Title: Improvements in or relating to photographic camera shutters
IPC: G03B9/08
Filed: 1942-02-03
Abstract: 555,137. Photographic shutters. KODAK, Ltd. Feb. 3, 1942, No. 1442. Convention date, March 28, 1941. [Class 98 (i)] In a camera shutter requiring setting before an exposure, and having two control dials for adjusting separate mechanisms giving respectively a high and a low speed range of automatic exposures, the control dials are connected by interlocking mechanism so that only one may be adjusted at a time. As shown, the shafts 15 and 29 of the knobs controlling the high and low speed mechanisms carry respectively a disc 16 with a notch 17 and a disc 26 with a cut-away 27. A slidable interlocking member 19 pressed downwardly by a spring 22 carries plungers 18, 25 the latter of which, in the position shown, engages in the cut-away of the disc 26 and so prevents rotation of the low-speed adjusting dial. When the highspeed dial is adjusted to " neutral " the slot 17 is opposite the plunger 18. The low speed dial may now be turned, upon which the disc 26 forces the member 19 upwardly and the high-speed dial is locked by the plunger 18 entering the slot 17. The Specification as open to inspection under Sect. 91 also describes the shutter mechanism described in Specification 555,136. This subjectmatter does not appear in the Specification as accepted.

Title: Echo traps for telecommunications systems
IPC: H04B3/20
Filed: 1972-01-14
Abstract: 1358457 Echo traps SIEMENS AG 14 Jan 1972 [29 Jan 1971 3 Aug 1971 (3)] 1827/72 Heading H4R An echo trap in a four wire section of a transmission system includes means to block the transmit path when speech is detected on the receive path, a comparator which compares signals related to the speech levels on both paths and arranged to prevent said blocking when both paths are actively carrying speech and means to actively vary the relationship between at least one of said signals and its related speech level. The arrangements described allow a party to more easily break into the conversation while the other party is speaking. Various arrangements are described. All allow the comparator to be normally set to respond to a very low level of speech on the transmit path and have provision to either reduce this level throughout the conversation taking into account the echo attenuation of the level hybrid and/or to temporarily reduce this level for a short period, related to the actual or anticipated echo transit time delay through the hybrid, whenever the incoming speech level reduces. All embodiments reduce the chance that the comparator will respond falsely indicating that both subscribers are speaking when the echo of a received signal after delay and attenuation is comparable in magnitude to the level of a currently received low level signal. The embodiment shown adjusts either at the beginning of each call or periodically while the connection is being maintained to set the comparator input sensitivity in accordance with the measured echo attenuation of the hybrid 1. As shown speech on receive EL is detected by amplifier 7 and diode 9 and enables a blocking element 12 on the transmit path SL unless a comparator 10 which compares a fraction of the speech signal on SL with a fraction of the signal on EL that existed prior to a delay # (set in element 26) corresponding to the anticipated echo transit time of the hybrid 1 determines that conversation in both directions is taking place. A control unit 17 which may operate in analog or digital fashion adjusts the effective levels at which the comparator responds by controlling a variable attenuator 16 and a variable amplifier. The unit operates when blocking element 12 is active adjusting the attenuator 16 and the amplifier 18 until control inputs via a fixed attenuator 19 and diode 20 and via a diode 21 are equal. The fixed attenuator has a value 6dB the least anticipated attenuation of the hybrid.

Title: Improvements in or relating to scraper attachments for tractors
IPC: E02F3/64
Filed: 1948-01-26
Abstract: 650,618. Load-handling machines. FERGUSON, Inc., H. Jan. 26, 1948, No. 2248. Convention date, Jan. 4, 1947. [Class 78 (iii)] [Also in Group XXI] On the hydraulically adjusted draw-bars 21 of a tractor is pivotally mounted a U-shaped yoke 31, the lower and rearwardly inclined portions of the limbs of which are pivotally attached to a scoop 30 at a point 42 situated ahead of the centre of gravity of the scoop. The yoke is attached at its centre portion by a lost-motion connection 49 to a link 33a secured to a crank arm 15 mounted on the tractor so that, as the scoop is dragged through the ground the link 33a is kept in compression and, should this compression force on the link become excessive, a predetermined compression of the spring occurs causing operation of the hydraulic system so that the draft arms 21 are rotated about the pivots 22 and the scoop is lifted. When in normal use, the scoop is filled, the draft arms and scoop are raised and, owing to the C.G. of the scoop being to the rear of the point of suspension, it rotates until abutments 60 on the scoop engage lugs 61 of a locking device 32 pivotally mounted on the yoke so that the bucket is tilted slightly to the rear and thus spillage is prevented. The latch means is constrained to engage blocks 60 by a spring between the arms 63 and the side arms of the yoke. Associated with the top of the yoke are pivoted arms 70 the forward ends of which are slidably supported from the link 33a and which carry between them a pivoted hook 74. As the scoop is raised, the lost-motion connection rotates to stretch rearwardly so that the hook moves rearwardly of the member 33a to engage the cross bar of the latch. To trip the latch to allow the bucket to rotate and dump rearwardly, the draft arms are lowered sufficiently to allow some forward movement of the draft linkage which thus causes the hook to move forward and trip the latch. The scoop is reset by lowering the draft arms as the tractor moves forward so that the bucket which is in contact with the ground is rotated back into its original position. Pivoted member 85 on the yoke can be rotated from one side of a stop 87 to the other to permit engagement of the latch or not as desired. When it is desired to use the scoop for levelling purposes, the catch is released permitting it to swing backwards into the dump position and pivoted stop 82 mounted on the yoke is interposed between the yoke and the scoop to maintain it in position. The link 33a and the lostmotion connection may be released by a telescopic link. Specification 470,069, [Group XXXI], is referred to.
