As disclosed, the articles are bottles in a refrigerator 400 (Fig. 14) in a hotel room. Figure 16 shows the arrangements for an inclined bottle (at 414 in Fig. 14) and Fig. 21 for an upright bottle (at 416 in Fig. 14). In Fig. 16, when the bottle (not shown) is manually removed, spring 428 rotates cam 422 clockwise (as shown) since flap 420 on the cam is no longer held down by the bottle. A bent portion 430c of one end of a pivoted catch 430 (weighted at the other end 430a) engages a recess 422a in cam 422 to lcck it in position. A magnet 446 on cam 422 closes a reed contact-pair 148, so that a central computer in the hotel can detect the removal of the bottle and bill the guest accordingly. Use of a staff key (see below) energizes a solenoid to raise a bar 436 to disengage the catches 430, permitting replenishment of the bottles. In Fig. 21, when the bottle is manually removed, a platform 454 on which it stood is pulled up by a spring 462, the end 468a of a catch 468 is pulled into a recess 456a by a spring 468b to lock the platform in the raised position, and a magnet 474 closes a reed contactpair (not shown in Fig. 21) so that the computer can detect removal of the bottle as above. Use of the staff key (see below) energizes a solenoid 408 to disengage the catch 468. The refrigerator (Fig. 14) can be opened by a guest key (at 134) or the staff key (at 130). Use of the keys and whether the door is open can be detected by the computer. Opening using the guest key may be inhibited by the computer. The computer can also order the refrigerator to de-frost.

Abstract: 983,510. Viewing gems. D. A. ROBINSON, L.M. ROBINSON, and J.DODS. Dec. 28, 1961 [Dec. 29, 1980], No. 46425/61. Heading G2J. Apparatus for viewing an image of a gem includes a holder to support the gem, a light source to illuminate said gem and projecting means comprising a lens passing light from said gem to a concave mirror and thence directly to an observers viewing position substantially at the focus of said mirror. As shown (Fig. 1), an image of a gem 69 in a ring 68 supported releasably on a holder 65 is produced for observation or photographing through a window 18 by means of light emanating from a source within the holder 65 (an aperture 67 Fig. 4, is provided behind the gem) and passing to the window 18 by way of a lens 47 and a concave mirror 37. The lens 47 is interchangeable with a further lens 46 (Fig. 3, not shown) both lenses being supported on a laterally slidable holder 45. The mirror 37 is slidably supported on a mount 22 and is axially adjustable by a knob 27 coupled thereto through a threaded spindle 25 and a tapped lug 23. The mirror is pivotally mounted at 40, its angular position being adjustable by a knob 28 coupled thereto through means including a partly threaded spindle 31 which is telescopically coupled to a hollow shaft 29 for rotation therewith and a pivoted lever 34 which engages the rear of the mirror with its upper end 41, against loading of a spring 42. The apparatus is fitted with an adjustable forehead support 72. The holder 65 is adjustable as follows. Rotation of a knob 54 moves a first carriage 50 towards and away from the lens 47 (or 46) through a pinion and toothing 51. A second carriage 55 is similarly movable by means of a micrometer arrangement 59, 60. Rotation of a knob 63 causes vertical movement of the holder through a threaded shaft 64 which is keyed against rotation in support column 61. The holder may be rotated by means of a handle 66. Two shutter plates 79 (Fig. 4) adjustable towards and away from each other by a knob 81 and mounted in a frame 74 are adjustable towards and away from the lens 47 (or 46) by rotation of a knob 77. The knob 81 is calibrated and co-operates with a fixed index pointer 83 so that for example diameters of gems may be measured. A camera may be hingedly connected to the housing 11 in the region of the window 18.

Abstract: 1285736 Automatic proportioning control VYZKUMNY USTAV STAVEBNICH HMOT V BRNE 1 Oct 1969 [24 Oct 1968] 48340/68 Heading G3R The output of a grinding mill is supplied to a classifier and the ratio of the coarse to fine output or the ratio of the coarse or fine output to input of the classifer is used to control the rate of feed of raw material to the mill. In Fig.2, a device 12 controls the rate of feed of fresh material, e.g. cement, to a grinding mill 14 which includes a classifier (not shown) to produce an output of fine material J and return coarse material H to the mill input. The ratio of the rates of flow of coarse and fine material is measured at 17 and compared with a desired rate of flow, set at 20, so that any difference is effective through a proportional and integral regulator 10 and a proportional regulator 11 to eliminate error by automatically controlling at 12 the rate of feed of fresh material to the mill. A control term dependent on the difference between the rate of feed of fresh material and the rate of flow of fine material is produced at 18 and applied to the input of PI regulator 10. A further term, dependent on the sum of the rate of feed of fresh material and the rate of flow of coarse material is produced at 19 and applied to the input of P regulator 11. The ratio of the rate of feed to the classifier to the rate of flow of coarse or fine material may be substituted for the primary control in dependence on the ratio of the rates of flow of coarse and fine material.
