 16 is coupled to the detector over a high-pass filter 14, 17 which attenuates audio signals but passes noise of higher frequencies, and is biassed over a network 18, 19, 20 so that the gain is reduced as the signal increases. The output of the valve 16 is rectified by a diode 21 and is applied to the valve 2 in opposition to the first bias.

Title: Vending apparatus

Abstract: 1,130,968. Article dispensing apparatus. TATEISI ELECTRONICS CO. 4 July, 1966 [10 July, 1965], No. 29951/66. Heading A4T. Vending apparatus is provided with a number of credit card actuated selling machines A, B, C, Fig. 1 (not shown), connected to a common unit R, for checking a card, recording a transaction and permitting vending from a machine, by circuits which lock out the other machines when one is connected to the unit. The transaction takes place in a first stage in which the correct positioning of a metal insert on the inserted card, via proximity switch 24, Fig. 2, illuminates at 25 a transparent card portion for a photoelectric reader 26, 28 and, via relay X1 and bistable circuit F1, allows a calling signal from continuous pulse generator PG to pass at 31A (or 31B, 31C), Figs. 2, 3, to unit R, R accepts the signal if it is not occupied with other calls, via a changed over bistable switch, e.g. F41, Fig. 3, and, via OR gates (O41-O43), blocks the bistable switches F42, F43 associated with the other machines and returns a "first arrival" signal to the machine via e.g. 32A which cancels the calling signal and prepares AND gates A1, A2 controlling card acceptance and reject circuits, and to AND gates A101-2, A201-2, A301-2 whereby a customer's number read from the card is checked against an "invalid number" store 7, Fig. 1, and proved to comprise four digits by a circuit, Fig. 4 (not shown). The card availability period is read and checked at 28, and if the card is acceptable in all respects, a relay X2 actuated via AND gates A4, A1 and receiving valid card signal at 61, energizes a price selection circuit in the machine and cancels the "first arrival" signal so that unit R is free to accept other calling signals. If the card is unacceptable, solenoid SO is energized via NOT circuit N2, or invalid card signal line 62, through OR circuit 03, AND circuit A2 and relay X3. A second stage of the transaction begins with the approved customer operating an article price selection switch S1-S3 which via a holding relay AX11 or 21 or 31 sends a calling signal to unit R which, as before, returns a "first arrival" signal enabling the customers' number via 30A and a digital price from diode matrix DM and lines 34 to reach a record device 8 via lines 43, 44, after which an "end of record" signal at 81 releases the card and energizes an article release circuit so that custom closing of a switch AS1-AS4 energizes an article release solenoid M1-M2. The relay AX4 then opens contact AX41 to release holding relay AX5 which returns the machine to initial condition and the "first arrival" signal is cancelled to again free unit R. If single price articles are sold from a machine, the second stage may follow immediately after the first.

Abstract: 511,732. Door fastenings. YOUNG, W. Oct. 24, 1938, No. 30667. [Class 44] [Also in Group XVIII] A fastening for doors, hatches and other closures comprises shafts 9 mounted in bearings 10 adjacent opposite edges of the door 1 on its inner face, the shafts carrying a number of spaced hook-like arms 14 adapted, when the shafts are rocked, to engage inclined faces on brackets 16 secured to the fixed frame. Additional similar hook-members 36 may be provided on short shafts 37 adjacent the adjoining edges of the door, shafts 37 receiving movement from shafts 9 through gear sectors 40. These shafts are rocked by means of a shaft 22 mounted in a bearing 21 passing through the door and carrying a plate 25 with eccentric slots 26 engaged by pins 27 on links 28. The inner overlapping ends of the links are slotted to embrace and be slidably guided by shaft 22, and the outer ends are pivotally 'connected to the ends of arms 29 fixed on shafts 9, so that sliding movement of the links consequent on rotation of plate 25 rotates shafts 9, 37 to swing the hooks 14, 36 into or out of engagement. Rotation of shaft 22 is effected by outside handle 31 or inside handle 32 which is preferably integral with plate 25. The links 28 and plate 25 have co-operating cam surfaces which give the inner ends of the links an arcuate movement similar to that of the ends of arms 29. To ensure closure of the door sufficient to allow engagement of the hooks, outside handle must be engaged behind an upstanding guide 33 on the fixed frame adjacent the door edge. To allow lateral adjustment of brackets 16 to compensate for wear &c. they are fixed by bolts 56, Fig. 5, passing through slots in the base plates 17 of the brackets, the inner face of the base plate housing serrations which engage serrations on a fixed plate 60.
